Hello, I used the official motor drive example and found that the calibration time varies. Normally, the time is about 2 seconds,
Added a judgment statement on motor1CtrlISR, with a calibration time of 3 seconds. Why is this

    Hello,

    Apologies, I don't understand exactly what is being asked. A couple clarifying questions:

    1. From what you wrote, it is my understanding that you've added a function to the ISR that measures how long something takes, Is that correct?
    2. What do you mean when you say 'calibration' ? There are several phases to motor startup, for example, but none of them are named calibration. Do you mean the motor alignment phase?

    Regards,

    Hello, it's ADC calibration,
    runMotor1OffsetsCalculation(motorHandle_M1);
    I am on __interrupt void motor1CtrlISR (void)
    Added a function to wait for ADC calibration to complete and send PWM waves, but found
    RunMotor1Offsets Calculation has become longer, why is this
