https://devzone.nordicsemi.com/f/nordic-q-a/52634/is-there-any-hardware-bug-with-nrf51822-s-timer2-and-rtc1Hello there, I am working in my master degree project with nordic NRF51822 microcontroller, but I faced two problems. I don&#39;t know if is a SD problem or hardware problem. Fist, the TIMER2: cannot set the prescaler with different value from 9 anden-USTelligent Community 13Fri, 27 Sep 2019 13:17:00 GMThttps://devzone.nordicsemi.com/thread/212299?ContentTypeID=1Fri, 27 Sep 2019 13:17:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4f772274-3605-426a-8840-3bdae557417bEdvin<p>Hello,</p> <p>Have you tested the TIMER and the RTC examples from the SDK? I suspect that the reason it is not working is that these are being used by something else. Do you e.g. use the app_timer module?</p> <p></p> <p>What SDK version are you using?</p> <p></p> <p>How does the TIMER2 behave different when you use prescaler = 9 and != 9?</p><div style="clear:both;"></div>
