Can InstaSPIN GUI log data?

Other Parts Discussed in Thread: MOTORWARE

I would like to record the current draw and EMF over a period of time while applying a known load. Can the InstaSPIN GUI or software log this data for me?

Thank you,

Matt

    To datalog you need to use the datalog functions

    C:\ti\motorware\motorware_1_01_00_07\sw\modules\dlog\src\32b

    or really just set aside some RAM and keep track of writing to the locations, and then pull them out later.

    You would need to add this code to the MotorWare project you are working on.

    as a code snippet we do somethign like this

    in defines:

    int16_t DlogCh1 = 0;
    DLOG_4CH dlog = DLOG_4CH_DEFAULTS;
    int16_t *dlogptr1;
    int16_t DLOG_4CH_buff1[ANGLE_BUFFER_SIZE];
    int16_t gGraphPrescaler = 1;

       dlog.iptr1 = &DlogCh1;
       dlog.trig_value = 0x5;
       dlog.size = ANGLE_BUFFER_SIZE;
       dlog.prescalar = gGraphPrescaler;
       dlog.init(&dlog);

    in main code:

     Gui.gRotorFluxAngle = EST_getAngle_pu(obj->estHandle);
      DlogCh1 = (int16_t)_IQtoIQ15(Gui.gRotorFluxAngle);
      dlog.update(&dlog);

     

    We have it on the to do list to add this example into MotorWare
