/*
 * Magnevation SpeakJet Speech and Sound Sythesizer Module
 * 
 * This directory contains a complete test program for demonstrating the
 * use of the Magnevation SpeakJet speach chip with the BDMICRO MAVRIC
 * and MAVRIC-II microcontroller boards.  Feel free to copy the relevent
 * function definitions into your own applications and to customize them
 * for your needs.
 * 
 * The code is written in C using the GNU GCC C Compiler.  A Makefile is
 * provided which is known to work correctly on the FreeBSD Unix
 * operating system.
 * 
 * Configuration:
 *  
 *   Hook up the SpeakJet according to its data sheet.  Attach the
 *   SpeakJet output to an amplifier.  Attach your MAVRIC or MAVRIC-II
 *   PORTD3 to SpeakJet pin 11 (Serial TTL Data).  It is important to use
 *   PORTD3 and not the MAVRIC/MAVRIC-II UART1 TX pin because the UART1
 *   TX pin is a level shifted RS232 voltage, while the SpeakJet utilizes
 *   just the TTL level.  PORTD3 on the MAVRIC/MAVRIC-II is the TTL level
 *   RS232 output pin which is the one to use with the SpeakJet.
 * 
 *   When the MAVRIC/MAVRIC-II comes out of reset, it will speak the
 *   phrase: "Welcome to the BDMICRO MAVRIC SpeakJet Test Program".
 * 
 * For more information about the MAVRIC and MAVRIC-II microcontroller
 * boards, see:
