Re: Bug in F3 USARTv2 BRR calculation
I did some investigation, seems like the clocks are being calculated incorrectly indeed. USART1, as shown in the clock tree at page 128 of the reference manual (ST document RM0316) for the STM32F303x6/8, is the only USART module that has a selectable clock (you can also see that in the table at page...

Bug in F3 USARTv2 BRR calculation
Hello, I'm on ChibiOS 18.2.1, STM32F3 (the F303K8 Nucleo-32 to be precise, shouldn't be relevant) and I found out that if I change the STM32_PPRE2 from STM32_PPRE2_DIV2 to STM32_PPRE2_DIV1, USART1 (using the Serial driver) runs at half the baudrate (0.51 times the desired baudrate, to be precise). S...
