STM32G484, RS-485 and Modbus - how to configure in CubeMX???

When you configure a USART for the STM32G484 in CubeMX, it gives you a choice of RS485 or Modbus (but not both!). Yet, Modbus RTU runs *on top of* RS485, so this makes no sense. The Modbus configuration appears to put the MCU USART into half-duplex m...

Autogenerated files breaks the build.

After upgrading the IDE to version 1.5.1 within the eclipse IDE, the CubeMX built in tool auto generates this file. This conflicts with the one in src (same function is defined in both places). I had to temporarily exclude the folder from build for ...
