(LPC2148) 
in Master and slave mode??? 
is it possible ???

Sir, I just want to connect several ARMs(LPC2148) by using UART0.
here one will be master and will be slaves.master will communicate
with all of its slaves n he is the only to start communication, give
commands and end it.&lt;/p&gt;

&lt;p&gt;
master will start communication by sending &amp;quot;wake up Seed&amp;quot; on its
TXD. on receiving this all the slaves will wake up because after
&amp;quot;wake up&amp;quot; there is slave addrs(the slave master want to
communicate).&lt;/p&gt;

&lt;p&gt;
the slave which addrs is sent by master will only communicate with
master and all other will do their normal work.&lt;/p&gt;

&lt;p&gt;
after this master will send command on its TXD which will be
received only by that slave and according to master that slave will
work&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: arm 7 help</title><link>https://community.arm.com/thread/57895?ContentTypeID=1</link><pubDate>Mon, 15 Mar 2010 09:55:02 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:fe21abb5-29ee-4924-a223-a6afa9231eb2</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
What do &lt;i&gt;you&lt;/i&gt; mean by &amp;quot;Master and slave mode&amp;quot; here?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
