CCS/TMS320F28335: tms320f28335

Expert 1120 points

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hi,

I am new to embedded , i have coded a program for ADC using tms320f28335 while developing i could find some issues like are the registers have to be initialized using "union or struct" and the header file has a desired variable for it , but when i utilize the variable i get an error such as 

Description Resource Path Location Type
#148 declaration is incompatible with "volatile struct ADC_REGS AdcRegs" (declared at line 273 of "..\DSP2833x_Adc.h") main.c /1 line 3 C/C++ Problem


can someone clarify it, and again by declaring some other variable for the struct i could execute the program my question is why the variable in the header file doesn't works?

    Hi,

    DSP2833x_Adc.h declares AdcRegs variable as follows:

    extern volatile struct ADC_REGS AdcRegs;

    The header does not have a desired variable. It contains a declaration for this variable and the definition of this variable has to be provided somewhere else.
    Your definition or declaration of AdcRegs violates the declaration from the header.

    Based on what I see here, I can't give you any specifics on how to fix the problem.  But I can give some general pointers.

    Add the build option --verbose_diagnostics.  The compiler echoes the problem source line with a mark to the point in the source line where the problem begins.  This usually makes the error easier to understand.  Look for this output in the Console view, and not the Problems view.

    Please see this FAQ (not from TI) for general background on how declarations and definitions are typically handled.

    Thanks and regards,

    You do not link required libs.
    Import an ADC example for 28335x, compare a list of libraries used by your project with a list of libs used by an example.
    Add one by one to find what is needed by your project.

    Follow Tom's advice. You are missing some source files in your project. I suggest referring to the ADC examples in C2000Ware or starting with one of those then doing your edits.

    Best regards

    Those were the errors from the adc_soc example found from the getting started page, i did include al the libraries

    Sasi,
    I imported Example_2833xAdcSoc project from C2000Ware v1.0.6.0,
    added dependency on C2000Ware v1.0.6.0 to the project
    and compiled it without any errors or warnings.

    I see no errors importing that example in C2000Ware 1.00.06.00. Where did you import it from?

    Best regards
