I'm starting a new thread for this issue.
I have the 2.8" Adafruit and am connecting it to an Arduino MegaPro. I have D0-D7 on the touchpanel connected to 22-29 on the MegaPro. The touch signals are connected. I have now the backlight powered with +5V. The control lines are connected so the C/D, CS, WR and RD signals connected to the appropriate analog pins on the Arduino. I'm still getting no picture. I have
a sketch that is supposed to draw to the screen. I'm still getting no output. It is just a white screen (backlit). Is there another way I can test the setup?
