Re: Mega Discrepancy?

Got it working now. For further reference:
Two things needed:
1. Uncomment USE_UNO_SHIELD_ON_MEGA in HW_Atmega1280.h
2. Change UTFT myGLCD(ITDB24E_8, 19, 18, 17, 16); to UTFT myGLCD(ITDB24E_8, A5, A4, A3, A2);

Re: Mega Discrepancy?

Does the Sparkfun Mega Pro use different CPU pins to the corresponding digital and analog pins than the Arduino Mega? If so, that'd explain the discrepancy. Anyone knows?

Re: Mega Discrepancy?

Well, apart from the above mentioned difference between 3,3 and 5V pins, the pin mappings are identical regading the pins used by the display.

Mega Discrepancy?

Hi All, I've got this display: http://www.electrokit.com/2-4-tft-lcd-touch-shield-for-arduino.49420 It's working on Standard UNO (5V) but just lit up on the Sparkfun Mega Pro (http://www.electrokit.com/mega-pro-5v-arduinokompatibelt.49198). I've cut the 3,3V feed as it is connected to 5V on Sparkfun...
