https://devzone.nordicsemi.com/f/nordic-q-a/12258/using-timer-2-in-gpiote-sample-on-nrf-sdk-11I was playing around with the gpiote example under exaples/peripheral/gpiote. The example uses a timer, ppi, and gpiote to blink an led. By default, the app uses Timer 0 and that works well. If i were to change switch to Timer 1 or Timer 2 it doesn&#39;ten-USTelligent Community 13Wed, 02 Mar 2016 13:24:56 GMThttps://devzone.nordicsemi.com/thread/46362?ContentTypeID=1Wed, 02 Mar 2016 13:24:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8b6cfea2-7de1-4443-927f-2b109a6bc5c9Ron<p>Great thanks. I did try changing that count to adjust for 16 bits but I didn&#39;t think to change the frequency.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/46361?ContentTypeID=1Wed, 02 Mar 2016 08:40:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d6a096d8-21be-420d-be4d-a156a0b93a54Susheel Nuguru<p>The value given in led_blinking_setup:nrf_drv_timer_extended_compare -&gt;200 *1000 = 30D40 does not fit into 16-bit timer1 and timer2.</p> <p>Change the values in nrf_drv_config.h to</p> <pre><code>#define TIMER1_CONFIG_FREQUENCY NRF_TIMER_FREQ_125kHz #define TIMER2_CONFIG_FREQUENCY NRF_TIMER_FREQ_125kHz </code></pre> <p>and instead of writing 200 *1000 in led_blinking_setup:nrf_drv_timer_extended_compare you need to write 125000/2 = 0Xf424. So your LED will blink every half second.</p><div style="clear:both;"></div>
