Peter,

Could you give us a bit more detail on your design, like
- Does the PIC have to deal with other things apart from the sine waves ?
- How accurate do the sine waves need to be (PWM frequencies, resolution) ?
- Must it be a small device ?
- Price ?

Cheers,
-Andries

Subject: [PIC] Gen 3 sinewaves with 120 degree difference
=20
Can anyone please advise the most efficient way to program a PIC to output=
=20
three simultaneous 8Hz sinewave outputs with a 0, 120, 240 degree phase=20
relationship? The object is to apply the waves to coils to produce a=20
circularly polarized field. I understand the PWM outputs will need to be=20
filtered to derive the SW's.

Any pointers in this direction would be sincerely appreciated. Or, if=20
someone can program this with their existing expertise, I would consider=20
paying for the service.
