I am trying to use a different LCD screen with the development board. This one use the standard 4 pin connector for its touch function (+X, +Y, -X, -Y), but I have an adapter which converts that to an I2C input. I tried using the PMOD connector to attach it, but am running into conflicts with the Linkserver connection for the probe. So, I would like to use Flexcomm3, which is (If I'm reading this correctly) part of the Arduino bus. How can I use Flexcomm3 for this device?
