Detailed Description

an EMIC #36000 TTY text to speech unit

The oTTSemic object allows the conversion of text to speech using the Emic #36000 module.

Operation

Note that since the binary transmits a 0x0 character, the ASCII mode was used to be on the safe side. Pretty straight forward really.

Remarks

Module installs easily, the only catch is you have to send a hard or soft reset before using the board. Also, for some reason, after a soft reset, I get an "OK" acknowledge followed by an "ERROR" acknowledge. Haven't tracked down why this is. Skirted the issue with the get_any_ack method which eats up any response after a reset command.

Sample Code

#include <hardware/oled.h>
#include <oconsole.h>
#include "ottsemic.h"
oConsole console;
oTTSemic  emic(8,9);
char RXbuff[251];
char TXbuff[251];
oGreenLED green;
oRedLED red;
// -----------------------------------------------------------------
// MAIN
// -----------------------------------------------------------------
int main()
{
char c;
  red.off();
  green.on();
  console.buffer(&RXbuff[0],250,&TXbuff[0],250);
  console.syncronize();
  emic.reset();
bool  done = false;
  while (!done)
  {
    emic.say("Hello.  My name is Daisy.  What is you're name?");
    console.echo("x to exit; anything else to repeat\n");
    c = console.get();
    if (c == 'x') done = true;
  } 
  emic.say("goodbye");
  console.echo("done");
  green.off();
  red.on();
  for (int i=0; i<190000; i++);
  exit(0);
}

Constructor & Destructor Documentation

oTTSemic (  IOLINE  rx, IOLINE  tx )

Member Function Documentation

bool say (  const char *const  icommand  )

wrapper for say command. Note: Do NOT put an receive_ack with this command. The wrapper performs this function.

void send_command (  const char *const  icommand, const char *const  iparm )

transmits an ASCII emic command. Parameters: icommand  : emic command to transmit iparm  : parameter for command or NULL string ("") for none. Allows the sending of any command and parameter. For example, send_command(VOLUME,"7"); The following are the valid commands: SAY : any text RESET : no parameter. VOLUME : 0-7 (default 4) SPEED : 0-4 (default 2) PITCH : 0-6 (default 2) AUDIO : no parameter
