I am new to ccs. Can anyone tell me how to use modules in digital motor library in my ccs project? the document does not provide clear instructions. Thanks in advance.

    Hi Sameer,

    Which controller are you using? Also, which document did you refer previously?

    Regards,
    Gautam

    I am using f28069 piccolo. I referred the dmclib.pdf.

    Is this the doc: C:\ti\controlSUITE\libs\app_libs\motor_control\math_blocks\v4.3\~Docs

    DMC MATH_v13.1.pdf has in-depth description of all the math blocks.

    Regards,

    Check this: http://www.ti.com/tool/sprc215
    It includes source code with the library. Its meant for F280x but you can refer the same for similar approach.
