Part Number: DRV8302-HC-C2-KIT

Hi everyone,

I have been trying to implement this Emergency Stop Switch  and I am not exactly sure how to go about it. I would need to have 2 of them hooked up to the board and whenever it is activated, I need the everything turned off. Any suggestions on how to do it?

Thanks in advance

    You might use a GPIO as a switch, and run/stop the motor by checking its state in a PWM ISR to stop the motor by disabling the PWM output or motor control function. You can also configure this GPIO to a trip zone if the using GPIO support TZ function, so the PWM will be turned off to stop the motor.
