Timing of the internal analog-to-digital converter of an ATmega328P with a 5 V supply voltage.
ATmega328P - measuring its own supply voltage III
[latexpage] After the first two parts of this series ATmega328P – measuring its own supply voltage ATmega328P – measuring its own supply voltage II where I investigated the possibility of…
A simple yet versatile testcircuit for the analod-to-digital converter.
ATmega328P - measuring its own supply voltage II
[latexpage] Here is a brief follow up from yesterday's post on the internal reference voltage VBG of the ATmega328P. I wrote a small test program where I wait for a…

ATmega328P - measuring its own supply voltage
[latexpage] The trick is not new, it is utilized in the AVR transistor tester which you can buy for quite cheap money from China, and it has been discussed in…
Bitmapped math in XeLaTeX output.
XeTeX and your math is bitmapped?
I have now been using XeLaTex exclusively for quite a while for all my LaTeX work, which essentially means for everything: lecture notes, lecture slides, lab instructions, letters, reports,... For…
