Override board configuration

PlatformIO allows one to override some basic options (integer or string values) using More options in “platformio.ini” (Project Configuration File). Sometimes you need to do complex changes to default board manifest and extra PRE scripting work well here. See example below how to override default hardware VID/PIDs.

Warning

Due to a technical limitation these board changes will not work for pio device monitor command.

platformio.ini:

[env:uno]
platform = atmelavr
board = uno
framework = arduino
extra_scripts = pre:custon_hwids.py

custon_hwids.py:

Import("env")

board_config = env.BoardConfig()
# should be array of VID:PID pairs
board_config.update("build.hwids", [
  ["0x2341", "0x0243"],  # 1st pair
  ["0x2A03", "0x0043"],  # 2nd pair, etc.
])
