Gpio DSP/Bios API Manual or Reference not found

Other Parts Discussed in Thread: OMAPL138

Hi,

I want to use the Gpio API from DSP/BIOS. I've found some examples. But when changing them, they are not doing, what I want.
So I want to check, what is wrong.

But I'm not able to find the API Manual for the GPIO functions like Gpio_open(),Gpio_setPinDir()...

In which document is a description?

Thanks

Richard

  • Richard,

    What version of BIOS are you using?

    For which device?

    Are you using the PSP driver software?  Or CSL?

  • Hi Dave,

    I'm working with DSP/BIOS 5.41.02.14.

    I have started with this example:

    C:\C6748_dsp_1_00_00_11\pspdrivers_01_30_01\packages\ti\pspiom\examples\evmOMAPL138\gpio\build\ccs3

    The hardware is a LogicPD Experimenter Kit with OMAP L138 SOM

  • Rich,

    I'll ask someone from the PSP team to answer your question.

  • Hi Rich,

    If you want to use the GPIO API’s in your application, and to know the description of API’s provided by the GPIO driver you can refer the document(BIOSPSP_GPIO_Driver_Design.pdf) placed in: pspdrivers_01_30_01\packages\ti\pspiom\gpio\docs

    Section 1.6.1 – Gives a small description of the API’s provided by the GPIO driver.

    Section 2.1.2 – Data structures

    Section 2.2 - Gives the Flow chart of all the API’s provide by GPIO driver wherein you can clearly analyze and understand the API’s.

     

    For more details, you can also refer document(OMAPL138_BIOSPSP_Userguide.pdf) placed in: pspdrivers_01_30_01\docs\OMAPL138

    Section 4 – For details about API usage in the sample application.

     

     

    Thanks & regards,
