https://devzone.nordicsemi.com/f/nordic-q-a/72919/how-to-measure-cpu-load-on-nrf52840How does one measure CPU load in a 52840 application where softdevice is used? I would imagine this is a pretty standard thing that people would want to do and I would be very surprised if there is no module already available from Nordic that supportsen-USTelligent Community 13Wed, 17 Mar 2021 16:07:01 GMThttps://devzone.nordicsemi.com/thread/300496?ContentTypeID=1Wed, 17 Mar 2021 16:07:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2064e9cd-3428-4774-b239-e5f608593688Dmitry<p>Hi,</p> <p>the power control peripheral has two events that may be useful - SLEEPENTER and SLEEPEXIT. You can feed them to START and STOP tasks of a hardware timer.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/300490?ContentTypeID=1Wed, 17 Mar 2021 15:47:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f4277e01-861c-4f1f-bc00-ea6127d87128OwainIncus<p>It looks as if this is related to</p> <p><a href="https://devzone.nordicsemi.com/f/nordic-q-a/67569/pwr-mgmt-debug-pin">https://devzone.nordicsemi.com/f/nordic-q-a/67569/pwr-mgmt-debug-pin</a></p> <p>So a pin can be driven when CPU goes in and out of sleep. Wouldn&#39;t it be great if this could actually start/stop timers in HW without CPU intervention to let us calculate CPU load?</p><div style="clear:both;"></div>
