Hi

I want to use the baud rate to 921600 in stm32f405vgt6.

Can I use 921600 in UART1 ~ 6?

And Is the error rate to zero?

Thank you.

you can set it hand.

Same as in terminal 1 b software.

Have you tried it?

That of course depends on the respective APB clock, which in turn depends on AHB clock.

> And Is the error rate to zero?

If that's your priority, use a crystal frequency of which is multiple of 921600, e.g. 7.3728MHz.
