Setting up the microcontrollers
To test the microcontrollers, open up Thonny and use the hamburger menu in the bottom right menu to select MicroPython (ESP32) while the board is plugged in. If it doesn't bring up a REPL prompt, you'll need to install MicroPython on the unit
Installing Micropython
A tutorial for installing MicroPython is available at the MicroPython website. Thonny will tell you what port the device is connected on, but you'll need to close it before you use the ESPTool program. You can run both commands at the same time via the following:
esptool erase_flash & esptool –baud 460800 write_flash 0 ESP32_GENERIC_C3-20250911-v1.26.1.bin
Uploding Code
Plug the device in, and connect to it via Thonny. Use the View tab to check the Files option. Copy the main.py file to the device, create (and enter) a lib folder on it, and then upload functools.py to the folder. Connect the sensor and run the main.py code to check if it works, it should output a message saying addresses found:0x10 and then start streaming data.
Setting up PCs
Computers will need to have tkintertable and pyserial-py packages installed. The rest should be part of a default anaconda install.
