Hi! 
I have a problem receiving (by interrupt) more than a byte from
serial port on STM32 project. could you please post an example
code? 

 
void USARTx_IRQHANDLER(void) 
{ if (USART_GetITStatus(USART3, USART_IT_RXNE)) { /* Read one byte

You mean, &lt;i&gt;&amp;quot;With &lt;b&gt;STM32&lt;/b&gt; chips, you have debugging
available...&amp;quot;&lt;/i&gt;&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: USART bytes stream rx problem on STM32f20x</title><link>https://community.arm.com/thread/61208?ContentTypeID=1</link><pubDate>Thu, 04 Oct 2012 11:09:56 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:9662613b-75ef-4e7c-b686-73f28984cae9</guid><dc:creator>F F</dc:creator><description>&lt;p&gt;&lt;p&gt;
Possible solutions (given the clarity of the stated problem):&lt;/p&gt;

&lt;p&gt;

hardware,software,registers,timing,configurization,processing,contention,error
handling,steps,sampling,noise,mode,detection,amplitude,rate,quantization,deviation,accuracy,limits,tolerances,transitions,length,parity,chronousity,clocks,protocol,etc....&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: USART bytes stream rx problem on STM32f20x</title><link>https://community.arm.com/thread/61207?ContentTypeID=1</link><pubDate>Thu, 04 Oct 2012 08:15:22 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:54522876-aa72-4dea-a05c-0c97e2037c0b</guid><dc:creator>&amp;#178;erik malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
&lt;i&gt;I have a problem&lt;/i&gt;&lt;br /&gt;
no, you have two&lt;br /&gt;
1) reading and following the instructions in the &amp;quot;Enter Message
Details Below&amp;quot;&lt;br /&gt;
2) telling WHAT the problem is. With SILabs chips, you have debugging
available to state things like e.g. &amp;quot;the ISR does not get called&amp;quot;&lt;/p&gt;

&lt;p&gt;
downloading some code or throwing it together and then posting it
is not an accepted debugging method&lt;/p&gt;

&lt;p&gt;
Erik&lt;/p&gt;
