Sorry, I misunderstood.

I coded the full-port-at-a-time method driver in assembly language as part of a 16F886 project and will test it on a prototype board sometime soon.

I also coded the Charlieplexed 20-LED MIBAM driver in an assembly language project for a 16F886 host.

Both projects simply have variables and the ISR driver setup for simulation so they're far from complete demos'. When I get something up-n'-runnin' I'll post a video and the assembly code, if anyone asks for it.
