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
Does the STM32 USART TX connect to the FTDI RX ?
on issues like this ALWAYS, yes ALWAYS read the documentation, well, you should always do it, but here there is no 'standard'. there ARE instances where Rx connect to Rx (disagree with that labeling) I have seen it.
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 ?

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