How can i set a timer in my project?

[ced27]

Hello everyone,

I want to be able to set a timer in my project. With this timer i want to be able to make my current comsumption evaluation easier.

I am using the nrf9160 DK.

I proceeded the following way:

#include <zephyr.h>
#include <stdio.h>
#include <nrf9160.h>
#include <device.h>

#define TIMER_INTERVAL_SEC 1

struct k_timer my_timer;

void my_expiry_function(struct k_timer *timer_id){};


void main(void){

        k_timer_init(&my_timer, my_expiry_function, NULL);
        k_timer_start(&my_timer, K_SECONDS(TIMER_INTERVAL_SEC), K_SECONDS(TIMER_INTERVAL_SEC));
        
}

unfortunately it is not working, can someone please help me resolve this issue?

Best regards,

Cedric

I tested your sample and was able to make it work

• Extract the following project to ncs

simple_timer.zip

• Build it with the board nrf9160dk_nrf9160_ns
• Open a serial terminal and you will see the following output:

26 NRF_I2S              Non-Secure	OK
27 NRF_GPIOTE1          Non-Secure	OK

SPM: NS image at 0x10000
SPM: NS MSP at 0x200159a0
SPM: NS reset vector at 0x12379
SPM: prepare to jump to Non-Secure image.
