Hello! Have some problem with UART on STM Nucleo L476RG. We need to transmit bytes from Nucleo to Raspberry (needed to output in program on Raspberry count-speed; it depends on frequency on Nucleo, that we want to transmit from Nucleo to Raspberry).

But it doesn't work (though we can transmit (write() raspberry function) bytes from Raspberry to Nucleo; and we have similar sample of read() function).

So can you help with this problem?

Hello,

Have a look to the UART example available in the STM32CubeL4 firmware package to help you on UART use and initialization.

Kind Regards
