The distinction between Serial and Serial1 is really good news! That may solve my problem.
I would gladly take advice on which library to use! That is how new I am to this business. The library I am looking at is Elegoo_TFTLCD which came on a CD packaged with the touchscreen. Header file attached in case it is not readily available to you. I wonder if this software is fundamentally identical to the TFTLCD library provided by Adafruit.
Additional question: that library contains the constructor
Elegoo_TFTLCD(uint8_t cs, uint8_t cd, uint8_t wr, uint8_t rd, uint8_t rst);
Can you give me some insight on what to put in those five parameters? It looks like they specify control lines, I am not clear on where to specify what lines are used for data.
