For it to work you will need to change the PIN_IN and PIN_OUT defines in the example to match the pins you have connected your button and led to. The defines should be changed to the port number of the pins you are using. As an example, if you want the button to be on P0.22, and the led on P0.24 you would change the defines from</p> <pre><code>#define PIN_IN BSP_BUTTON_0 #define PIN_OUT BSP_LED_0 </code></pre> <p>to</p> <pre><code>#define PIN_IN 22 #define PIN_OUT 24 </code></pre> <p>Best regards</p> <p>Jørn Frøysa</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/82073?ContentTypeID=1Sat, 01 Apr 2017 03:33:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4fddebac-a547-4917-ae28-82df511a1145Reeshma<p>yes sir, i have interfaced the buttons and leds other than those on the DK</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/82072?ContentTypeID=1Fri, 31 Mar 2017 13:14:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d9e7706a-773e-4864-9df7-3305b0a18089J&#248;rn<p>What do you mean you are externally interfaced? Are you using buttons and leds other than those on the development kit? When you tried the example code, did it work as intended?</p><div style="clear:both;"></div>
