Hey guys, I can&amp;#39;t seem to get I2C working with LPC2148. The
problem arise when I transfer data. Slave device (I2C debugger in
Proteus) doesn&amp;#39;t respond. Neither ACK nor NACK. It just get paused.
Although when I Write Slave address, Ack is given by Slave</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: I2C problem with LPC2148</title><link>https://community.arm.com/thread/83621?ContentTypeID=1</link><pubDate>Thu, 11 May 2017 03:03:04 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:4304e643-d70a-4b91-8529-e650fd9ac5ad</guid><dc:creator>arun singh</dc:creator><description>&lt;p&gt;&lt;p&gt;
Actually I don&amp;#39;t have a real I2C. That&amp;#39;s why I am using I2C
debugger in simulator.&lt;br /&gt;
I&amp;#39;ll try using my PIC microcontroller as slave and revert back.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: I2C problem with LPC2148</title><link>https://community.arm.com/thread/70023?ContentTypeID=1</link><pubDate>Thu, 11 May 2017 02:11:53 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ab4280cb-7695-4ac4-bca4-4bb2da84d9db</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Does a &lt;b&gt;real&lt;/b&gt; I2C device respond?&lt;/p&gt;

&lt;p&gt;
The LPC2148 is an NXP device; NXP own &amp;amp; invented I2C - surely
they must have working examples?&lt;/p&gt;
