Hello 
I have worked on LPC3250 on Phytec 1305.3 board. I have a question
about HSUARTs: 
Is there any difference between HSUART and UART regarding electrical
interface? 
Is it possible to communicate a standard serial port with a high
speed UART by</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: High-Speed UART vs Standart UART</title><link>https://community.arm.com/thread/65599?ContentTypeID=1</link><pubDate>Fri, 07 May 2010 05:38:58 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:c410cc6a-21f2-40af-8314-6b851bc49869</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
The respective &lt;b&gt;Datasheets&lt;/b&gt; will tell you that!&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;Is it possible to communicate a standard serial port with a
high speed UART by adjusting serial port parameters?&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
By &amp;quot;standard serial port&amp;quot;, I assume you mean the COM port(s) on a
PC?&lt;br /&gt;
Again, you will have to look at the &lt;b&gt;specifications&lt;/b&gt; for your
COM port(s) to determine what speeds they support.&lt;/p&gt;

&lt;p&gt;
I have some USB-to-Serial adaptors which support up to 921600 baud
- I call that quite &amp;quot;high&amp;quot;.&lt;/p&gt;

&lt;p&gt;
Note that a PC COM port must not be connected direct to any UART;
you must use a suitable &amp;quot;RS232&amp;quot; transceiver - which must, of course,
be specified for the maximum speed required...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
