CCS/TMS320C28343: Global variable and pointer

Part Number: TMS320C28343

Tool/software: Code Composer Studio

Hi TI,

How to avoid the use of global variables pointer when coding?

And how to realize structrual and modularized software design?

Can you send me some docs or demo for learning?

Best regard

I'm not sure what you mean. The article Data blocking in the C2000 MCU compiler explained talks about how the compiler avoids loads of the DP register, which is used to access global variables.

That's a very general programming topic. Unfortunately, TI has no documents on it.

Thanks and regards,

There is nothing wrong with global variables in a relatively small scale system like an MCU.
