hi,
I tried to use UART_TwoBoards_ComPolling example in stm32Cube. I know that this example is for communicating between two controller but i connected one controller's Tx and Rx pins to the ftdi chip that connected to pc with usb to observe what controller is sending. However,when i press the user botton on the board, pc seems like doesnt receive anything, tx and rx leds on ftdi also dont light up.
thanks

i used ftdi chip instead of second board and i tested ftdi chip before it was working correctly.
