https://devzone.nordicsemi.com/f/nordic-q-a/20515/measuring-code-execution-timehi, I would like to do some code profiling and measure execution time. What is a lowest possible resolution for the counter is possible to achieve and how? I am currently using RTC counter nrf_drv_rtc_counter_get() but have read that is not nesseceryen-USTelligent Community 13Thu, 16 Mar 2017 16:10:50 GMThttps://devzone.nordicsemi.com/thread/79983?ContentTypeID=1Thu, 16 Mar 2017 16:10:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e37b6f9c-2844-4512-ab52-36fedf2ca29dLarry<p>I see, to the highest resolution I can get is 30.517 μs using the RTC and the best option for more precise measurements is a logical analyzer.</p> <p>I would need to connect LA to GPIO and measure between toggle on/off.</p> <p>Sounds great Kristin!</p> <p>Tack så mycket!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/79984?ContentTypeID=1Thu, 16 Mar 2017 10:38:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:abbb4424-d2b7-40f9-b846-0bb7244a7c45FormerMember<p>The resolution of the RTC depends on the prescaler, see <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Frtc.html&amp;cp=2_2_0_24&amp;anchor=concept_rvn_vkj_sr">this</a> section in the Product Specification (PS).</p> <p>A TIMER using the HFCLK will have higher resolution, see <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Ftimer.html&amp;cp=2_2_0_23&amp;anchor=concept_xbd_hqp_sr">this</a> section in the PS.</p> <p>Another option is to toggle a GPIO right before and right after the code where you want to measure the execution time, and then measure the execution time using a logic analyzer.</p><div style="clear:both;"></div>
