How to configure GPIOs as input or output?

[Aditya Narayan Tripathi]

Control output of a GPIO with just one LED. Control input of a GPIO with one button.

[endnode]

Have you tried BSP example from nRF5 SDK? Anything unclear there?

[Joakim Jakobsen]

One way to configure the GPIOs is to use the nrf_gpio interface directly:

1. Configure pin as output: nrf_gpio_cfg_output(pin_number)

2. Configure pin as input : nrf_gpio_cfg_input(pin_number)

3. Turn on/off the LED:

   nrf_gpio_pin_set(pin_number) nrf_gpio_pin_clear(pin_number)

Hope that helps!

Did you take a look in the infocenter about the BSP or about the Button Handler?
