I've got an Adafruit 2.8" TFT resistive touchscreen I'm trying to get working w/ the graphicstest sketch (Arduino host is a new Zero--is that part of the issue right there?). The sketch compiles and seems to upload, the backlight of the display comes on, and this is the serial monitor output:
Code: Select all
ILI9341 Test!
Display Power Mode: 0xFF
MADCTL Mode: 0xFF
Pixel Format: 0xFF

Triangles (outline) 638626
Triangles (filled) 2035100

Done!
Any thoughts?
