The last time I used this TFT screen, I found some problems. Thankfully, since I worked through them once, I had some experience to help this time around. My notes told me that this screen used the SPI protocol, not I2C, so I was using the wrong pins again. I probably checked my connections a dozen times while I tried to figure out why I couldn't get an image on the screen, but I saw something when I hit RESET on the Arduino, so I knew the monitor was getting data.
I hypothesized that my problem was sending 5V signals even though I supplied the board with the required 3.3V. I planned to connect a level-adapting board, but I tried providing the monitor with 5V, and everything worked. I used one of my previous functions to display the current number from the demo mode.
