More on the Funky Clock

I had another one of the LED arrays around the place and decided to see if I could drive it directly from the PIC port pins.  It seems I can, and the results are much better than my much more complicated previous setup.  Of course it uses up almost all of the PIC18F4550’s port pins.  All of port A, B, D and E 😉

The thing I was really happy about was that the code I had written for the old hardware needed very little changes to work.  Forth is really good like that.  All I had to do was change the low level code that actually hits the hardware, and the higher level stuff just worked 🙂
