How Can I Create Own timers_init

[rraa]

Hi folks,

I try change blinky code for nRF52810 SoC. I must create own timer. I dont know app_timer example help for me?! I want to do when power on leds on 2 seconds. I dont want to use nrf_delay_ms(). My codes are under the topic. 

thanks...

....
standart blinky code block
....
void lfclk_request()
{
    uint32_t err_code = nrf_drv_clock_init();
    APP_ERROR_CHECK(err_code);
    nrf_drv_clock_lfclk_request(NULL);   
}
void timer_a_handler(void * p_context)
{
    nrf_drv_gpiote_out_set(Kontrol_1);
}
void create_timers()
{   
    uint32_t err_code;
    // Create timers
    err_code = app_timer_create(&m_led_a_timer_id,
                                APP_TIMER_MODE_REPEATED,
                                timer_a_handler);
    APP_ERROR_CHECK(err_code);
}
void start_timer()
{
    uint32_t err_code;

    // Start timer
    err_code = app_timer_start(m_led_a_timer_id,
                                APP_TIMER_TICKS(1000),
                                NULL);
    APP_ERROR_CHECK(err_code);
}
 
/**@brief Function for application main entry.
 */
int main(void)
{
    // Initialize.
    log_init();
    leds_init();
    timers_init();
    buttons_init();
    power_management_init();
    lfclk_request();  --->
    APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
    create_timers();  ---> 
    start_timer();    --->
    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();
    sistem_baslangici();
    // Start execution.
    NRF_LOG_INFO("Blinky example started.");
    advertising_start();

    // Enter main loop.
    for (;;)
    {
        
         sutun();
       // idle_state_handle();
    }
}

sistem_baslangici()

....
some #define and header files
....
void sistem_baslangici(void)
{
    nrf_gpio_pin_clear(Kontrol_1);
    nrf_gpio_pin_set(Kontrol_2);
    nrf_gpio_pin_clear(Motor_GERI);
    nrf_delay_ms(2000);
    nrf_gpio_pin_set(Kontrol_1);
    nrf_gpio_pin_clear(Kontrol_2);
    nrf_gpio_pin_clear(Motor_GERI);
    nrf_delay_ms(2000);
}

I solved problem like this.
