Hello 

 
does anyone tried to uart an interrupt-driven uart in the
framework of Cypress? 
I mean : 
- do I need to modify putchar() to use printf()? 
- what the uart ISR need to do when TI!=0 

 
I want to use UART0 in interrupt mode, mainly for receiving</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Interrupt driven uart / printf / FX2</title><link>https://community.arm.com/thread/74961?ContentTypeID=1</link><pubDate>Mon, 26 Mar 2007 10:16:20 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:353c16a4-53a9-4460-91bb-45cb7b0fe689</guid><dc:creator>Emmanuel TILLOL</dc:creator><description>&lt;p&gt;&lt;p&gt;
I already downloaded INTSIO example.&lt;/p&gt;

&lt;p&gt;
I try to use a particular framework with the FX2 microcontroller
(cf. Cypress documentation).&lt;/p&gt;

&lt;p&gt;
I already tryed to use the ISR and the modified getkey and putchar
functions in periph.c&lt;/p&gt;

&lt;p&gt;
Program hangs and cannot enumerate on USB.&lt;/p&gt;

Look at the example in the downloads section.&lt;/p&gt;
