No, bldc doesn't generate PWM, it generates amplitudes for a PWM generator based on measured rotor position. It might be possible, dependent on the IC, to use a single PWMgen to control the current, and to use the 6 bits to control the gates. (sending PWM to a master-enable pin, for example) The mesa three-phase-PWM generator generates 3 pwm phases on 6 pins in exact phase and with a deadband to prevent shoot-through. I have considered adding a 3pwmgen thread to bldc, but I think that the pwm frequency available in software would be rather too low for bldc use. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
