Hi 
I want to measure a value of 100 nF 
I generate a pwm signal of 1 Khz and I intend to measure the time
ramp down till 3.6 V of capacitor 

 
Can anybody a little help? 
Thank&amp;#39;s

You know that it was fast first when you have managed to get
everything working.&lt;/p&gt;

&lt;p&gt;
Right now, you are asking for help on this forum, which indicates
that it may not have been a working short cut - you are stuck and
asking for help...&lt;/p&gt;

I fiind the code in my computer in my projects&lt;br /&gt;
I decide how I make the project and it was fast to use that code.
....&lt;/p&gt;

So you&amp;#39;re just grabbing any piece of code that you happen to find
- without considering the actual &lt;b&gt;requirements&lt;/b&gt; of your
project?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: capacitor measure value</title><link>https://community.arm.com/thread/115711?ContentTypeID=1</link><pubDate>Tue, 27 Apr 2010 02:32:15 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:4820ffdc-ac96-4808-a413-9dd2bc4cb5df</guid><dc:creator>Rotar dumitru</dc:creator><description>&lt;p&gt;&lt;p&gt;
because I fiind the code with modulated pulse&lt;br /&gt;
and I use this&lt;br /&gt;
if you have another method tell me&lt;br /&gt;
i try it ..&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: capacitor measure value</title><link>https://community.arm.com/thread/103924?ContentTypeID=1</link><pubDate>Tue, 27 Apr 2010 02:27:51 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:485ae246-b746-49f0-b5e2-694b35c76b55</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Why does the pulse width need to be modulated?&lt;/p&gt;

First method is was with ic 555 and read the pulses on digital
port&lt;br /&gt;
but this method it was not stable and big tolerance&lt;br /&gt;
I don&amp;#39;t now why....&lt;br /&gt;
I take this new method&lt;br /&gt;
I can see on the osciloscope is stable the ramp&lt;/p&gt;
