GPIO configuration code

[Sadasivam]

Sir,

We want to know about sample code of how to configure GPIO pins as output, and let we know how to include them for led toggling.

[Roger Clark]

To configure a pin as output you just need to use (Assuming your LED is on pin 29)

#define LED_PIN 29

nrf_gpio_cfg_output(LED_PIN);// Set LED PIN pin as output

To set the pin to High , use

nrf_gpio_pin_set(LED_PIN);

to set the pin to low, use

nrf_gpio_pin_clear(LED_PIN);

to toggle the pin use

nrf_gpio_pin_toggle(LED_PIN);

Note. You need to include "nrf_gpio.h"
