GPIO Functions

Dears,

Please Do you have an example of using these functions ?

void gpioSetOutput(uint32_t uiNumber);
void gpioClearOutput(uint32_t uiNumber);
uint32_t gpioReadInput(uint32_t uiNumber);

void gpioWriteDataBus(uint8_t uchValue);

uint8_t gpioReadDataBus(void);

Thanks in advance.

    Hi,

    What device are you using? I suppose it's one of the C66x.

    I think that there's not examples, but if you look at:

    PDK_C66xxxx_DIR/packages/ti/platform/evmc66xxl/platform_lib/src

    You will find a file called evmc66xx_gpio.c, there you will find the functions definitions. Those functions use the gpio functions defined in PDK_C66xxxx_DIR/packages/ti/csl/csl_gpioAux.h. There are examples for the functions defined in csl_gpioAux.h in the doxygen comments of the functions.

    Regards

    J

    Dear Johannes ,

    Yes you are right I'm using C6670

    Actually I used the functions defined in the csl_gpioAux.h based on the examples in the doxygen comments of the functions.

    So I want to make sure that there is no examples provided for the functions in this file evmc66xx_gpio.c Because I was searching a lot in order to find an examples.

    Thank you very much you helped me a lot .

    Sincerely,

    Maha
