I found the command code and the values needed to access and change colors on the 4 LEDs on this display.
Using suggestions from _X7JAY7X_, poring over code from CF and from other plugins, and playing around with CF's utilities, I got it blocked out rough what I want it to do using 5 functions (1 for each LED and 1 to turn off a specified LED). I'll clean up and actually fix the syntax of the functions when I get home, but I think I'm on a fool's errand...
The problem I've hit is I can't figure a way to get Smartie to send a command packet to a crystalfontz display. This means I'd have to build something to send out the packet directly from my dll (which I'm not even sure can be done), and that is way out of my league. I looked at the code CF uses in the wintest app to do that, but it's written in C, and doesn't make much sense to me.

I'm going to keep plugging at it and see what I can figure out; I appreciate any input, however; This is mostly for myself so it's not a huge priority, but I know others were asking about such a thing so it would be nice if we can get it to work.
