while merging blinky + timer , found an error nrfx_config.h: No such file or directory

[ps_anu]

hi.........

 i am tried to merge the blinky and timer sample program , i am getting this error , even i have included all files .h , .c files

nrfx_config.h: No such file or directory

[rohit]

you have to link this file and enable driver into SDK_CONFIG.h file.

[ps_anu]

how  to do that 

[rohit]

which SDK are you using?

[ps_anu]

sdk 15.2 version ...

[rohit]

I am using SDK 15.2.0-PCA10040-S132

I merge Blinky code into timer code.

Its showing 0 error.

good , but what mistake in my file i used application timer 

[rohit]

I am using Keil tool. I didn't check your file?

Above code working from my side.

Please Post your code. I can't understand your problem?

ps_anu said:

application timer 

which example it is?

Please explain clearly.

[ps_anu]

look at this code 

#include <stdbool.h>
#include <stdint.h>
#include "nrf_delay.h"
#include "boards.h"
#include "nrf_delay.h"
#include "app_timer.h"
#include "nrf_drv_timer.h"



#define APP_TIMER_DE(m_led_a_timer_id);

static void timer_sensor_event_handler(nrf_timer_event_t event_type, void* p_context)
{

void bsp_board_leds_on(void)
{
    uint32_t i;
    for (i = 0; i < LEDS_NUMBER; ++i)
    {
        bsp_board_led_on(i);
    }
}
}

static void create_timers(void)
{  
   uint32_t err_code;

    // Create timers
  
 

    err_code = app_timer_create(&m_led_a_timer_id,
                                APP_TIMER_MODE_REPEATED,
                               timer_sensor_event_handler);
  APP_ERROR_CHECK(err_code);
}

static timer_start(void)
{
   uint32_t err_code;
    //uint32_t APP_TIMER_TICKS(50000);
   
       
    // Start application timers
    err_code = app_timer_start(m_led_a_timer_id, APP_TIMER_TICKS(50000), NULL);
    APP_ERROR_CHECK(err_code);
     NRF_LOG_INFO("SUCCESS1");          

}



/**@brief Function for application main entry.
 */
int main(void)
{
    // Initialize.
app_timer_init();
     create_timers();
    
    // Enter main loop.
    for (;;)
    {
        idle_state_handle();
    }
}

tell me if you can't understand this 

[rohit]

First, check my code. let me know its working or not?
