Hi,
I was wondering if the RTS and CTS lines can be left floating/ unconnected on an FTDI cable or should they be connected to GPIOs on my MCU? The reason why I want to use an FTDI cable is more for the RX, and TX lines to program my device.
In addition, I read that the VCC line (red wire) is 5V I'm assuming that this 5V is supplying from the cable to the board, and thus can also be left unconnected? The cable I found is http://www.digikey.ca/product-detail/en/TTL-232R-3V3/768-1015-ND/1836393.
That's because the device I have is a battery powered device (3.3V) and I don't want to damage anything in the process, so I'm mostly looking for some confirmation to be safe, since I haven't used one of these before.
Thanks in advance for the help!
