Atmel Microchip Studio

1 1/2 years ago now I have finally abandoned Microchip (Atmel) Studio for programming AVR microcontrollers.

I have been using Atmel Studio from the very first day I have been programming AVR microcontrollers and I have been following it through the version 4 to 7. But already a couple of years […]

We need to talk about ChatGPT

There are other, more detailed analyses, looking behind the curtains of ChatGPT, this is just a short summary of my own experiences. For more details, look e.g. here: ChatGPT: Interacting via a conversational way!

ChatGPT is this (in)famous artificial intelligence which has been all over the media lately. It describes itself as a language […]

The TIAN MA A2C00096100 LCD

The electronics distributor https://www.pollin.de/ is often selling surplus displays, but normally these are not very well documented. The TIAN MA A2C00096100  LCD module is a 90 mm x 20 mm character display with on-board chip-on-glass controller. It has 20 alphanumeric character positions, actually 18+2 since there is a vertical 1-pixel wide bar separating the […]

Nicely rendered 7-segment numbers

User cbm80amiga has uploaded a nice library to render 7-segment numbers on graphical displays – especially for Arduinos. But the code can as well be used without any Arduino in the proximity, just a slight change in the library made it an universal C++ object.

It had the ambition to follow up with further […]

Temperature measurements with an NTC thermistor

sagecell.makeSagecell({“inputLocation”: “.sage”}); Following a discussion on Facebook I put here an online tool to calculate the output of a voltage divider consisting of a fixed resistor and an NTC thermistor following a first order Steinhart–Hart equation.

The calculations are based on a voltage divider where either the voltage over the NTC or over […]

Canvas: Using Python to create Calculated Questions

Background

I just recently started with Canvas because Uppsala University has decided to use it as its upcoming LMS platform after a failed attempt with another product. Therefore I had already spent some time with Blackboard and was quite fond of the calculated questions type in quizzes. I quickly found out that Canvas offers […]
