ATMEGA32 interface with motor driver

[arvin444]

hey
i am using atmega32 to drive two DC motor(connected in parallel) forward and backward.
please tell about the interfacing circuit and IC needed to drive the two DC motors connected in parallell.
my PWM duty cycle is 10% for forward motion and 5% for reverse motion.
please help.....

you need L293D motor driver circuit and the rest is your programming skills for pwm...........

L293d can be used for driving two DC motors.Dont forget to add the capacitors to IC so that the microcontroller doesnt reset whenever motor reverses the direction.
For PWM i have used the Pins OCR1A and OCR1B. The phase correct pwm is used.
For more details look page 109 of atmega32 datasheet.
