GPIO configuration in ADuCM350

Hi,

I am currently working on the "ImpedanceMeasurement_4WireBioIsolated" example for ADuCM350, but for my application I need to add some input and output digital pin.

Where can I find a code example where some GPIOs are configured and used? (Input/Output, Pull-up/down resistor, set/clear bit)

Thanks for your help

Best Regards

Ivan

    Hi,

    There is a set of example codes when you install the ADuCM350 installer. In the examples folder you'll see the "GpioTest" where you will find several basic commands. I copied several lines below from the example.


    /* configure the pin as an output */
    if ((Result = adi_GPIO_SetOutputEnable(pGPIOEntry->Port, pGPIOEntry->PinValue, true)) != ADI_GPIO_SUCCESS) {
    break;
    }


    /* configure the pin as an input also */
    if ((Result = adi_GPIO_SetInputEnable(pGPIOEntry->Port, pGPIOEntry->PinValue, true)) != ADI_GPIO_SUCCESS) {
    break;
    }


    /* drive the pin high */
    if ((Result = adi_GPIO_SetHigh(pGPIOEntry->Port, pGPIOEntry->PinValue)) != ADI_GPIO_SUCCESS) {
    break;
    }

    /* drive the pin low */
    if ((Result = adi_GPIO_SetLow(pGPIOEntry->Port, pGPIOEntry->PinValue)) != ADI_GPIO_SUCCESS) {
    break;
    }
