Baud rate problem

[bngstskn]

Hi, I am using STM32F767ZI. I am working on UART communication of STM32F and other MCU. But I have a problem. Other MCU 's baud rate is 125K, 250K and 1M. Do you have any suggestions about this? Thanks to answer.

Hi @bengisu taşkın​ ,

It should not be a problem, the STM32F7 supports a baud rate up to 27 Mbit/s when the USART clock source is system clock frequency (max is 216 MHz) and oversampling by 8 is used. 

Increasing your system clock frequency should solve your issue.

Please refer to the attached datasheet Section : " 3.25 Universal synchronous/asynchronous receiver transmitters (USART)" for more details.

And what's the Problem?

​

Are you generating the wrong rates?

What vs what?

Bus clocking fast enough​?

Code handles rate adequately?

HSE_VALUE reflective of clock board uses?​
