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

[Eric Pasquier]

Hi,

I thought you were driving the MOS FET directly from the ATMega32, but no,
the LS7289 is doing everything
How can the ATmega can burned out the ICs ?  you only have access to Step
and Direction .

Eric.

a solution for this?

looking for help


thank you
