matchy:
I purchased a 1.8" (got working) and this 2.2" tft display from eBay. I haven't been able to get this 2.2" display to work either. Although I tried it but no luck, that if 3V is required, can it be done with mega?
?? Arduino Mega? Also on Arduino Mega signals on pins are at 5V.
Arduino Uno and Mega have a pin at 3.3V but all other pins are at 5V.
