    Default Re: sinusoidal PWM

    The max I see most people do is a 72 step lookup or array. (36 or 72 steps makes it easier to off set for multiple phases). The resistor capacitor filter smooths out the steps. It is still 8 bit resolution, even with 32 or 36 steps. If you wanted to have each value be more accurate, you could use 10 bits in your values for each step.
