TMS320F28335: How to Convert version 12.2 code to v5.3.0. ?

AYUSH DUBEY

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE

Dear Team

I have written ccs code for close-loop PI control in version 12.2.0,but my microcontroller is compatible with version 5.3.0.

Kindly suggest how to proceed in terms of the c2000 version , DCL.h header files,compatibility of header files.

Thanks and Regards

The DCL doesn't depend on the device and the C2000Ware. You can find some examples using the DCL library in C2000 Digital Power SDK.

Hi Ayush,

As Yanming states, DCL doesn't depend on C2000Ware, it's a standalone library that can be compiled regardless of CCS and C2000Ware version.

Nonetheless, if you had any errors or warnings due to newer versions, feel free to post them here so we can address it approporately.

Best,

Sen Wang
