Heello...

I'm trying to generate a 3-phase ~60Hz sine wave and i think it would be nice using any 16f7x7 with 3 CCP modules. The problem is that it will take a month to get these here where I live.

As I've been playing with 18f2550 @ 20MHz and got USB working really fine, I was trying to figure out if it is possible to create a windows interface to control a 3-phase sine wave.. then I would create sags, swells, harmonics and so...

The ideia is to control the 3-phase amp. and also its frequencys...(never exceeding ~62Hz..)

So, any ideias of where should I start figuring this out?

Is a RC low pass filter enought to generate a sine wave from a pic's pin pwm?

Well,, thanks for the attention!
