Hey i often visit the picbasic.co.uk forum.

There is a guy named DARREL TAYLER and he really rocks on picbasic pro !!

Check out his site http://www.pbpgroup.com/

And in specific the Multi SPWM item.

He designed a full add in wich can run multiple pwm's simultaniously on slow speed.

50Hz is ok with this program.

Hi,
I made a sine-wave inverter with PIC16F876A, with one PWM and direction signal,
with H-Bridge.
Circuits and software (writed in CCS PCWH) are here:

Hi,
I know the question relates to a PIC16F877 but would suggest you might have a look a the 18F series such as the PIC18F2331. These have three identical PWM generators that are designed to work together to produce phase related waveforms. I don't think there is much difference in price any more.
