Thanks for this info. I think I got one of these, but do you have to remove the case to reprogram it, and if so, how do you remove the case?
Thanks!
you put it with the USB-connector down vertically on the table and push the outer shell down towards the table.
Hello,
I have an USBISP too. It’s a MX-USBISP-V3.02 board (2014-10-08) with mega8 on it.
I have read a lot, but now I’m totally confused what to do.
When I’m trying to reprogram it with the firmware above, I get a first verify error on Adr. 0x0000.
(Cable-jumper between “UP”-pads is set)
Reading the fuses give: Low 0xFF, High 0xDF and Lockbits 0x3F (AVRDudess with USBasp programmer). I guess the Lockbits are the problem, but how to solve it? Changing the Fuses in AVRDudess didn’t work.
Can you help me to make the *isp to an *asp?
Gruesse
Werner
What programmer and program do you use to program the programmer?
Have you tried setting the transfer speed to a lower value (-B parameter in avrdude)?
I have used an usbasp-stick (fischl-clone) to program the cn-stick. BitClock was set to 8k and 1kHz – no change.
Hello,
thank you Fernando Sakugava!

Modified for use in the V3.02, which uses a Atmega88:
https://www.dropbox.com/s/88zve7kq2mc0h38/ATmega88.hex?dl=0
I bought an programmer with circuit description MX-USBISP-V3.02 201-10-08 with an atmega88.
It uses PID c8b4 and VID 03eb (c8b4:03eb) but i cant get it working.
With your HEX i got it, many thanks, now its a USBasp!
hi vendor, i also have problem with my USBasp v3.02…
could you please show me how to modify the source code and how to compile that?
maybe tutorial video or else..
thanks
Hi, could you show me the video tutorial to compile the main.c ?
i confuse with how to compile it
Hi Andi,
with the .hex file available you do not need to compile anything.
Otherwise: if you are using AVR-Studio you could create a new project with AVR-Studio, copy all necessary files (.c, .h, .asm, .inc, .S and the usbdrv directory) from my zip-archive into that project folder, add the files to the project and “build” it.
Please Read.
I have the exactly same problem for 2 days, and after reading this post relaxes me. Please help me how can i program my programmer using another programmer??
Hi there,
how can I help you – the procedure is described above: you need a working, other programmer and then you connect this one to MOSI, MISO, SCK, RESET, GND and VTG of the programmer you want to program. Additionally you have to set the jumper wire to connect the RESET signal to the AVR chip on the programmer.
OK i got it. I need a USBasp to convert it into USBasp?
I am a beginner, so one silly question.
Should i connect the MOSI pin of programmer to the MOSI pin of AVR or MISO pin of AVR?
and very thanks for the reply.
Thank you very much! I flashed a MX-USBISP-v3.02 into a normal usbasp.
I tought I wasted $3 on a broken programmer, but I flashed it using your instructions, and now it works flawlessly.
hi ,
first of all thanks for your effort but i have this problem ,
i bought several chinese version with ATMEL USB ISP version 2.0 written on the case ,i flashed your code it was seen as usbasp and the blue led worked , i changed the fuses once and anothe flashed it without fuses change , i program AVR using Khazama software
http://khazama.com/project/programmer/
i always get this error

I have never been using the Khazama software – the error message appears to point to a problem with the Windows driver libusb0-dll for the USB device. Please at least try to use avrdude from the command line to perhaps get a more detailed error message.
If you like a graphical user interface instead of a command line, consider AVRdudess.
Khazama’s current version is from 2011
AVRdudess is from 2013
it worked ,,, thhhhhhaaaaaannnnnnnkkkkksssss

You need to use the -B setting which you don’t know!
It determines the clock rate at which the bits are sent from the programmer to the AVR you want to program.
From your screen-shots you can see that it tries to burn the AVR at an SCK clock rate of 1500000 Hz or 1.5 MHz. According to the datasheet of an AVR, the SCK clock rate has to be less than 1/4 of the AVR’s own clock speed. If you have a brand new AVR than the clock speed is 1 MHz from the internal oscillator and this limits the useable SCK clock rate to 250 kHz.
See the documentation of avrdude and use the option -B 5 as a starting point.
In avrdudess which I recommended above you can select a suitable SCK clock rate from a pull-down menu.
The -b option is not relevant here, since we are not using a serial port to talk to the programmer itself.
Modified for use in the V3.02, which uses a Atmega88:
https://www.dropbox.com/s/88zve7kq2mc0h38/ATmega88.hex?dl=0
I tried that firmware and it works, I can use it with avrdude but LED is off, it is always off. This is the last part that should be addressed.
LEDs work. I found that one LED was demaged, I replaced it and it works ok (it is not easy task to replace SMD LED, I destroyed 5 before I did it correctly…)
BLUE LED is connected to PC0; well I am not sure if it was BLUE, it was defective
RED LED is connected to PC1
PD6 is conected to PC0
PD5 is not connected to PC1 (jumper is missing)
It is possible that PD5/PD6 are used as a key to code PCB version or something like that.
My PCB is MX-USBISP-V3.02, 2014-10-08, MCU is ATmega88.
I bought new version, which uses ATmega88. How can I compile the firmware for this processor?
the simple answer: it might just run as it is…
the complicated answer: how do you compile your AVR code normally? If you use AVR Studio then you create a new project, select the ATmega88, copy the complete source code into this project and compile. If you compile using a MAKE file then you create a MAKE file where you set the correct controller.
All the internals of the source code should be compatible between the ATmega8 and ATmega88…
Dear uwezi: Thanks for the great instructions. I uploaded your firmware to a programmer that I got from DealExtreme (DealExtreme part number 151604), and the device now works perfectly as a usbasp. My device is almost identical to the one pictured above. The only difference that I can find is that the date silkscreened on my device is “2013-03-05”, and the silkscreened text is in a different place on the board.
Hi.
I have 5pcs V3.02 and check again. I put new Atmega8 from shop and now I can read signature and program uC. In new version V3.02 pin reset is disabled. This is problem because I don’t have HV programmer.
are you sure that it was the “reset disable” which was the problem and not a “lock fuse” which can be reset using a complete chip erase cycle?
I was able to re-program v3.02 boards without needing to get out the chip and use high-voltage programming.
Great work!
Now the nice programmer works like a charm!
Thank you
Man,
you saved my day, thank you very much, I had this piece of device for some time and today took the time to hack it as you suggested.
Now works like a charm, for information I did not changed the Fuse, Just erased the chip, then flash the hex file and setback lock bits to original PROG_VER, LPM and SPM ALL disabled
For information my original Fuse were set to :
High=0xCF, Low=0xFF
Changing according what you wrote just change
High => bootsz 128W_0F80 to 1024W_0C00
Low => CKSEL from 64ms to 4ms
I think you can let them as original, and avoid the tricky touch fuse part than can sometime brick the device (in case of problem) so my 2cent advice is not touching the fuses, they worked before they should work after, it’s the same device.
May be we could do some tricky old red LED blinking when programming 😉
I also have buy one o this USBISP, mainly for the nice aluminium case.
After a couple of tryes to make’it work like a USBASP whithout hardware modification I have concluded that best wai is to make’it USBASP hardware compliant.
Mine was having botd PD3 and PD2 directply connected to USB port D- and D+ and the LED’s were in antiparalel between PD5 and PD6.
So I cut the trace on PD32, PD3, PD5, PD6 and between LED’s at one end.
After that I put 2 68ohm resistor on the zenner diodes and rewire from them to PB0 for D- and PD2 & PB1 for D+.
The common of the LED’s I connected to +5V thru a 1K resistor, I desolder one led and put’it same as the other one (anode to common +5V) and the cathodes I connected to PC0 and PC1. You can also put different collors. To program I use Another USBASP and a wire jumper for Reset.
Result: one nice piece of fully compatible USBASP.
HTH.
Paul
These sound like much more modifications than should be necessary…
…but if it works for you – the better.
I’m using an arduino uno as isp (the -c arduino is for programming the arduino itself).
I already double checked the connections and tested the arduino with another chip (and it works), however i keep getting that error about the device signature.
When i try it with the “-F” option:
avrdude -c avrisp -P/dev/ttyACM0 -b19200 -p m8 -v -e -B 5 -F
I get:

i also tried to connect to the device to check its signature with:

but, without the “-F” option, all i get is the error i mentioned before, and with the Force option i get:

1) are you sure that you are using the correct “-c” setting in avrdude? As I wrote earlier, I am not sure since I have never ever used a programmed arduino as a programmer…
2) all you seem to be getting back on the MISO-line between the arduino and the chip to be programmed appears to be 0s – in the signature, in the verification step,… to me it appears that this is where you have to start looking: loose wire, disconnected solder bridge,…
when i try to fully erase the atmega8 with:
avrdude -c avrisp -P/dev/ttyACM0 -b19200 -p m8 -v -e -B 5
(or try to set the fuses, or to flash it, or simply connect with it)
all i get is:

Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
i’ve been googling about it, but i can’t really figure it out.
is the chip locked?
I’m just a bit confused about your settings
What programmer are you using now?
What happens if you try using the
setting to override all warnings?
According to the messagens from avrdude from when i try to erase the chip, the task was completed.
But when i try to set the fuses
avrdude -c avrisp -P /dev/ttyACM0 -b 19200 -p m8 -v -U lfuse:w:0xef:m -U hfuse:w:0xc9:m -F

Wich took some time.
I have the hw v3.02 and I cannot update the firmware.
I’m using an original AVR ISP mkII with AVR Studio.
I connected everything, even tried to switch MISO with MOSI, but there is no reply from the chinese microcontroller.
The reset signal is correct and the jumper is inserted.
Same problem here. MX USBISP v3.02 (bought mid december), unable to program or erase with avrdude. While attempting to program, there’s no response on MOSI whatsoever, even though all other signals look just fine.
I guess it’s time to make a follow-up on this one – I now have 3.00, 3.01 and 3.02 boards and I succeeded to reprogram all of these in the same way – but some of the boards were more problematic than others. Apart from the obvious – like a too fast speed from the programmer (some ATmega8’s seem to be slower on the ISP than specified) or lock-fuses (which can be reset by a complete chip-erase cycle) – I have the strong feeling that I lately only succeeded with one particular board, [b]because I held it in my hand during programming…[/b] (could it be a floating pin?)
You should definitely not need to switch MOSI and MISO! I have one v3.02 which I was not able to reprogram and 2 where I had absolutely no problems. The difference between the versions seems to be only that the solder-pad jumpers on the back side are not closed on the newer boards, but I am not sure…
A new update on the matter!
Recently quite a few eBay-stores have started selling a new version of the programmer in the same aluminum case. These programmers have the printing “Atmel” on the front together with a printing of the connections on the 10-pin programming header.
These programmers do not need to be reprogrammed, but already contain the correct Fischl-compatible firmware and not the weird and crappy Chinese software.
This is the new type:
eBay 281353519099
This appears to be the new type:
eBay 301128314029
Appendix 2014-11-07
I just noticed that the firmware in these new-type USB programmers is not the latest version of the Fischl-firmware. It does not allow avrdude to set the clock speed on the programming port. However, the circuit board inside the new-type programmer is exactly the same as shown above and readily accepts the firmware version which you can download from the link above. In order to program the programmer you will again need another programmer and additionally you bridge the two pads marked “–>UP<--".
Hi. I have this avr programer with new PCB ver. MX USB V3.02 and one old AVR with V3.00 PCB. When I connect old vesion to other programer I have connection and can read signature and write new firmware. With new PCB 3.02 I can’t connect with atmega. Only RC-1. PIN reset on old pcb have about 0V when I connect -UP-. On new PCB V3.02 olways have 3,6V on PIN RESET. On new PCB atmega8 is closed for LOCK FUSE or have change RST PIN for other function? Any idea ?
Hello Paul,
I have the same problem. The Version is V3.02 Date 2014-10-08. You can`t change the firmeware. I use PROGISP 1.72 from http://www.zhifengsoft.com. I Think, the RESET-Pin is disabled.
I tested Version V3.00 2013-03-15. Here you can change the firmeware without any problems. The pcb-layout is nearly the same, only two brighes are different. The atmega8 are the same. I killed the brighes – no effect. This is made in china-rubbish!
Hi Paul, what error message do you get, when you connect the new programmer?
a) “Target doesn’t answer”
b) “Cannot find device with VID… PID….”
In case (a) the problem is that your programmer is trying to talk too fast to the target AVR chip. This can because the firmware in the programmer either is not able to set a different speed, or because you did not choose a slower speed from the avrdude options.
In case (b) you don’t have an avrdude-compatible firmware in the programmer.
What do you mean with “RC-1”???
The reset-pin should only have 0V when it is connected through the -UP- bridge AND you are trying to program it from another programmer AND only during the short programming attempt – I would not expect you to see this with a regular multimeter.
If the LOCK FUSE is set on the Atmega you can still erase the complete chip including the LOCK FUSE and then re-program it with a new firmware. Only if the manufacturer has disabled the reset pin with the corresponding fuse you would not be able to reprogram the chip using the ISP-interface at all. But I have not seen this yet – neither on 3.00 or 3.02 programmers – both of which I have by now bought from different European and Asian sources. (I have some throughput here, because I needed to get more programmers for my students nd by now I also had to replace 2 broken programmers).
Hi,
I feel I should warn you: my programmer came with the “Atmel” logo and pinout printed on the case, and it still had the Chinese USBISP firmware. So I fear that this case isn’t a guarantee that you will receive it with USBasp.
I have to admit, though, I never tested mine (v3.01 board) with the unmodified USBasp firmware. I went straight to using yours.
Has anyone got this full c file converted to Bascom so i can port it another chip type? The chip on board i have got is an ATMEGE48p
Thanks Snow
The problem would not be to translate it to Bascom, but that the code size exceeds the flash memory size of your ATmega48!
You can (and in my opinion should) program the ATmega48 in C the same way you can program any other ATmega or ATtiny in C. Trying to do the same in Bascom will most certainly not make the code smaller.
The older – but still fully compatible – 2009-version of the Fischl AVRUSB firmaware still fits in a ATmega48. You can find it here: http://www.fischl.de/usbasp/ and the zip-file even contains a pre-compiled .hex-file for the ATmega48.
Hello, I have MX-USBISP-V3.01 and It works well by using your firmware.
However I get an error when I tried to write hex file to Attiny10 by TPI.
When I watched at Thomas Fischl ‘s web site, and found that usbasp.2011-05-28.tar.gz supports TPI.
I think that the failure due to the version of the firmware.
So, I tried to make hex file using AVRstudio6.2, but I have failed because I do not know the way.
Please tell me the way of making firmware, or make a firmware using the latest source files?
Moments ago , I tried WINAVR.
As a result , I was able to create the latest firmware that corresponds to the MK-USBISP.
Thank you.

You can find the documentation for avrdude here.
To make a long story short, the syntax for the U-option is:
-U memtype:op:filename[:format]
In order to give a value for a fuse on the command line you need to terminate the -U with :m, otherwise avrdude is looking for an external file – this is what avrdude tries to tell you with avrdude: reading input file “0xc9″.
Once avrdude discovers a problem in the command line it will never do anything, but completely abort the operation before any harm could have been done!
The correct command for you would (probably) be:
avrdude -c arduino -PCOM4 -b19200 -p m8 -v -U flash:w:”C:\Users\Owner\Desktop\20130212_mega8_usbisp.hex”:a -U lfuse:w:0xef:m -U hfuse:w:0xc9:m
…but I never change fuses and burn the flash in a single run – I always do this in separate steps…
So, to do it in separate steps with an arduino, i should first use the command:
avrdude -c arduino -Pmyport -b19200 -p m8 -v -U lfuse:w:0xef:m -U hfuse:w:0xc9:m
To fully erase the chip, then:
avrdude -c arduino -PCOM4 -b19200 -p m8 -v -U flash:w:”C:\Users\Owner\Desktop\20130212_mega8_usbisp.hex”:a
To flash new firmware.
Is that correct?
Your first line only sets the fuses, but does not erase the chip. To fully erase the chip you need to send
Also, I have never used an Arduino as a programmer and I cannot find whether the Arduino supports the -B option. But if you want to program an ATmega8 using a USB-programmer then you also need to give a -B 5 to slow down the bitrate between programmer and target chip…
The line:
“avrdude -c arduino -Pmyport -b19200 -B 5 -p m8 -v -e”
Gets me this error:

Sorry for the long reply. Also, sorry if I’m not making much sense. Microcontrollers are quite new to me.
in the line
you of course need to replace “myport” with the actual portdescription on your system. Also if you are using the Arduino as a programmer you first need to load a corresponding sketch into the Arduino.
What disturbs me a bit is that you get messages about the STK500-programmer back… even if I have nothing connected to my computer, I get a more helpful feedback from avrdude using the exact same command.
If you are new to avrdude I would recommend you to get a graphical user interface to this tool – I use it all the time! E.g. avrdudess or AVR burn-o-mat
That worked like a charm. I successfully uploaded a test sketch using the programmer.
Thanks a lot for your help and for the beautifully detailed article.
I have the same kind of programmer and I have followed your instructions, using an Arduino ISP to program it with the .hex file from the ZIP archive: 20130212_mega8_usbisp
Seemed to work fine. I’ve got the blue light.
BUT the hardware information panel of my Mac says that the device is not configured, even though it is recognized by my Mac as a USBasp.
Now I don’t know how to access it with avrdude (there is no device corresponding to it in /dev !)
Could somebody help me?
Thanks!!
Got my answer somewhere else: the device to use with avrdude is simply “usb”. So the command line is for example :
avrdude -C./avrdude.conf -vvv -e -patmega2560 -cusbasp -Pusb -b19200 -t
Great !! Thanks to all!
Thank you so much for this article. My board is marked v3.01, dated 2013-11-07. I have reprogrammed it with your modified firmware, and it seems to be working fine.
Hello, I got one exactly like yours,i am no newbie to computers but can I reprogram this unit on it’s own? or I need another one, thanks
Paul
You cannot program a programmer on it’s own. You will need another programmer: borrowed from a friend, an Arduino, or a very simple programmer…
I do not know if it’s just me or if perhaps everyone else
experiencing issues with your site. It appears like some of the text in your content are
running off the screen. Can someone else please comment and let me know if this is happening to them as well?
This may be a problem with my browser because I’ve had this happen before.
Thank you
I usually check my pages with Firefox, Opera and in very rare cases Internet Explorer and I cannot reproduce any strange behavior…
Which browser are you using?
I also have this useless programmer and I’d like to reflash it using the modified software. But could you please provide me with any way of how I’m suppose to connect my external usbasp programmer to program atmega8 on this usbisp programmer board. Should I connect directly to the pins on smd chip or some other way?
Please. This is urgent.
I really wouldn’t call these programmers useless. They have a comparatively high quality.
You program the programmer by connecting another programmer 1:1. MISO-MISO, MOSI-MOSI, SCK-SCK, RESET-RESET, GND-GND and VTG-VTG. Additionally you need to short the on-board jumper as described above.
So I should connect my external programmer to ISP socket of the programmer I’m programming and short circuit rst pin on the board?
Yes, you connect the two programmers with a standard 10-pin cable and set the jumper on the programmer which needs to be programmed.
Only the programming programmer should be attached to the USB port of zour computer at that time.
Just see the programmer as an AVR target system, which you want to program.
Oh I see. I just thought that MISO,MOSI,VCC,SCK,RST in ISP socket of the programmer which I/We want get reprogrammed are not connected with pinouts marked on the above pictures. So what I did was interface with those tiny holes but it worked. Anyway. As you said it. I could connect the two programmers with standard 10 pin ISP interface without the need of trying to put wires through those small holes.
Thanks. I think that there are others who also didn’t know that.
So to sum up:
USB-10pinISP ==10pinISPcable== 10piISPsocket + short circuit RST on the board.
You can find the schematics of the USBasp programmer on Thomas Fischl’s homepage. There you can see the connections in detail.
When programming an AVR chip with the programmer, the programmer takes the role of Master and the target becomes the Slave, thus MOSI goes from the programmer to the external AVR chip.
When programming the programmer, the other programmer becomes the Master, and thus MOSI goes from the other programmer to the one you want to program.
This way you can understand that the wires can be connected 1:1 with the exception of the Reset-line. The latter is because the programming (Master) AVR chip cannot control its own Reset pin and at the same time remain ISP-programmable.
Hello everyone!!!
I am trying to implement the USBasp Programmer by fischl on hardware. So far, I have had no success in making this. I wanted to try it on Breadboard first. I used universal programmer from my university lab to burn the firmware. I burned the hex file in “bin” folder for atmega 8. I set the fuse bits to HFUSE=0xc9 LFUSE=0xef , as told in the readme file. When i connect it to computer, it is not recognized as USBasp, instead a notification pop ups, saying “USB Device not Recognized”. And i also tried to install drivers given in thr RAR file downloaded from fischl. I have checked the circuit many times and its fine by me. I can’t understand how to install drivers (nothing installs from that rar file – i copied libusb files to System32 and drivers folder). And is there any specific way to burn the firmware. I am stuck here…. and i really really need help…
Anyone here to guide me about what i am doing wrong, or atlest put me on the right path….
“you have tried to install the drivers” – well that is not enough, you will have to successfully install the drivers before Windows (I assume you use Windows..) will recognize the USBasp!
You write about drivers in a RAR file – well the original drivers come in a ZIP file from the address http://www.fischl.de/usbasp/. In this you will find Windows executable installers for both 32- and 64-bit versions of Windows which you will have to run with administrative rights.
comparing two schema show that the blob of solder onto ‘B’ should be removed and PD2 should be connected to PB1.
what is your idea mr.menzer?
best regards
mehdi
Gawsh dern it….I wish I knew WTH you all are saying.
I’ve just jumped into the MC thing and have a programmer on the way but, looks like I still wont be able to begin any fun because the programmer may not work with my diyduino according to what I’m reading here…but I dont know what- I dont know yet and the language used for these fixes is beyond me. anyone speak layman want to toss a few definitions out for a new-newbie?
Let me try…
Most of the USB AVR programmers out there are compatible with avrdude, the commandline tool you most probably want to use to flash your AVR controller. For these compatible ones you will probably need to install a driver under Windows, while this is not necessary if you are running Linux or MacOS.
However, a very nice looking USB AVR programmer, which comes in a rugged aluminum casing. These programmers do not need a separate driver under Windows, but they cannot be used from the popular avrdude. Instead these rely on a proprietary Windows software with possibly no future updates and poor support and documentation.
Yet, this particular USB AVR programmer is also based on the same basic circuit as the other programmers, which means that you can flash a new firmware and make it compatible with avrdude – however, this needs to be done with another AVR programmer…
So, if you could tell me, which programmer you ordered, I might be able to tell you whether you have to expect problems or not…
you can download the sources from here: http://wg65.de/avr/usbisp.zip
Uwezi ,
I am a victim of .bay too ………..not an usbasp at all .
before i reflash the unit , little question ;
Have you made a firmware based on thomas fischl’s firmware dated 2011-5-28 ??
Will that be possible ??
Hey newbee,
yesterday I re-flashed my ISP. The Board is dated 2013-03-15 and looks little different to the one published on this site, but the patch works as well. The only things I had to change was:
Change usbconfig.h as described by Shay:
#define USB_CFG_IOPORTNAME D
#define USB_CFG_DMINUS_BIT 3
#define USB_CFG_DPLUS_BIT 2
Bridge jumper 5 (on my board jumper ‘B’) to connect DMINUS on PD3
You can see the necessity when you take a look to the schema I found on google:
http://wiki.efihacks.com/images/f/fc/MX_USBISP_V3.00-schema.png
Regards,
Menzer
hi menzer
my Board is dated 2013-03-15.what do you mean “connect jumper ‘B’ to D-“?i mean short circuit 100ohm on dminus.is that true?
if yes it is forever or just for self prodramming?
thank you
mehdi
Hi mehdi,
when you compare the schema I found on the internet (http://wiki.efihacks.com/images/f/fc/MX_USBISP_V3.00-schema.png) with the schema from fischl you will see that this hard wire is required for USB communication. I is “forever” 😉
I did not use any resistor, just a blob of solder onto ‘B’, that’s it.
comparing two schema show that the blob of solder onto ‘B’ should be removed and PD2 should be connected to PB1.
what is your idea mr.menzer?
best regards
mehdi
Hi Menzer,
can you upload your hex file please?
yours sincerely
Juli
I suppose he did in his second comment. At least there are .hex files for the ATmega8 inside the zip-archive…
hi uwezi
my Board is dated 2013-03-15.inside the zip-archive exist two folder named (usbisp_2010-07-15_atmega8)and (usbisp.2008-11-26) and every one have main.hex
which is SUITABLE for my board?
The zip-file is not mine it’s just linked here. I also only have the 2012-05-20 boards as shown here, but I am not aware of any changes in the layout, user Menzer only commented that there was a different board date code out there, but not what the difference was. Since the zip-file is his, and he has the same board, then both of his versions should work for you.
Hi Menzer,
I have the same board as you. Flashing the hex from uwezi does provide me with a “usbasp fischl” programmer, but it does not work as expected.
Any chane you can post your hex file somehwere so that I can try an flash it?
I am new to all this microcontroller programming and still struggling in how to build my own hex file with the mods from shay.
Cheers
Axel
Hi Axel,
you can download the sources from here: http://wg65.de/avr/usbisp.zip
Thanks for this update!
I have not looked at or tried to modify any other firmware then the 2009-08-28 version from Thomas Fischl. I have contacted Thomas Fischl and informed him about the necessary changes, but never got a reply…
I assume that it should be as easily possible to modify the 2011-05-28 version of the firmware. I just had a look at the source code of the 2011-05-28 version. The definition of port D is found in main.c line 306-310. It is the exact same code as in the previous code version, however, I do not know if there are any other conflicting definitions in other parts of the code.
“hey – wait a second? All pins of port D are defined as output, except for PD2/INT0? I always tell my students to only define pins as output, which are really used as output… And what happens here?”
Oh god yes. Why do people make everything an output? It’s just begging for some unexpected connection or extra hardware causing a short and damaging the part.
In all my AVR code the very first step in main() is to make everything inputs and enable pull-ups. No floating pins (so no excessive CMOS current draw), no high current draw if something is connected to an input, and no floating inputs to any pins used as outputs to something else. Then modules can make only those pins outputs that are actually outputting something.
It’s surprising since the rest of the code is of a general high quality, with good modularity and no excessively-long source files.
“I will contact Thomas Fischl and tell him about this observation – perhaps the modification will be implemented in the distributed firmware on his homepage.”
Except that all the devices currently using the output-by-default code have the potential to be depending on this. e.g. the TX and RX pins are connected to the ICSP on some designs, and will thus be 0V with some decent current sink capability (less for TX since it has a 1K series). At this point it’s probably more risky to fix this than change it. Perhaps it could be a settable option that defaults to the old behavior, so in new designs it can be enabled and tested for specific hardware.
I had this same board and came up with a similar fix, but I also changed some usbconfig.h definitions to
#define USB_CFG_IOPORTNAME D
#define USB_CFG_DMINUS_BIT 3
#define USB_CFG_DPLUS_BIT 2
which I didn’t see mentioned in your post. I put a link to my code changes in the website link of this message.
IT WORKS 🙂
Programmer works perfectly with AVRDude and Eclipse.Big Thanks.
Thanks alot, now the little “USBASP” works fine with avrdude even in Jönköping 🙂
Hi!
Just wanted to say: Thanks a lot! Otherwise, I would have a useless usb programmer.
Regards,
Miha.
Life saver. Thanks for your hack.
Hello, i want to asking something..
whether this tool could be used for a minimum atmega AT89S52? I always find error..
please help me.. i’m a new comer
Have a look at the AVR freaks forum. There user newbie123 posted the necessary modifications for the configuration file of avrdude on Oct 18, 2010.
For those wondering what command to put into avrdude, this is it:
avrdude -c arduino -PCOM4 -b19200 -p m8 -v -U flash:w:”C:\Users\Owner\Desktop\20130212_mega8_usbisp.hex”:a -U lfuse:w:0xef:m -U hfuse:w:0xc9
You may need to change the PCOM to whatever number your arduino is (you find it on the bottom of the arduino programmer)
and you may need to change “Owner” to whatever name your username is
Thanks for the comment – but this is only relevant for someone who wants to use an Arduino to re-flash this programmer.
Hello Uwe Zi,
Used KKmulticopter flashtool and a Baite USBASP programmer to put your firmware on a MX-USBisp-V3.00. Works on first attempt!
Many thank,
Ray.
Hi,
I bought the same isp and felt into the same troubles.
Many Thanks for your tutorial, now I could make it works !
Hi, I have the identical chinese isp usp. Flashing with your hex file went fine and the led became blue. However, I got the error message:
avrdude: error: programm enable: target doesn’t answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
everytime I tried to upload using Arduino IDE. (My other USBasp worked fine.) Please, help!
Hi Hieu!
This is normal – it is normally the symptom if your programmer tries to send data too fast into the AVR.
Your other USBasp might have the external jumper which slows down the transfer rate. This newer firmware version supports a software command to slow down the transfer rate. In the command line options of avrdude please try to use the additional option -B 10 (that’s a CAPITAL B). If this works you can subsequently try to use lower numbers (the higher the number the lower the speed).
When I ran the command below, it seemed to work correctly.
Arduino IDE uses avrdude to upload sketches. I tried to google for how to configure Arduino IDE to pass the option -B 10 to avrdude. However, the only available option related to speed is “.upload.speed=” which specifies the baudrate. Any chances, you can show me how to set Arduino IDE to pass the B-flag to avrdude?
Sorry, but I do not use Arduino or the Arduino IDE.
But on the other hand, the “-B” option also just sets the “upload speed”. Possibly the Arduino IDE option does a similar thing – on the other hand it also possibly just sets the baudrate for serial-port programmers… You should ask this question in an Arduino forum!
I would guess that the option somehow can be set using the hidden preferences.txt file of the Arduino IDE, but it seems to be poorly documented and this is one reason why I never even considered using Arduino. Programming the same microcontrollers using GCC directly you are not bound by an obscure intermediate layer of software.
This is what avrdude does
-B 2 avrdude.exe: set SCK frequency to 375000 Hz
-B 3 avrdude.exe: set SCK frequency to 187500 Hz
-B 4 -"-
-B 5 -"-
-B 10 avrdude.exe: set SCK frequency to 93750 Hz
The SCK speed needs to be slower than 1/4 of the AVR’s current clock speed. This means for a brand new Atmega328 with a preset clock frequency of 1 MHz you need to use “-B 3” or higher.

Thank you a lot for taking your time to help me out. I have found out how to fix it. I just leave the link below in case someone also has the same problem.
http://forum.arduino.cc/index.php?topic=149668.msg1284514#msg1284514
I agree that with your point about arduino and I do feel restricted by arduino platform. I’m looking for books for beginners that teaches about programming AVR MCUs with C/Assembly (using ISP is prefered). I hope you can recommend me some good ones.
Hello,
I’m kinda new about microcontroller knowledge.
I’m searching an alternate ISP due to hard to find msp430’s chips (shipping from nearest supplier takes a whopping $40, too high when I want to buy only several(<10) for testing, buying the launchpad itself is cheaper :D)
So, Can I reprogram the firmware without any external programmer? Because you mentioned 'self-programming jumper'.
Or actually this can be solved with changing the HID? like this web: http://www.wortelsoft.nl/english/usbasp.html
Thanks
“self programming” may be a bit misguiding and actually leads to a chicken-and-egg problem. You need another working programmer to reprogram the programmer.
However, you can get a variety of AVR programmers on eBay where you do not need to do anything – these just work out of the box (or envelope when shipped from China). It’s only that this particular programmer has a nice aluminum shell which also protects it from short-circuits – essential if you want to give it to students in a project course 😎
Look for a programmer which either directly states that it is compatible with avrdude or one which is explicitly called USBasp. If you plan to use it yourself but want to protect it better then you can easily encase it with a strip of heat-shrink tubing to protect it from being short circuited by loose wires from your breadboard or alike.
The original firmware (HID) on the aluminum-cased programmer appears to be only supported by the Chinese software which you can download from the seller’s site. This has nothing to do with the driver for the USBasp which you will need additionally anyway.
In my case, I’ve bought two USBasps (same as in the article) and utilized Progisp (the Chinese software) to reprogram one another, using 1p-1p female to female wires. Now they work perfectly with avrdude too. Progisp is pretty simple to use, however, an english manual for it could be found here: http://www.1diycentre.com/Atmel_S51AVR_Programmer_USERguide.pdf
(*There is also a support for AVR_FIGHTER, but I haven’t tried it.)
Thanks for the answer.
I figured out the external programmer necessity after taking a little walk with Mr.Google and ended up ordering USBasp v2 by LCsoft which has 3.3/5v option (jumper setting).
I’ll see if I can tackle this hen-and-egg problem with these 2 as the lcsoft need a firmware upgrade too 😀
Program the aluminum-cased one first, then you can program the other one. I have done this procedure myself a couple of times now, because most of the USBasp clones from China are shipped with an old Firmware which does not allow the SCK speed setting from avrdude.
Don’t give up if you at first get a message about a problem which might be caused by the speed setting – in my experience with the old firmware you will succeed in about every third attempt at the default high SCK speed.
Thank you very much for everything!!
Because of you, it’s very easy. The hardest part was searching the correct jumper/wire diameter. In the end, I plucked several cores from stranded wires.
I also recommend this video for beginner as eepe is very easy if you’re not familiar with avrdude cmd line, http://www.youtube.com/watch?v=iHJwN7Z8QA4.
Just plug both end, follow the video instruction, and it’s done. No hassle at all.
Actually I normally use AVR Bunr-o-mat – even less command lining, since also the target device type is chosen from a drop-down menu.
Works perfectly, thank you for the tutorial!
Need Help…
How to set this programmer for low SCK? I need to set the fuse bit for New Chip/IC
What for M on the board? is this to set the mode?
This programmer does not have a hardware jumper. However, the software version which I put on this page but which originally stems from Thomas Fischl supports the -B option of avrdude to specify the ISP speed.
Thanks, I had already thrown the programmer in a corner marked as useless. It was quite a bummer when I found out that this programmer didn’t work with avrdude.
Hey just found this tutorial and I was also able to reprogram mine from USBHid to USBasp. (Red light to blue light!)
Thanks
Thank you very much for the .hex! Works with a device labled MX-USBISP-V3.00 2012-05-20.
I found that you can reprogram these with the unmodified fischl.de usbasp.atmega8.2009-02-28.hex or usbasp.atmega8.2011-05-28.hex firmware and they seem to work as far as I can tell.
The only change is on the back of the pcb have three solder bridges that need to be removed. These look kind of like a fork shaped solder bridges. Once these are removed then it should show up in Windows as a standard USBasp device, of course with one of the fischl.de images loaded.
See my post at http://arduino.cc/forum/index.php/topic,149668.msg1138408.html#msg1138408
for more details.
Actually: just modifying the source code once and then flashing the modified firmware is much faster than if I had to remove the solder bridges on all programmers for my students…
You are probably right as these bridges seem to make the connections to PORT D…
Uwe.
Hi
thanks a lot, I got it working last week compiling it myself.
THe only problem I have is that while it can correctly program an atmega328P, it seems it cannot program a an atmega328 (without P). The problem is not the usual signature issue (i.e. I run avrdude with -F). [I can programm the atmega328 with ArduinoISP, so the problem is not the chip]
I’d like to try the slow sck of aspusb, and I was wondering if you figured out where the SLOW SCK jumper should go in this “equivalent” programmer.
did you also get it working on attiny?
I just did an out of the box test on attiny45 and doesn’t seem to work… tried different -B options…
Hej Andrea,
I haven’t tested it on any ATtiny so far, but why should it not
work…
Just quickly connected an ATtiny85 to the programmer, wrote a small
“blinky” program, flashed it with “-B 10” and it works…
According to the verbose output of avrdude, the “-B 10” option results in an SCK frequency of 93750 Hz. I also tested with “-B 5” (187500 Hz), still works – my ATtiny runs on the internal 8 MHz oscillator at full speed.
Is your ATtiny possibly set for the internal 128 kHz oscillator? In that case you need to use an SCK frequency below 32kHz, e.g. “-B 30” or higher.
Uwe.
Hej Andrea,
I have already used it quite a lot to program ATmega16 and
ATmega168/328 without “P”. This version of the firmware actually
should support a software-setting of SCK rather than a jumper (I don’t
know if it still supports the jumper at all).
Try to use the -B option of avrdude, like “-B 10” to start with. My
standard setting is “-B 2”:
thanks it worked!
I used -i option, misunderstanding the help
Hi,
nice work.
I got the same programmer, could you post the hex file of the final firmware you flashed?
thanks
andrea
…yes, I can…
I can’t compile the firmware, give me tutorial please.
what the compiler are you use.?
I am using AVR GCC in WinAVR-20100110. I will upload the .hex file for the ATmega8-version here.
