Example of using a 3x3 matrix of ST-00050 8x8 LED display modules

I thought I would post an example of using a 3x3 matrix of ST-00050 RGB LED display modules. Unfortunately the ST-00050 modules are no longer available, but they do work very well in creating (in this case) a 24x24 pixel display with vibrant colors.
The following video link shows the 3x3 matrix of LED display modules in action, showing an animated 24x24 pixel Pumpkin/Jack-O-Lantern:

I've attached a zip file containing the program and drivers that I used to do the above animated image.
A 24x24 pixel image normally would need 576 longs to describe each RGB (BGR when using these modules) pixel/led. In order to save space I created a DAT data structure that allows you to just specify the Column, Row Start-Stop and BGR value. This significantly reduced the amount of storage space needed to hold the data, but still have good read/write performance when sending the data to the LED matrix.
I'm using a Propeller proto-board to run the program and serially send the commands/data to the 3x3 matrix of modules.
If anyone else has ST-00050 RGB LED display module examples, I would enjoy seeing them.
Have a HAPPY HALLOWEEN...

Merry Christmas
All the ST modules are still using the factory firmware.
