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 🙂
That looks very promising Daniel.
I must have a play with your Forth on a SUM board.
