Using a 32x16 LED matrix with Ethernet Shield

Other Hardware Displays
1

Hi everyone,

I've got a 32x16 RGB LED matrix and an ethernet shield attached to an Arduino mega.

I can get anything on to the LED fine and I can connect to a server to retrieve a value using the ethernet shield fine.

The problem comes when I try to do both of these at the same time. Calling ethernet.begin will stop anything being sent to the LED. I have changed all pins to use spare outputs on the mega board. It doesn't appear to be a memory issue either - freeMemory()=5533.

After ethernet.begin has been called, the arduino is still running through the loop and is outputting to serial.

Any thoughts on what could be going wrong?

Thanks
Jon
