52810 How to set PWM output currenthttps://devzone.nordicsemi.com/f/nordic-q-a/98789/52810-how-to-set-pwm-output-currentHello, I was using app_pwm to drive the buzzer and found that the output current was very high, reaching more than 160 ma. Here are my pwm parameter Settings: APP_PWM_DEFAULT_CONFIG_1CH(250, BUZZER_PIN); // 250 --4KHZ BUZZER_PIN -- 28 app_pwm_channel_duty_seten-USTelligent Community 13Mon, 17 Apr 2023 08:36:45 GMTRE: 52810 How to set PWM output currenthttps://devzone.nordicsemi.com/thread/420690?ContentTypeID=1Mon, 17 Apr 2023 08:36:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8b7e9668-4b5b-4bd3-90b1-4c04645bde90Simonr<p>Glad to hear that! 6mA sounds much more reasonable than 160 indeed!</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>RE: 52810 How to set PWM output currenthttps://devzone.nordicsemi.com/thread/420689?ContentTypeID=1Mon, 17 Apr 2023 08:27:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df68d0cc-7923-4b4f-9927-3114711f38feZhang|<p><span class="tgt color_text_0" data-section="0" data-sentence="0" data-group="0-0">I think I found the problem. It seems to be due to the hardware circuit. I used the audion to amplify the square wave signal.</span><span class="tgt color_text_0" data-section="0" data-sentence="1" data-group="0-1"> This may be the cause of the excessive current.</span><span class="tgt color_text_0" data-section="0" data-sentence="2" data-group="0-2"> Because when I use pwm to drive the led, the current is only about 6ma.</span></p><div style="clear:both;"></div>
