CCS/DRV8302-HC-C2-KIT: LoadJSfile Error

user5202859

Part Number: DRV8302-HC-C2-KIT

Tool/software: Code Composer Studio

Hello,

I am using this kit with PM_Sensorless program but when I try to load the java script in the scripting console an error message appears:

"missing ; before statement [my js location] ".

I tried to find an answer in the documentation but I did not find it.

I am using ccs 9 whereas the documentation deals with ccs4 but I can't install this version.

Does someone have a solution to my problem ?

Thank you.

    You might ignore this to add the related variables to the watch window directly for debugging. The .js is just used for adding watch window variables.

    Or refer to the below code to change the .js file.

    //AddWatchWindowVars_F2803x.js

    //Add watch window variables
    expRemoveAll();
    expAdd ("EnableFlag", getDecimal());
    expAdd ("DRV_RESET", getDecimal());
    expAdd ("IsrTicker", getDecimal());

    expAdd ("SpeedRef", getQValue(24));
    expAdd ("VdTesting", getQValue(24));
    expAdd ("VqTesting", getQValue(24));

    expAdd ("cal_offset_A", getQValue(15));
    expAdd ("cal_offset_B", getQValue(15));

    expAdd ("IdRef", getQValue(24));
    expAdd ("IqRef", getQValue(24));

    expAdd ("lsw", getDecimal());
    expAdd ("dlog.prescalar", getDecimal());

    expAdd ("pid1_id.term.Ref", getQValue(24));
    expAdd ("pid1_iq.term.Ref", getQValue(24));
    expAdd ("pid1_id.term.Fbk", getQValue(24));
    expAdd ("pid1_iq.term.Fbk", getQValue(24));
    expAdd ("speed3.EstimatedSpeed", getQValue(24));
    expAdd ("pid1_spd.param.Kp", getQValue(24));
    expAdd ("pid1_spd.param.Ki", getQValue(24));

    Hello,

    Thank you for your answer. 

    It means that I need to write the variables from the Sensorless FOC of PMSM into the watch window? 

    I replaced the program in the java script by yours but it did not work. 

    Best regards.

    Could you please tell what's the operation step you did?

    You may try the step using "View->Scripting Console", copy the content in the file of the .js to the window of "Scripting Console", and then click "enter".

    If still not work, you have to add the related variables by manual. Unfortunately, I can't repeat the issue you mentioned.
