Concept board RX pin as GPIO | Thales IoT Developer Community

February 27, 2018 - 6:39am, 1396 views

I'm using an external shield that need to be turned on by sending a signal to the Arduino D0/RX pin connector. I find that the Concept board documentation (Hardware Interface Description document) section 1.1 "Key Features at a Glance" shows UART/GPIO, but no mention of switching to GPIO in the following pages. Is it possible to use this RX pin as GPIO programmatically? How?
