Hi all,
I am using F28027F @60MHz cpu, 20kHz PWM - that gives 3000 cpu cycles (asymmetric PWM) and 1500 cpu cycles (symmetric PWM) resolution per PWM period. This can only utilize ~10bits of PWM resolution.
I wish to test asymmetric PWMs for its benefic of doubling timer's resolution for reduced ripple in winding currents by modifiying Motorware. I had succesfully setup the PWM to output asymmetric PWMs but have no luck driving my motor with both rising- & falling-edge aligned PWM outputs.
My question is besides changing the PWM, what else do I need to modify to make MotorWare runs on asymetric PWMs?
