DRV8312-69M-KIT: Programming of motor parameters

Part Number: DRV8312-69M-KIT

Hello to all,

I would like to ask how is it possible to first extract motor parameters from the C2000 motor controller and save as a setting file? 

Second, is there a way to manually program the C2000 motor controller with motor parameters when different motor types are attached?

    1. You can save the motor parameters in on-chip flash or external memory like eeprom via I2C/SPI, or transmit these parameters to PC to save as a data file.

    2. You can define different motor parameters in a header file as user.h, and then change the motor parameters variables of gUserParams as USER_setParams(&gUserParams), to call below 3 functions to re-setup motor parameters for instaSPIN.
    CTRL_setParams(ctrlHandle,&gUserParams);
    CTRL_setUserMotorParams(ctrlHandle);

    Thank you very much for your help and response! 

    1. - for the software extraction portion, is this done via motorware?

    2. - where are these being called from? GUI Composer?

    1) Writing to an external memory must be taken care of in user code, we do not provide this feature by default in our examples
    2) There are API that copy user variables/settings from the user.h into the gUserParams struct during run time in the Motorware example code. These API are mentioned in Yanming's post. You'll need to look at the example source code to see where these are called; the GUI simply acts on a compiled source project that is handed to the GUI in form of a .out file. You won't get any idea of what's happening "under the hood" by using the GUI tool
