Configuring GPIO 14 on Rpi3 I've currently configured my Rpi for serial communication, and I can successfully receive serial data from my device to the Rx pin of my pi. My question is: Can I configure GPIO pin 14 on the Rpi (which is the Tx pin for serial, which I am not using) for general purpose I/O **AND** continue to use my Rx pin on the pi for serial communication? I'm running short on GPIO pins and this would make my life much easier.
