Electronic variable vane control

I did end up changing the dsPIC into an 18F series, since I didn't really want to deal with logic translations between 3.3v and 5v. I'm pretty sure 12MIPS at 48MHz should be enough to read from a serial bus and position sensor and set the vane position. My actuator is driven by a motor with reducing gears directly to the vanes, so its pretty simple to control with a H-bridge.
I don't really make schematics when I'm laying stuff out, just tend to do the PCB from chip pinouts, so none are avaliable. I'll post software whenever I get the whole system built, as right now, its just bits of code here and there that I can't finish until I have the boards to debug it on. If anyone else plans on using a PIC microcontroller, I have about 5 years experience working in MPLAB C18.

1981 Mercedes-Benz 300SD | 156K Miles | 2nd Owner | EGR Disabled [Removal Pending] | ALDA Removed | Straight Pipes | GT2256V??? | Laser Interceptor | Engine swap over summer, hopefully with GT2256V attached...
1981 Mercedes-Benz 300SD | Odo Stopped at 160K (at least 50K more) | EGR Disabled | ALDA All The Way Out | Straight pipes | FM-870 Remote Start Alarm System | B100 Biodiesel | AC Fixed x2 | Trunk crushed in
| Retired to garage.Excessive speeding? It ain't excessive till I redline!
Heres my finalized motor control board, http://img6.imageshack.us/img6/6163/50120720.png
