Unstable sine PWM output

[ScaleRobotics]

Thanks Henrik! That's good to know! I knew the N-Bit for multiplication would be slow (doesn't utilize hardware multiplier), but did not think that division would be very different.

Thanks for the info!

Of course I'm keeping DIV32, and I've modified the TMR1 prescaler to 1/2, now I really have 1.0Hz at the min. frequency (and I still keep a good accuracy at high frequencies).

The project will be posted in one or two weeks.
