dsp/bios and headers

hi,

i`m doing a simple program that use dsp/bios and i use the headers files ("dsp2833x_device.h" and "dsp2833x_examples.h"), when i compile the program a lot of errors and warnings apears. I read the pdf spra958h, and i want to know if there is another pdf to use or link to see to make this clear. I see the examples using dsp/bios in that pdf but there is somthing that i don`t understand

1) If i use the dsp/bios i have to include in my program the generate files (.cmd and xxcfg.h), but that examples don`t use the last one. way?

2) Don`t include the std.h, log.h etc. way?

Thanks

Gaston

    Gaston,

    What error messages are you receiving? The examples from SPRA958H correctly use DSP/BIOS in the application. Can you compile these examples without any issue?

    1) I opened the example project and both the .cmd and xxcfg.h was included. I opened the F28335 Flash BIOS example.

    2) The std.h and log.h files are included in the cfg.h file.

    Tim,

    Thanks for reply, i solve it.I read it and i see that use other Piectrl and defaultIsr (PieCrtl_bios and defaultIsr_bios), as i can see the only thing that change is the hwi_vec in the PieCtrl_bios and the trcdata in the main program. I have some question about this:

    1) If i wanto to use the ADC for example, i have to change some sources? When i have to do it?

    2) Why use the f28335_bios_ram.com? Can i define something like that in the program instead of make some link? i see other examples that use flash and see the #pragma.

    3) I see that define xxcfg.h in the example.h (the header file) and use to define some function prototypes as extern, way? Is different if i define it in the program?

    4) Can yu explain me this:

    extern Uint16 hwi_vec_loadstart;

    extern Uint16 hwi_vec_loadend;

    extern Uint16 hwi_vec_runstart;

    Sorry for some many questions.

    Thanks.

    Gaston.
