Dear reader,

I am a near beginner in c# (visual studio). I've written myself a PWM generator which controlls the parallel port. I can change frequency, dutycycle and stepsize. The problem is as follows:

I'm generating PWM in a while(true) loop in a second threat. This is the only way i know how to generate accurate PWM cycles. The only problem here is that i don't effectively use CPU time(im burning 50% time). I want the following:

/pseudo code on/

tell windows or some eventwatcher that i want to wait X cpu ticks
IF they passed, give an interrupt or jump to some codeloop
(without endlessly waiting and burning cpu cycles)

/pseudo code off/

In fact, system.timer or so has a timer that jumps on every set timertick to a loop. This is exactly what i want but more precisie than 1 ms. I want microsecond accuracy with autojumps to a function after a given time. Can anyone tell me how to do this in code? I will paste my code if you guys want it but this is all there is to it.

Thanks,
Bas Kapteijn
