Hello,
I want to hook up my board to the computer so I can have a debug console on my PC for my board. I want to use full-duplex UART for serial communications. My question is hooking up the USB-to-3V-TTL the way I have drawn enough? Or do I have to attach the RTS# and CTS# pins? What are the advantages of doing so? If I were to do it will I just hook them up to any free GPIO pins? Also can I get away with using this cable, it has only four pins (RX, TX, GND, and VCC). Thanks.
The cable drawn in the diagram is this one: link and here is the schematic for it: link
