32 x 32 RGB LED Matrix and Yun

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

Your code

I´ve read again Adafruit instructions and they make it very clear the fact that the library will work only with Arduino Uno or Mega…so I will work out another solutions. Many thanks for your reply
