My application receive data in usart1 through interrupt. 
I generated the files in STM32CubeMX for MDK-ARM. 
This error appears in the compilation: 
../Src/stm32f1xx_it.c(193): Error: # 20: identifier &amp;quot;USART_IT_RXNE&amp;quot;
is undefined.

The traditional way?&lt;/p&gt;

&lt;p&gt;
Scan the available files to search for the symbol. Figure out if
it isn&amp;#39;t seen by the compiler because you have missed an include or a
define or if there is some bug somewhere. As a workaround, the
processor documentation should contain the register definition where
you can see which bit that contains this flag.&lt;/p&gt;

&lt;p&gt;
Or look for sample UART projects for your processor and figure out
how they manage to check this flag bit.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
