Look at this.
4 Mhz => 1 Mhz machine frequency => 1 us per instruccion. Using TMR0 overflow as interruption for determinate high time/low time, we have 255 cicle at 1 us => 255 us witdh pulse ==> fpwm=1/T = 1/255us => 3,921 Khz pwm......
But the question is....how does work the shift register to set the duty cicle value....

Hello,
Sorry but that PS was not good. It was too slow responding and had noise in it. I have discarded the code and I have
nothing left for it.
I have rebuilt it with analog 723 chips.
Regards, Jacques

Unfortunately, I do not know how slow responding is and how many noise is in the output but te project is still very attractive...
