PlatformIO Project

The USB Power Delivery for Arduino library is available via PlatformIO is as well. It can be used with a single lib_deps entry in platformio.ini:

lib_deps =
    manuelbl/USBPowerDelivery

Below is a more elaborate platformio.ini file. It supports multiple boards (select yours in the status bar of Visual Studio Code), and it enables serial output through the USB data line for the Bluepill and Blackpill board.
