Posted on May 17, 2011 at 10:20first off all you must use single pwm channel to drive power mosfet with a mosfet predriver. ifyou want control direction another output pin can be arranged for direction information. in that case you must use a hbridge dc motor power circuitry.if you want control mmotor torque adaptively you can add a resistor between ground and mosfet. and you connect that pin wit a suitable current sense amplifier circuitry to adc input of mcu. you ccan change pwm freq according to current across on motor.
there a a lot of simple aplication codes at section examples library adc and pwm. you can adapt that codes for your aplication.
