Are you not able to program ryou board at all now? In that case can you please have a look at these links to see if they can help you out? 1 2 3

Have you tried debugging yet and stepped through the code to see where it stops?

i have included only the button part of my program and then i downloaded into the KIT but am not getting any response from the kit, the kit respond only for blink example and foor other it remains stagnant, i erase the kit completely after that also nothign happens so i cant able to analyze your suggesstion

If wonder if it could be a faulty high frequency crystal. The blinky example is using the internal 16MHz RC oscillator, but the PWM is using the external crystal. Are you able to start the crystal and check if it is running correctly? You can do it like this just use HFCLK instead of LFCLK.

Or you can remove the line:

NRF_CLOCK->TASKS_HFCLKSTART = 1;

at the expense of some frequency accuracy.

i did like what you have said but after downloading the code to DK nothing happens just asusal only for blink example it is working and for the rest of the other program it is not working how can i solve this issue?

If USE_WITH_SOFTDEVICE is set to 1 it means that you plan to use the PWM and Bluetooth concurrently. From your code it looks like you are not using a softdevice so USE_WITH_SOFTDEVICE should be set to 0. Let me know how it goes after your debugging.

USE_WITH_SOFTDEVICE defined as 1 and can you please tell me what is the difference between softdevice 1 and 0? and moreover i didnot debugges the program yet i will do that

Have you changed the example at all?

Is USE_WITH_SOFTDEVICE defined as '1' or '0'?

Have you debugged the code to see where the example stops?

no i have tested the Basic LED blink program it is working fine but if i flash this program am not getting any response and also i have erase the developement kit after that also nothing happen

So since the LED does not toggle it means that your application is stuck somewhere. Are you able to run the basic LED blinky example from one of the SDKs? Are you using a custom board or a dev kit? Could it be that your external 16MHz crystal is not working properly?

Hi, am using BUZZER ELEMENT STD 9KHZ this buzzer and i ahve conencted to pin 14 of nrf51DK , concerning my program its just got compiled but am not getting the LED toggling and am still looking for that issue

Hi. What kind of buzzer do you use? Are you able to confirm that your example is running properly on your board and outputting the correct signal? Is the LED toggling?
