Hi, I want to conect an external MCU to the STM32F746 DISCO using UART but I dont know how to use another UART other than the one used for communication with the PC.

Hello @ferdlf

As said @Andrew Neil, all UARTs work almost the same. I suggest you to take a look at this example to understand how it should be configured.

Best Regards.

It's used just the same as the one for communication with the PC.

You allocate available IO pins, and then connect those pins to the other MCU.
