* @author Christoph Bartelmus
* @ingroup driver_api
*
* Operations in this module applies to the transmit buffer. The buffer
* is initiated using send_buffer_init(), filled with data using send_buffer_put()
* and accessed using send_buffer_data() and send_buffer_length().
*
* A prepared buffer contains an even number of unsigned ints, each of
* which representing a pulse width in microseconds. The first item represents
* a pulse and the last thus a space.
