Part Number: MSPM0L1306

Tool/software:

In the M0L CCS development, i want to check the data type of uint16_t.

But right click- open declaration shows that could not find symbol 'uint16_t' in index

Where can I find the declaration of uint16_t?

Ok, thanks. But why cannot directly link to the declaration ?

Due to even you help provide this _stdint.h, i need to find the definition of __uint8_t

typedef __uint8_t uint8_t;

I need to check with other colleagues.

Such functionality is dependent on the indexer:

https://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_project-management.html#indexer

The indexer uses information in the project to find source/header files to index. It does not account for paths that compiler will automatically look in. One such example is the compiler include folder which has RTS header files like stdlib.h

It is likely your project does not explicitly have this include path in the project properties. I checked the MSPM0 SDK examples and they do not seem to have this either. Hence the indexer doesn't index in that location.

If you add "${CG_TOOL_ROOT}/include/c" to the list of include search paths, the indexer will then search in there and can find stdlib.h.

Thanks

Sorry, I see you are referring to other definitions like __unit8_t. The issue is likely related to my post above. Make sure the indexer is aware of the location where the relevant header files are located.
