Re: [avr-chat] Problem with motor control: Using ATmega32 + LS7290 + L298 stepper motor drivers.

[peruano4life]

I agree that the atmega only does steps but i think i am doing the steps
correctly or the motor i am using has some special properties built in that
only allow for applied motions drivers and not third party


i am trying to use applied motions HT23-597

thanks for any help
