CCS/TMS320F28335: How would I find where functions are in the CCS libraries. [update_compare1]

Aquins,

I think you are attempting to build an example code and getting an unresolved symbol error for a number of functions. There is no way for CCS to know what library the functions are part of. If the functions are part of a TI library if you post the names of the unresolved symbols here we may be able to identify the library that they are part of.

Ok based on your other thread I am assuming the function you are looking for is called update_compare1(). I can going to loop in the C2000 team to assist.

Which application note are you referring to? I am unable to glean that information from your first post.

If you are new to C2000 or CCS, please review the workshops at processors.wiki.ti.com/.../C2000_Archived_Workshops. Many questions can be answered by reviewing the workshop material for your specific device family or its closest equivalent. Excellent introductory videos about CCS are available at www.youtube.com/.../CodeComposerStudio

Thank you for the replay, I know some of these should be user defined, but these are the undefined variables.

Hi,

I am referring to "Using the ePWM Module for 0% - 100% Duty Cycle Control, Literature Number: SPRAAI1", thank you for the reference materials.

Aquins,
Where did you get this code?

I would recommend that you start from a C2000Ware example. They will be correctly linked and have all identifiers defined.

Maybe the following would be a good starting point.
C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2833x\examples\epwm_updown_aq
