"This is not an officially supported Google product"

This project uses two build systems, PlatformIO and CMake. PIO is for code which runs on embedded devices - these run the actual hardware. CMake is for running tests on standard PCs.

To build with PlatformIO, run pio run -e , where is one defined in platformio.ini (e.g. teensy`).
