*
|
||||
* @brief Interrupt UART library using the built-in UART with transmit and receive circular buffers.
|
||||
* @see README.md
|
||||
*
|
||||
* This library can be used to transmit and receive data through the built in UART.
|
||||
*
|
||||
* 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.
|
||||
*
|
||||
* The UART_RXn_BUFFER_SIZE and UART_TXn_BUFFER_SIZE constants define
|
||||
* the size of the circular buffers in bytes. Note that these constants must be a power of 2.
|
||||
*
|
||||
* You need to define these buffer sizes as a symbol in your compiler settings or in uart.h
|
||||
*
|
||||
* See README.md for more detailed information. Especially that relating to symbols: USARTn_ENABLED and USARTn_LARGE_BUFFER
|
||||
