CapTouch with MEGA2560 not working

Post by captainkirk »

I have the 2.8" TFT LCD shield with cap touch. v2.3
I've shorted the SCL and SDA jumpers. (and the jumper/cuts to use the ISCP port)
Trying to get it working on an Arduino Mega 2560.
The display works, but I can't get the CapTouch Paint example to run.
("Couldn't start FT6206 touchscreen controller")
The display just shows some very fine (1 pixel wide?) gray/white strips.

On an old Duemilanove CapTouch Paint works just fine.

So it seems the board is fine, just doesn't like the Mega.
Any suggestions? Thanks!

Image shows the setup that works for me: only ICSP pads were soldered. 11-13 traces were _not cut and nothing was done to SCL, SDA.
