https://devzone.nordicsemi.com/f/nordic-q-a/17244/reading-current-ticks-in-rtc-during-operationHello, I want to read the current ticks in RTC0, and want to measure the time elapsed after some events by using ticks to milliseconds. Basically i want to display the time in milliseconds as soon as i start the program so i am using RTC for thaten-USTelligent Community 13Mon, 24 Oct 2016 12:06:21 GMThttps://devzone.nordicsemi.com/thread/66234?ContentTypeID=1Mon, 24 Oct 2016 12:06:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:73ad69f6-743f-46d4-aa51-01bbca45d44eJ&#248;rgen Holmefjord<p>Hi,</p> <p>You can read the value of the RTC0 counter from the register <code>NRF_RTC0-&gt;COUNTER</code>. Notice that the timer will overflow, and you need to account for this in your timekeeping application. Check out <a href="https://devzone.nordicsemi.com/question/53893/best-way-to-implement-system-clock-on-nrf51/?answer=54538#post-id-54538">this post</a> about overflow counting using timer library. If you are using a softdevice, direct access to RTC0 is blocked. You can use RTC1 with the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/lib_timer.html?cp=4_0_0_3_28">Timer library</a> if you use a softdevice.</p> <p>Conversion from ticks to ms can be done like <a href="https://devzone.nordicsemi.com/question/39307/ticks-to-ms-calculation/?answer=39340#post-id-39340">this</a>.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
