Is anyone successfully receiving UART data using a UART configured
with greater than 9650 Baud? 

 
I have a Keil development board. 

 
I have interrupts enabled. 

 
I&amp;#39;m looking forward to hearing any feedback of success with a
UART.

I have units here currently working at 920800 baud.&lt;/p&gt;

&lt;p&gt;
Plenty of processors have UARTs specified to several
&lt;b&gt;M&lt;/b&gt;bps.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: uart receive data incorrect above 9600 baud</title><link>https://community.arm.com/thread/91182?ContentTypeID=1</link><pubDate>Thu, 25 Aug 2011 08:36:13 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:7440852f-efdb-4b86-a296-ae8b5d83df3a</guid><dc:creator>&amp;#178;erik malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
... to know what chip you use&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: uart receive data incorrect above 9600 baud</title><link>https://community.arm.com/thread/66858?ContentTypeID=1</link><pubDate>Thu, 25 Aug 2011 07:49:03 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:030b6fbf-9425-4c08-b673-d8f589a4ec0e</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
Yes, I have managed to receiev UART data at baudrates with several
digits more. Many processors are able to run at 115200, 230400 or
faster - potentially even one digit more faster.&lt;/p&gt;

&lt;p&gt;
But how relevant is that?&lt;/p&gt;

&lt;p&gt;
You haven&amp;#39;t managed to tell us what processor you have. Or what
development board. For some reason, you didn&amp;#39;t even find it important
to tell if you use an ARM processor, or a 8051 or something else.&lt;/p&gt;

&lt;p&gt;
By the way - max baudrate is two things.&lt;/p&gt;

&lt;p&gt;
Max correct baudrate to handle without signal integrity problems
or lost data.&lt;/p&gt;

&lt;p&gt;
Or max baudrate error to handle without too high percentage
baudrate errors (i.e. how much away from 9600 baud can a sender be
and still have low error bitrate).&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: uart receive data incorrect above 9600 baud</title><link>https://community.arm.com/thread/66859?ContentTypeID=1</link><pubDate>Thu, 25 Aug 2011 07:46:20 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:4210496e-ab11-4c55-b4cb-053700f86b52</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;

&lt;p&gt;
Yes.&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;I have a Keil development board&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Would you care to be a little less vague?&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;I have interrupts enabled&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
How interesting!&lt;/p&gt;

&lt;p&gt;
But are you &lt;i&gt;&lt;b&gt;using&lt;/b&gt;&lt;/i&gt; them properly?&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;I&amp;#39;m looking forward to hearing any feedback of success with a
UART&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
It should be fairly obvious that there&amp;#39;s a vast number of devices
in the world successfully using UARTs...&lt;/p&gt;
