hi all, 

 
I have some starting problem for the I2C coding in LPC2103,Could
ay body help me with this.I need to configure the I2C in master
mode. 

 
I have configured the P0.2 &amp;amp; P0.3 for I2c and i have
understood the sequence for the Tx &amp;amp; Rx.my problem</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: I2C problem</title><link>https://community.arm.com/thread/135104?ContentTypeID=1</link><pubDate>Sun, 26 Aug 2007 06:21:22 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:460d179a-2ad5-4cce-93bf-ac7d8243a3f6</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
NXP likes to place watered down summary information in their data
sheets, and call the real document User Manual. It is quite
nonintuitive, with a data sheet that often doesn&amp;#39;t even mention the
power consumption of a chip...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: I2C problem</title><link>https://community.arm.com/thread/124014?ContentTypeID=1</link><pubDate>Thu, 23 Aug 2007 02:11:04 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:9cf73430-1b30-41e2-a73a-5e2c5ea46911</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Well, NXP have really messed-up their website to give stupid URLs
like that!&lt;/p&gt;

&lt;p&gt;
However, if you click &lt;a href="http://www.nxp.com/pip/LPC2101_02_03_1.html"&gt;www.nxp.com/.../LPC2101_02_03_1.html&lt;/a&gt;
you will still end up in the same place!&lt;/p&gt;

&lt;p&gt;
&lt;b&gt;:-)&lt;/b&gt;&lt;/p&gt;

Neil ,&lt;/p&gt;

&lt;p&gt;
I had gone through the websites again ,I found my answer ,in the
user mannual they specified the details of the I2C communication .
Now i started writing the code .&lt;/p&gt;

&lt;p&gt;
I was following same way of finding the Deails, which i did for
ADSP and Micochip Ic&amp;#39;s .&lt;/p&gt;

&lt;p&gt;
thanks alot for the help ,&lt;br /&gt;
&lt;i&gt;&lt;br /&gt;
Thanks,&lt;br /&gt;
Paul&lt;br /&gt;&lt;/i&gt;&lt;br /&gt;

I don&amp;#39;t know if it&amp;#39;s also true of their ARM parts, but NXP tend to
have both a Data Sheet and a &lt;b&gt;User Manual&lt;/b&gt; for their &amp;#39;51
derivatives - and you &lt;b&gt;need&lt;/b&gt; to read &lt;i&gt;&lt;b&gt;both&lt;/b&gt;&lt;/i&gt; of
them...&lt;/p&gt;

&lt;p&gt;
Are there really no application notes, and no examples?!&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: I2C problem</title><link>https://community.arm.com/thread/75393?ContentTypeID=1</link><pubDate>Tue, 21 Aug 2007 04:01:25 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:389dd8e9-a1ce-4358-b0b2-120c9b88deb5</guid><dc:creator>Shanid Paul</dc:creator><description>&lt;p&gt;&lt;p&gt;
hello,&lt;/p&gt;

&lt;p&gt;
Thanks i have checked it ,Except the register reading and writing
it is not specifying any thing more, i mean nothing about program
flow&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: I2C problem</title><link>https://community.arm.com/thread/51050?ContentTypeID=1</link><pubDate>Mon, 20 Aug 2007 05:33:49 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:532778d8-e142-48c5-a7e1-a330f6612aa5</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
I haven&amp;#39;t checked specifically for the LPC2103, but for most
chips, NXP has a zip file containing a lot of example code for all
devices. Have you visited the product page and looked for the
available info?&lt;/p&gt;
