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?
