Gentlemen:
I am working on a machine controller where the output is a string of pulses which are calculated at 4.1667 KHz from an external clock. The calculations take 60 microsec leaving 180 microsec of "lost" time. If a hardware interrupt could be used, some of the housekeeping duties could be performed in the 180 microsec of lost time. My tests using ON TIMER indicate that that interrupt works well, it's just too slow. I tried reprogramming the timer 0 but the results were unscuuessful. Now I need to somehow feed in the 4.1667 KHz as a hardware interrupt.
Does anyone have experience here? Working with assembler is just a little bit out of my league! Perhaps someone could direct me to information which woulld help.
Thanks,
Jack C.
