Can you use 2 PWM's simultaneously?

Another idea, even if not the best, having a 2XHPWM frequency, fed the HPWM output on a INT pin, enable the interrupt, and play with the duty in the Interupt handler... in my head it's working but i know i miss something in it....

OR create your own with a Timer interrupt.. but geez, a little bit more tricky if you really need it 100% stable.

Or, a double I2C DAC could be intereting... something like MAX518 if you can deal with a 8 bit resolution. They're not too cheap but great and simple to use.

There's still the Digital pot way, or, or ,or... man it's incredible how many ways you can do it )


What is the purpose of those PWMs?

EDIT: Darrel already done a SSPWM solution bellow but the frequency range is probably out of what you need

Hi Steve. The purpose is for motor control. I already made a circuit using the pulsout command. It works but, if I can have HPWM running the motors in the backround, it frees-up the PIC to do other things like checking battery voltage, turn on lights, monitor the motor FET's for shorts, etc. I've pretty much decided I'll have to use a 28 pin PIC such as 16F73.
