“I've only used the display functions so far, with an Arduino Uno, and they worked straightaway (unlike a couple of other displays I've tried). One oddity I have found is that, having written and debugged code for a different display (SSD1306), and ported it for this display, the communication with the Arduino IDE stopped working (apart from upload). I discovered that, although I had set my Arduino serial link for a 9600 baud connection, running the display intialisation function changed it to 115200 baud. Once I changed the Arduino IDE monitor to 115200 then everything worked as I expected. I'll post more when I've tried the touch side of things.”
