https://devzone.nordicsemi.com/f/nordic-q-a/47516/delay-generation-using-timer-interruptHi All, Currently in my project i&#39;m using hard core delay and delay is custom i.e some places i have used millisecond and in some places used microsecond and in sec.But i wanted to generate delay using timer interrupt.Can anyone tell me how to generateen-USTelligent Community 13Tue, 21 May 2019 06:24:42 GMThttps://devzone.nordicsemi.com/thread/188083?ContentTypeID=1Tue, 21 May 2019 06:24:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:33083d79-b009-490b-bb7f-52583cbd725fAmanda Hsieh<p>Hi,&nbsp;</p> <p></p> <p>I am not sure that I understand your question.</p> <p>You will either have to use nrf_delay.h&nbsp;by using nrf_delay_us(), which will work as long as you don&#39;t need exact timing and the code is not interrupted (in which case it will be that that much longer).</p> <p>You can use an RTC for this, but one is taken by the softdevice and the other by the app_timer module, so that might not work for you.</p> <p>Then the last option is to use a TIMER, for instance look a the \examples\peripheral\timer\ in the SDK, then you can use the nrf_drv_timer_us_to_ticks() to set the time until expire.</p> <p></p> <p>Best regards,</p> <p>Amanda</p><div style="clear:both;"></div>
