        Overview of how to write test firmware for a custom STM32-based PCB, in particular for a variant of one made using the hardware design tutorial videos (including various sensors, flash memory, USB, etc.).<br><br>

Includes topics such as: STM32CubeIDE, SWD and ST-Link, Timers and PWM (RGB LED), USB (Virtual COM Port), SPI (driver for inertial measurement unit).
By no means a complete tutorial but rather a guide on how to approach writing firmware when you first get your custom boards!
