the question is: 
i have a led text display monocrome (amber and green and) 
i know distance from each leds 
i know number of led 
i know angle and mcd of each leds 

 
i want to can calculate cd/mq of entire displays? 
can c do it? 

 
thank you

Are you going to use that display as a flashlight? The computation
you are interested in might not be as interesting as you think, since
there is a big difference between how much light you get from a
display, and how readable it is in different external light
conditions and from different distances and angles.&lt;/p&gt;

&lt;i&gt;i want formula&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Ah. The god complex, yet again.&lt;/p&gt;

Again, what would be the point of doing it on an ARM?&lt;/p&gt;

&lt;p&gt;
And what is the point of writing a custom program?&lt;/p&gt;

&lt;p&gt;
Use a &lt;b&gt;spreadsheet&lt;/b&gt;.&lt;/p&gt;

&lt;p&gt;
On a &lt;b&gt;PC&lt;/b&gt;.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: help help HELP HELP Led luminance calculator i need HELP</title><link>https://community.arm.com/thread/79319?ContentTypeID=1</link><pubDate>Thu, 26 May 2011 12:22:34 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:555d93af-287b-46dd-b660-989815dce223</guid><dc:creator>koky mandrilla</dc:creator><description>&lt;p&gt;&lt;p&gt;
yes:&lt;/p&gt;

&lt;p&gt;
i have a led text display monocrome (amber and blue)&lt;br /&gt;
i know distance from each leds&lt;br /&gt;
i know number of led&lt;br /&gt;
i know angle and mcd of each leds&lt;/p&gt;

&lt;p&gt;
i want formula&lt;/p&gt;

&lt;p&gt;
i want to calculate in c&lt;br /&gt;
or python&lt;br /&gt;
or free pascal&lt;br /&gt;
not delphi?&lt;/p&gt;

&lt;p&gt;
you have example for arm?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: help help HELP HELP Led luminance calculator i need HELP</title><link>https://community.arm.com/thread/66619?ContentTypeID=1</link><pubDate>Thu, 26 May 2011 12:01:11 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:897a9b5c-a879-4648-a0eb-5849b37a2d66</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Do you mean &amp;#39;C&amp;#39; as in the programming language?&lt;/p&gt;

&lt;p&gt;
A programming language is just a means for &lt;b&gt;you&lt;/b&gt;, the
programmer, to express &lt;b&gt;&lt;i&gt;your&lt;/i&gt;&lt;/b&gt; solution to the problem in
such a way that it can be executed by a processor.&lt;/p&gt;

&lt;p&gt;
The programming language does not actually &amp;quot;do&amp;quot; anything for
you.&lt;/p&gt;

&lt;p&gt;
But why would you want to do this in &amp;#39;C&amp;#39;? And, particularly, on an
ARM?&lt;/p&gt;

&lt;p&gt;
Surely, a PC would be a far more suitable platform - and a
&lt;b&gt;spreadsheet&lt;/b&gt; or suchlike a far more suitable tool...?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
