New Sparkfun RGB Matrix with Serial Backpack

Hi guys,

I was wondering if anyone might be able to help me with a problem I'm having with my RGB matrices. I have 4 of them in a daisy chain and they work great when displaying a static image.

However, when I attempt to display an animation there is some noise from other pixels that light up for a split second as the frame updates. I think this might have something to do with the way I have my SPI bus set up. These are the settings I am currently using:

(the clock needs to be under 125khz)

//SPI Bus setup SPCR = B01010011; SPSR = SPSR & B11111110;

Sorry guys, I would post this question in the sparkfun forums - but it seems that there is almost nobody looking at or posting on those forums.

Any help troubleshooting this would be greatly appreciated!
