[simpits-tech] Solid-state LED matrix help

Just wondering if anyone could offer some advice here. I scored an old Apollo 612b Loran a while back, to build into a generic GPS for X-Plane (since I can't see spending $5k+ on a nice KLN-94 to interface directly, though that would be awesome...) Handily, the dual-concentric rotary encoder, push buttons, LED matrix panels, and LED annunciators are all on their own easily-detached panel. Interfacing the encoder, buttons, and annuciators should be fairly straighforward, but I'm stuck on the solid-state LED matrices.

This seems to be what I have:

Specifically, mine is the QDSP-2007. Unfortunately I have pretty much zero experience when it comes to making microcontrollers and writing assembly code, but it sounds like this may be fairly straightforward (if a bit tedious to actually use) for someone with a little more experience to wire up.

Does anyone know of an existing microcontroller card of some sort that would talk to this little guy? Is it something an Arduino might be able to drive without any special intermediary circuits (just using the data pins)?

If anyone could offer advice or just point me in the right direction, I would appreciate it. My next plan is to hack one of those little 1.5" keychain photo frames (already found a solution for this that will probably work OK) and put it in place of the matrices, but they sure do have a cool retro appeal. Even if I stick with the 1.5" photo frame, it would be nice to use the LED matrices somewhere else.

Thanks!

Matt
