|
<p>Interrupt UART library using the built-in UART with transmit and receive circular buffers. </p>
|
|
<div class="fragment"><div class="line"><span class="preprocessor">#include <<a class="code" href="uart_8h.html">uart.h</a>></span> </div>
|
|
</div><!-- fragment --><p>This library can be used to transmit and receive data through the built in UART.</p>
|
|
<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>
|
|
<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 these constants to your target and your application by adding CDEFS += -DUART_RX_BUFFER_SIZE=nn -DUART_TX_BUFFER_SIZE=nn to your Makefile.</p>
