Hello all,

I have no idea how to calculate usart "% error calculation" for stm32f429. There is difference between *actual baud rate *and *desired baud rate*. Why *actual baud rate* != *desired baud rate?*

I try to calculate usart % of error for 90mhz. The last calculation in documentation is for 84mhz (see attach).

thanks in advance

Calculating the

erroris easy - it's just the difference between youractualbaud rate, and thedesiredbaud rate.I guess you really mean how to calculate the

actualbaud rate?
