&lt;br /&gt;
That does phase-angle control; the OP still seems to be confused as to whether he actually wants phase-angle control, or pulse-width modulation (PWM)...&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to make a phase controlled triac lamp dimmer</title><link>https://community.arm.com/thread/45671?ContentTypeID=1</link><pubDate>Thu, 09 Mar 2006 04:06:07 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:345118c0-60a0-47d2-85b4-67fd747a8785</guid><dc:creator>Carsten Groen</dc:creator><description>&lt;p&gt;There is some code on my website:&lt;br /&gt;

OK, then, how do you propose to turn the TRIAC off?&lt;br /&gt;

&lt;br /&gt;
Why do you want a pulse-&lt;i&gt;width&lt;/i&gt; modulated signal if your project is &lt;b&gt;phase control&lt;/b&gt;?&lt;br /&gt;
&lt;br /&gt;
Surely you need to control the pulse &lt;i&gt;&lt;b&gt;position&lt;/b&gt;&lt;/i&gt;?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to make a phase controlled triac lamp dimmer</title><link>https://community.arm.com/thread/45664?ContentTypeID=1</link><pubDate>Tue, 07 Mar 2006 14:33:53 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:8db27a43-5901-4d53-95ca-d28255df9bb3</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;i&gt;I am new at using 8051 microcontroller .... If you know please send me the codes&lt;/i&gt;&lt;br /&gt;
&lt;br /&gt;
and after copying those you will have learned &lt;b&gt;nothing&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
before you do anything else read &amp;quot;the bible&amp;quot; and go through the Keil getting started guide&lt;br /&gt;
