Hi,

 I have a phenomenon. when I enable Realtime Options (Halt the target before any debugger access) on Code Composer Studio , The F28035 responded to Motor  control too late . Then , the motor control have noise and un-control .

   How can I read data on realtime and DCU work fine with motor ???

Regards,

Jimmy

    Jimmy,

    I answered in your last post that was the same: I don't understand the question and what you mean by "responded to Motor control too late. Then, the motor control have noise and un-control."

    Real-time mode won't make the 28035 respond "too late". It will always take interrupts from your PWM/ADC and will not affect the performance of your processor or control loop.

    There is something else wrong with your system besides using the realtime mode.

    Are you using TI hardware and a TI SW project?

    Hi  Chris,

         Yes, I used TI HVMotorCtrl+PfcKit_v1.6 and sw project . I can look nosie and vibration easily  when  I enable Realtime Options (Halt the target before any debugger access)  to Continuous Refresh Watch window on Code Composer Studio 4 .

         When I didn't use Continuous Refresh Watch window on Code Composer Studio 4  and  I change lsw vlaue , The Motor halted and noise a little bit.

     

    Regards,

    Jimmy
