Micro:bit v2 :MOVE Robot Firmware

The application is located in the zephyrproject/app directory. It is designed to run on the Zephyr RTOS and is compatible with micro:bit v2 hardware.

General board info can be found here.

While there is existing documentation on the MicroPython libraries for the micro:bit and Kitronik :MOVE, this firmware provides a more direct interface to the hardware. Check out this wiki for the MicroPython extension documentation, our implementations are loosely based on it.

Usage:

1. Cd into the zephyrproject/app directory.
2. Use the west tool to build and flash the application:

   west build -b bbc_microbit_v2 app
   west flash

3. To monitor the application output, use:

   screen /dev/ttyACM0 115200

   Ensure that the serial port matches your system's configuration. You can use Ctrl+A then \ to exit the screen session. You can use -L to enable logging into a file.
