Well, heh.. here is what I have in mind.
The 1, 2, 3, 4 and enable lines are all pulse width modulated by the AVR. The filters after the gates convert the digital pulses to an analog voltage. The idea being that the MOSFETs are smoothly driven from saturation to cutoff, instead of just slammed on and off. The only reason I'm considering the filtering is because I've got to reduce noise and get the motor to run as smoothly as possible. I'm hoping I'm not totally off my rocker here...
Please let me know what you think guys! |
