CSL gpio problem

Hi

I'm using CCS 5.5 on 5510 DSK, and was working on controlling GPIO pins, but I have a problem that is every time i use a function from the CSL GPIO library, it returns an error, that this function is not defined, this happens also when creating a handle or configuration structure. but when i use the GPIO macros, everything works fine.

note:i already included the csl_gpio.h

any one has some solution?

regards

Aziz

    Aziz,

    Can you send a sample of the code?

    Things to check:
    -is the path of the header file included in the compiler options under "Include options"
    -is the library included in the linker options under "file search path"
    -is the path to the library included in the linker options under "file search path"

    Regards,
    John

    hi john
    thank you for your reply
    the header is included as i mentioned, and CCS is not having problem recognizing it, i can assess it from my code and i can see it also from the project tab under included files in CSL... also i added the path of the CSL folder to the search for the linker, and included the CSL library as well, those are some of the first step i do whenever i create a new project. (i don't think i have to add each library separately to the linker, do i? i usually add only the CSL lib)
    but still, i cant use the functions...
    by the way, i am including and using other libraries of CSL (DMA,McBSP...) with no problems, and also i am using the GPIO macros (GPIO_RGET(IODATA), and GPIO_RSET(IODIR,0x00) for example) and they are working fine!
    what do you think?
    best regards

    Aziz,

    Which functions are giving you trouble? I have asked some CSL experts to reply but until then I could try to reproduce on my machine and attempt to figure out what you need to include to get this working.
