Hi all,

I need to drive 3 phase inductive motor, so I find IR2131 for driver. My question is: I neeed 3 PWM channels from Atmega 128, and I will use for that OC1A, OC1B, OC1C for that, is it ok?

Thanks in advance,

You might want to look at AT90PWM3, and the reference material for it (demo kit, app notes AVR494/AVR495, etc.).

There is also that open motor drive project that I can't think of the name.

I was seen that but I wont to do that with Atmega128 becouse it's on universal board and I need to prepare free pins for 3 phase drive...
