A code to control embedded OLED display on ESP32C3 Mini

[AlexYeryomin]

I found ESP32-C3 Mini on AliExpress, a development board, which is equipped with OLED display, 0.42 inch, 72x40 pixels. This teeny tiny display could be convenient to show some measurements from the sensors like pressure or temperature, or, as I used it, to show the max altitude of the water rockets.

However, these displays are a little bit weird to control. Maybe it will be helpful for someone who faced issues with this board, here I wrote a sample code in Micropython:

Don't forget to install SH1106 driver for MicroPython.

Thanks for sharing! Very cute boards :D

As I mentioned, I used this ESP32-C3 to make a device to measure the max altitude (and the flight profile) of the water rockets. I put it into a small container, with the barometer, the gyroscope, the accelerometer, and, of course, a battery, then glued to the cap from a bottle. I can access the USB port on the uC to download the recoded telemetry or update the code. But the main idea is that I can see the max reached altitude immediately on landing to change the rocket's parameters for the next launch.

Very cool to see MicroPython in a rocket :D
