STM32F0 UART Single Wire Half Duplex - Incorrect initialisation code

Andrew Neil · ‎2023-08-04

The initialisation code generated (by CubeIDE v1.13.0) leaves both the transmitter and the receiver enabled!
This is clearly not a valid state!

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Same problem here - with STM32C011:
