Menno :

What do you actually want to make? Is it 3 phase-shifted sine-waves?

Yes, thats precisely what I am trying to do with the RD2. I looked through the PCA cookbook and found a way to generate a PWM, but to time it is something I have not got a clue.

Assuming I want to construct the waves with 16 or 32 samples, how to time the samples to coincide in such a way as to not cause a glitch?

Any clues?

Thanks for your time and inputs. I really appreciate it
