Projektlabor Robotik MINTgrün

Ein simpler Schaltplan für das Modul ist in der Dokumentation unter https://www.parallax.com/sites/default/files/downloads/30016-Emic-2-Text-To-Speech-Documentation-v1.1.pdf zu finden. Sobald alles verkabelt ist könnt ihr dieses Beispielsprogramm testen:

// include the SoftwareSerial library so we can use it to talk to the Emic 2 module
#include <SoftwareSerial.h>
 
#define rxPin   10  // Serial input (connects to Emic 2's SOUT pin)
#define txPin   11  // Serial output (connects to Emic 2's SIN pin)
#define ledPin  13  // Most Arduino boards have an on-board LED on this pin
 
// set up a new serial port
SoftwareSerial emicSerial =  SoftwareSerial(rxPin, txPin);
 
void setup()  // Set up code called once on start-up
{
  // define pin modes
  pinMode(ledPin, OUTPUT);
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
 
  // set the data rate for the SoftwareSerial port
  emicSerial.begin(9600);
 
  digitalWrite(ledPin, LOW);  // turn LED off
 
  /*
    When the Emic 2 powers on, it takes about 3 seconds for it to successfully
    initialize. It then sends a ":" character to indicate it's ready to accept
    commands. If the Emic 2 is already initialized, a CR will also cause it
    to send a ":"
  */
  emicSerial.print('\n');             // Send a CR in case the system is already up
  while (emicSerial.read() != ':');   // When the Emic 2 has initialized and is ready, it will send a single ':' character, so wait here until we receive it
  delay(10);                          // Short delay
  emicSerial.flush();                 // Flush the receive buffer
}
 
void loop()  // Main code, to run repeatedly
{
  emicSerial.print('V');
  emicSerial.print("0");  // Set volume to 0dB (range -48dB (soft) to 18dB (loud))
  emicSerial.print('\n');
  digitalWrite(ledPin, HIGH);         // Turn on LED while Emic is outputting audio
  while (emicSerial.read() != ':');   // Wait here until the Emic 2 responds with a ":" indicating it's ready to accept the next command
  digitalWrite(ledPin, LOW);
  // Every robot should inherit the three laws of robotics!
  // 1. Law of robotics
  emicSerial.print('S');
  emicSerial.print("A robot may not injure a human being or, through inaction, allow a human being to come to harm.");  // Send the desired string to convert to speech
  emicSerial.print('\n');
  digitalWrite(ledPin, HIGH);         // Turn on LED while Emic is outputting audio
  while (emicSerial.read() != ':');   // Wait here until the Emic 2 responds with a ":" indicating it's ready to accept the next command
  digitalWrite(ledPin, LOW);
  // 2. Law of robotics
  emicSerial.print('S');
  emicSerial.print("A robot must obey the orders given it by human beings, except where such orders would conflict with the First Law.");  // Send the desired string to convert to speech
  emicSerial.print('\n');
  digitalWrite(ledPin, HIGH);         // Turn on LED while Emic is outputting audio
  while (emicSerial.read() != ':');   // Wait here until the Emic 2 responds with a ":" indicating it's ready to accept the next command
  digitalWrite(ledPin, LOW);
  // 3. Law of robotics
  emicSerial.print('S');
  emicSerial.print("A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.");  // Send the desired string to convert to speech
  emicSerial.print('\n');
  digitalWrite(ledPin, HIGH);         // Turn on LED while Emic is outputting audio
  while (emicSerial.read() != ':');   // Wait here until the Emic 2 responds with a ":" indicating it's ready to accept the next command
  digitalWrite(ledPin, LOW);
 
  delay(5000);
}

Hier ist eine Liste von Befehlen, mit welchen man die Einstellungen ändern kann, z.B. die Sprache (Englisch / Spanisch), Stimme, Lautstärke usw.: http://bradsduino.blogspot.de/2013/04/emic-2-text-to-speech-module-arduino-due.html. Ein Beispiel, wie man die Lautstärke mit solchen Befehlen ändert, ist bereits im Code oben erhalten. Die Sprache kann man z.B. so ändern:

  emicSerial.print("L2"); // fuer lateinamerikanisches Spanisch
  emicSerial.print('\n');
