Hi Tiss,

1)Are you using a PIC with 3 or more internal pwm??
2)Do you want the PWM to work in the background?


if your answer to the questions were YES then I suggest you use PIC16F777. REASON for this is 16f777 has 3 internal pwm and it;s very simple to implement. even a little kid can do it.

MISTER_E was/is an excellent tutor at this. Very useful person


if your answer to one of the two questions was no. then I suggest just doing it all in software. that is also very simple.

MISTER_E is again a very useful person at this.
==============================================

I can help you out if mister_e is busy..... let me konw tissy
