Question

STM32L433 - LPUART1 wrong baudrate

Hello,

I'm using STM32L433RCT-P nucleo board and I was testing some hardware. I noticed the baudrate error with LPUART1 is really high (135100 instead of 115200, 67570 instead of 57600).

I have no problem using manual configuration instead of CubeMX, but, is there a way to obtain the chosen baudrate directly from CubeMX?

Thanks!

In another clean project works better (don't know why because in the other one all i did was sending on lpuart 0x55). Still a bit off though.
