RE: Gpio driver current sink capability setup

Hi,

You can configure the GPIO and set the the drive level using the function nrf_gpio_cfg()

For high drive for both sinking and sourcing, use NRF_GPIO_PIN_H0H1

Snippet:

        nrf_gpio_cfg(PIN_NUMBER,
                 NRF_GPIO_PIN_DIR_OUTPUT,
                 NRF_GPIO_PIN_INPUT_DISCONNECT,
                 NRF_GPIO_PIN_NOPULL,
                 NRF_GPIO_PIN_H0H1,
                 NRF_GPIO_PIN_NOSENSE);

                 nrf_gpio_pin_write(PIN_NUMBER,0); // Set low
                 nrf_gpio_pin_write(PIN_NUMBER,1); // Set high
