AHT20 thermometer driver

2022-01-30 18 min read making code

I wrote a new driver for the AHT20 temperature and humidity sensor in Rust. This is a continuation of my Barometer build article, where I re-use the lps25_pressure_sensor_demo project to add a temperature sensor on the with_aht20_sensor branch. I’m a complete novice at Rust and embedded programming. These projects are my attempts to learn more about both while having fun and making something useful. You can find the driver at: Continue reading

Barometer build

2021-12-26 11 min read making code

I put together a barometer, built around Adafruit’s LPS25 breakout board, the Blue Pill microcontroller, and a small 16x2 character LCD panel. It was a learning project, and all of it was written in Rust. The finished project is a tangle of wires on a breadboard, and the error handling is minimal, but I definitely have a barometer with an LCD readout. You can get the code in my lps25_pressure_sensor_demo github repo. Continue reading
