Dear,
I tried the same code on :
https://devzone.nordicsemi.com/f/nordic-q-a/43774/simple-gpio-example---nrf9160-dk/173275#173275
and my code:
#include <zephyr.h>
#include <device.h>
#include <gpio.h>
/* 1000 msec = 1 sec */
#define SLEEP_TIME 5000
void main(void)
{
int cnt = 0;
struct device *dev;
dev = device_get_binding("GPIO_0");
/* Set LED pin as output */
gpio_pin_configure(dev, 2, GPIO_DIR_OUT); //p0.03 == LED2
gpio_pin_configure(dev, 3, GPIO_DIR_OUT); //p0.04 == LED3
gpio_pin_configure(dev, 4, GPIO_DIR_OUT); //p0.03 == LED2
gpio_pin_configure(dev, 5, GPIO_DIR_OUT); //p0.04 == LED3
gpio_pin_configure(dev, 17, GPIO_DIR_OUT); //p0.17
gpio_pin_configure(dev, 18, GPIO_DIR_OUT); //p0.18
gpio_pin_configure(dev, 19, GPIO_DIR_OUT); //p0.19
while (1) {
/* Set pin to HIGH/LOW every 1 second */
gpio_pin_write(dev, 2, cnt % 2); //p0.03 == LED2
gpio_pin_write(dev, 3, cnt % 2); //p0.04 == LED3
gpio_pin_write(dev, 4, cnt % 2); //p0.03 == LED2
gpio_pin_write(dev, 5, cnt % 2); //p0.04 == LED3
gpio_pin_write(dev, 17, cnt % 2); //p0.17 Toggling pin 17
gpio_pin_write(dev, 18, cnt % 2); //18
gpio_pin_write(dev, 19, cnt % 2); //19
cnt++;
k_sleep(SLEEP_TIME);
}
}
The Led1,2,3,4 will on/off in 5s, but P0.17 P0.18 P0.19 didnt change !!
Something else do we need to setup?

the define for gpio;

is it correct?
Plz tell me where is wrong on my code
Thanks
