Hi,

There is a blinky example in the SDK. Its located in the folder:

<SDK_InstallFolder>\examples\peripheral\blinky

You can download the SDK 12.2 here.

i have been able to blink led with the following code, but how to use this code to generate a PWM on any other GPIO pins than the 4 LED pins given. which command to be used for setting a pin low or high?

include <stdbool.h>

include <stdint.h>

include "nrf_delay.h"

include "bsp.h" /for gpio and led declrtn/

include "nrf.h"

include "system_nrf52.h"

define ENABLE_SWD 1

static const uint8_t leds_list[LEDS_NUMBER] = { 9, 7, LED_1, LED_4 };

int main(void) { /* Configure LED-pins as outputs. */ LEDS_CONFIGURE(LEDS_MASK); int i=0;

while(true) { while(i<500)

{

                         // Start LED here

nrf_gpio_pin_clear(LED_3);

nrf_delay_ms(1000);

nrf_gpio_pin_set(LED_3);

nrf_delay_ms(1000);

                        i++;

                    }

} }
