H, I have Adafruit 32 x 32 RGB Matrix Display connected to an Arduino UNO as per this instructions and everything works fine.
In order to be able to access the internet I replaced the Uno by an Arduino Yun and the display doesn't work anymore. I suspect there is some pin conflict but I wasn't able to find out how to fix it.
I have posted the problem into Adafruit but got no answer.
Any hints as what could be wrong?
Many thanks in advance
