Hi
I received a 32x32 RGB LED Panel from Adafruit and wanted to connect it to a YUN to receive the information to display from the web.
I tried first with a 8x8 LED matrix and everything was working fine.
Then I connected the 32x32 panel to the YUN and nothing worked. I did not received the result the test sketches should show, only some LED lightning up. I renewed the wires two times and also reset the YUN twice. Still no solution.
Now I connected the matrix to a Arduino MEGA and everything was working immediatly.
See videos.

The sketch is very easy, see attachment.
Any idea what is wrong on the YUN?
Thanks for you help.
Regards
Ralf
