STM32F103 vs GD32F103 round 3: UART

Here’s the part 3 of Sjaak’s post comparing the GD32 to the STM32:

Since the GD32F103 can run as fast as 108MHz but has not a proper USB clock divider to provide a 48MHz clock for USB communication we need another way to communicate with the outside world. Since the early days of computing the easiest way to go is a asynchronous serial interface using the UART peripheral. I can try to explain how this protocol works, but here is a better write-up.

If you missed part 1 and part 2, be sure to check it out.
