 With sdk13 and app_pwm library, I only got 9bits resolution for 32KHz freq. 
 The pwm should have 16bits resolution, with max freq 100KHz?
please could anyone confirm that.</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 06 Jun 2017 13:17:28 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/22567/nrf52832-pwm-limitations" /><item><title>RE: NRF52832 PWM limitations</title><link>https://devzone.nordicsemi.com/thread/88787?ContentTypeID=1</link><pubDate>Tue, 06 Jun 2017 13:17:28 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:8644ccef-4fca-4713-938c-e7d91db0258a</guid><dc:creator>ovrebekk</dc:creator><description>&lt;p&gt;Turbo is correct.

&lt;/blockquote&gt;
&lt;p&gt;Nope: Base PWM frequency is 16MHz. &lt;code&gt;16MHz/32khz = 500&lt;/code&gt;. Those 500 are just short of &lt;code&gt;9bits=512&lt;/code&gt;.&lt;/p&gt;
&lt;p&gt;More bits would require a lower PWM frequency.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
