<h1>UART Library</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
Interrupt UART library using the built-in UART with transmit and receive circular buffers.
<p>
<div class="fragment"><pre class="fragment"><span class="preprocessor"> #include <uart.h></span>
</pre></div><p>
This library can be used to transmit and receive data through the built in UART.<p>
An interrupt is generated when the UART has finished transmitting or receiving a byte. The interrupt handling routines use circular buffers for buffering received and transmitted data.<p>
The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE constants define the size of the circular buffers in bytes. Note that these constants must be a power of 2. You may need to adapt this constants to your target and your application by adding CDEFS += -DUART_RX_BUFFER_SIZE=nn -DUART_RX_BUFFER_SIZE=nn to your Makefile.<p>
