how to modulate current in pwm square waves as per the requirementhttps://devzone.nordicsemi.com/f/nordic-q-a/30280/how-to-modulate-current-in-pwm-square-waves-as-per-the-requirementHi,..My device generated PWM square waves. I can program the frequencies and delays that is desired. but how to modulate current as per our requirement. I need the current range of 50 - 500 uAen-USTelligent Community 13Mon, 12 Feb 2018 14:29:28 GMTRE: how to modulate current in pwm square waves as per the requirementhttps://devzone.nordicsemi.com/thread/120587?ContentTypeID=1Mon, 12 Feb 2018 14:29:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2be72286-8cec-4974-84ad-deb4f17aa170Rune Holmgren<p>PWM will allow you to modulate the voltage and this is typically what you are trying to control. The current is determined by the resistance and the voltage, so (simplified a bit) if you know the resistance you can use Ohm&#39;s law to&nbsp;calculate the necessary voltage.</p> <p>Best regards,<br />Rune Holmgren</p><div style="clear:both;"></div>
