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
yes sir, in that example there is read_me.txt file that shows connections rx to tx,tx to rx. I think the problem is on board ,it doesnt send data through tx.Did you try that example code before,it worked ?
