https://devzone.nordicsemi.com/f/nordic-q-a/74842/pwm-configuration-to-stop-it-after-x-number-of-pulsesWe need to work with the PWM, the idea is to set one frequency, duty 50%, and put out these pulses to one pin, we understand how to do that but we need to stop these pulses after a number x of pulses, one option we think connects it with the event toen-USTelligent Community 13Tue, 11 May 2021 09:50:22 GMThttps://devzone.nordicsemi.com/thread/309172?ContentTypeID=1Tue, 11 May 2021 09:50:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:521bab21-7264-4f2b-91b4-a2c150edb003Simon<p>One option is to run the PWM from a function from main, a separate thread, or a&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.1/zephyr/reference/kernel/threads/workqueue.html">work queue</a>&nbsp;thread like this:</p> <p><pre class="ui-code" data-mode="text">static void run_pwm(struct k_work *work){ pwm_pin_set_usec(pwm, PIN, PERIOD, PULSE , 0); k_sleep(DURATION); //STOP PWM }</pre></p> <p>You could also use the NRFX api and the function <a href="https://github.com/nrfconnect/sdk-hal_nordic/blob/v1.5.1/nrfx/drivers/include/nrfx_pwm.h#L227-L259">nrfx_pwm_simple_playback()</a>.
