Anyone have experience with the 16F77?

[Jon Wilder]

Jon Wilder-

This page has PIC bitbang send and receive, they are in C but the principle is easy to understand (and convert to asm) and a clever TMR1 timing trick is shown for the serial period;
Bit bang serial - PIC 18F1320

These pages should be of interest to you, it's a minimal MIDI-out drums controller using a PIC 16F and just 2 resistors;
MIDIbash project concept
MIDIbash 2 with PIC source code
The second link has PIC source code where the MIDI-out code is bit banged and done in assembler.

Thanks for those! I completely understand what's going on now!

On another note I think I'm gonna go with the 16F887 instead of the 16F77. Looks like it has the same stuff as the 77 but at 1/2 the cost.

Mike I will be ordering up some of those serial driver ICs. Gonna have a few places I can use them in this particular device.
