Request support for GENERIC STM32G4 mcu's. #711

Open darkomenz opened 1 year ago

darkomenz commented 1 year ago

Hello Team,

Can we add support for the STM32G4 line of MCU's? No generic board profiles seem to exist for these at this time.

Regards

It looks like this is ok by now:

$ pio boards g4

@jcw I see only one generic stm32g4 listed. There are many more in the product range.

It's not hard to support other variants:

  1. fetch and rename https://github.com/platformio/platform-ststm32/blob/master/boards/genericSTM32G431CB.json
  2. adjust info to match you project's requirements
  3. place it in a boards/ directory inside your project
