AT/PS2 Keybord - PIC Interface?

[BobPigford]

Thank you sougata,



I did allow enough time for the keyboard to start. I see the LEDs flash, so I think that is not the issue.

I will follow you suggestion and look into the buffer situation. I will also order a 40mhz oscillator just to be sure.

I will report back on my progress.

Thank you again,

I just isolated the issue! If I eliminate any output going TO the keyboard, everything works just fine! I disabled the "putkey" routine buy placing a "RETURN" immediately after the beginning of the routine.

Even with the internal oscillator at 8mhz, it all works very well (even with "TOcntDLY set back to 10)! I can live without seeing the LEDs on the keyboard for now. When my 40mhz oscillator arrives, it will try it again and report back.

Regards,
Bob
