AVR based intelligent LED display

This 8x8 bicolor display produces red, green, and yellow pixels. It is custom made, using an Atmega8 AVR and TLC5920 LED Driver. Coded in C, all the effects you see are based on frames. The display is double buffered such that frames can be edited while the screen continues to animate, also if some or all steps of a transition take too long, the double buffering prevents screen flicker.
Frames are retained even when using transitions, such that looping effects with few numbers of frames is very easy. Larger animations can be done by streaming from a host PC or microcontroller, or natively by loading them from memory as it animates.

I am trying to drive a TLC5920 for one of my projects but am having trouble getting it to latch properly, is there any chance you could help me out (with advice or code snippets)? like the display btw, very expandable too with that particular matrix driver
