Other Parts Discussed in Thread: CONTROLSUITE

I'm using CCSv5 and F28335

I defined a golbal const like this:

const Uint16 test = 233;

And then I writed this in main():

Voltage1 = test;

I debuged the program with XDS100, but the Voltage1 got a wrong value.

What can I do to define a golbal const?

This is not a compiler issue, but some kind of system configuration issue. I'll move this thread to the C2000 forum.

Thanks and regards,

Chen,

can you try this on a simple controlSuite example and check? if it works with the factory examples, then compare check your project properties for RTS library inclusions and proper init calls before going to main().

please let us know if usage of global constants doesn't work with factory example projects as well.

Best Regards

Thanks for reply.

I tried your advice and found it works well.

I reviewed my project and found the .cinit and .econst was moved to SARAM.

Does it have any problem?

yes, you will need them both for having a working global constants. Please refer to the compiler/linker documentation for more details on these sections.
