How to make application run with softdevice

Question

I made Pwm program with 3 channels without using softdevice and without using interrupts at that time it is working perfectly. But when i am trying to use softdevice with ppi as sd_ppi_xxxx my program is not working. I refered softdevice specification it says that to start using softdevice,the application initializes it with aclock source and pointer to an error handler. but i dont know what does it mean.can any one please explain with some examples.

my program is :

/*

PWM channel program with softdevice ON */

#include <stdbool.h> #include <stdint.h> #include "nrf.h" #include "nrf_gpiote.h" #include "nrf_gpio.h" #include "s110/nrf_sdm.h"

#define PWM_1 (21) #define PWM_2 (22) #define PWM_3 (23)

#define TIMER_PRESCALERS 6U /**< Prescaler setting for timer. */

/*Function for handling timer 2 peripheral interrupts. / / Function for initializing the Timer 2 peripheral. */ static void timer2_init(void) { // Start 16 MHz crystal oscillator . NRF_CLOCK->EVENTS_HFCLKSTARTED = 0; NRF_CLOCK->TASKS_HFCLKSTART = 1;

// Wait for the external oscillator to start up.
while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0);

NRF_TIMER2->MODE        = TIMER_MODE_MODE_Timer;
NRF_TIMER2->BITMODE     = TIMER_BITMODE_BITMODE_08Bit << TIMER_BITMODE_BITMODE_Pos;
NRF_TIMER2->PRESCALER   = TIMER_PRESCALERS;

// Clears the timer, sets it to 0.
NRF_TIMER2->TASKS_CLEAR = 1;

// Load the initial values to TIMER2 CC registers.
NRF_TIMER2->CC[0] = 0;
NRF_TIMER2->CC[1] = 255;
NRF_TIMER2->CC[2] = 1;
NRF_TIMER2->CC[3] = 1;

}

nrf_gpio_cfg_output(PWM_1);
nrf_gpiote_task_config(0, PWM_1, \
                       NRF_GPIOTE_POLARITY_TOGGLE, NRF_GPIOTE_INITIAL_VALUE_LOW);

                      NRF_GPIOTE_POLARITY_TOGGLE, NRF_GPIOTE_INITIAL_VALUE_LOW);
