Use the potentiometer in InstaSPIN_BLDC project.

it's not controlSUITE code, but you can follow the idea from MotorWare

thank you Chris

I will see that.

Hello;
finally, I could how to use the potentiometer to change the motor speed.
But the system does not accepts a zero reference speed, the motor makes noise and vibration.
if I want to stop the motor, what parameter I can use apart from the reference speed.

you should probably disable the PWM until a valid speed for InstaSPIN-BLDC is given.

FYI, you can set a zero speed with InstaSPIN-FOC...

If I use the DRV830x EN_GATE pin, it will shut down gate driver block immediately, what do you think for this solution?

Hi Lamari,

Yes, this could work. Taking EN_GATE = LOW will disable the gate driver.

Hello Nicholas

I used the EN_GATE and the STOP button located on the KIT-DRV8301 as follows:

if(GpioDataRegs.GPADAT.bit.GPIO7==0)
{

GpioDataRegs.GPBCLEAR.bit.GPIO39 = 1;

}

if I press the STOP button the motor stops, but by releasing the button, the engine is always stopped, it is a problem for me, I want the engine running after loosening the stop boutton.

I did the same with the Enable FLAG:

if(GpioDataRegs.GPADAT.bit.GPIO7==0)
{
EnableFlag = 0;
}

it works, but it's the same problem, by releasing the button, the EnableFlag always remains at 0.
