Firmware

For advanced users, the firmware running on the Teensy can be modified and recompiled. All of the required files are within the firmware folder of this repo.

The firmware is developed for the Teensy using PlatformIO. This provides more flexibility than using the Arduino IDE (as is often used with Teensy and similar boards), but still allows use of the Teensy system's wide array of useful C++ libraries. It also avoids the increased complexities of utilising a proper embedded development environment (such as NXP's MCUXpresso for the Teensy 4.0's NXP RT1060 microcontroller).

Visual Studio Code is required for PlatformIO development.
