Anyway since I can't get any help with the Serial...
I attempting a different method for triggering sound from the MP3 Trigger. The MP3 trigger has pins where if you ground them, then that track is played. I am trying to get the Arduino to set a pin LOW to trigger the sound. But I cannot get it to work in the EasyVR sketch.
#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#include "SoftwareSerial.h"
SoftwareSerial port(12,13);
#else // Arduino 0022 - use modified NewSoftSerial
#include "WProgram.h"
#include "NewSoftSerial.h"
NewSoftSerial port(12,13);
#endif
#include "EasyVR.h"
EasyVR easyvr(port);
int pin = 6;
int pin2 = 8;
int pin3 = 9;
//Groups and Commands
enum Groups
{
GROUP_0 = 0,
GROUP_1 = 1,
};
enum Group0
{
G0_MICA = 0,
};
enum Group1
{
G1_HELLO = 0,
G1_HOW_ARE_YOU = 1,
};
EasyVRBridge bridge;
int8_t group, idx;
void setup()
{
pinMode(pin,OUTPUT);
// bridge mode?
if (bridge.check())
{
cli();
bridge.loop(0, 1, 12, 13);
}
// run normally
Serial.begin(9600);
port.begin(9600);
if (!easyvr.detect())
{
Serial.println("EasyVR not detected!");
for (;;);
}
easyvr.setPinOutput(EasyVR::IO1, LOW);
Serial.println("EasyVR detected!");
easyvr.setTimeout(5);
easyvr.setLanguage(0);
group = EasyVR::TRIGGER; //<-- start group (customize)
}
void action();
void loop()
{
digitalWrite(pin,HIGH);
easyvr.setPinOutput(EasyVR::IO1, HIGH); // LED on (listening)
Serial.print("Say a command in Group ");
Serial.println(group);
easyvr.recognizeCommand(group);
do
{
// can do some processing while waiting for a spoken command
}
while (!easyvr.hasFinished());
easyvr.setPinOutput(EasyVR::IO1, LOW); // LED off
idx = easyvr.getWord();
if (idx >= 0)
{
// built-in trigger (ROBOT)
// group = GROUP_X; <-- jump to another group X
return;
}
idx = easyvr.getCommand();
if (idx >= 0)
{
// print debug message
uint8_t train = 0;
char name[32];
Serial.print("Command: ");
Serial.print(idx);
if (easyvr.dumpCommand(group, idx, name, train))
{
Serial.print(" = ");
Serial.println(name);
}
else
Serial.println();
easyvr.playSound(0, EasyVR::VOL_FULL);
// perform some action
action();
}
else // errors or timeout
{
if (easyvr.isTimeout())
Serial.println("Timed out, try again...");
int16_t err = easyvr.getError();
if (err >= 0)
{
Serial.print("Error ");
Serial.println(err, HEX);
}
}
}
void action()
{
switch (group)
{
case GROUP_0:
switch (idx)
{
case G0_MICA:
//digitalWrite(pin,LOW);
//digitalWrite(pin,HIGH);
group = GROUP_1; //<-- or jump to another group X for composite commands
break;
}
break;
case GROUP_1:
switch (idx)
{
case G1_HELLO:
digitalWrite(pin,LOW);
//digitalWrite(pin,HIGH);
//group = GROUP_X; <-- or jump to another group X for composite commands
break;
case G1_HOW_ARE_YOU:
// group = GROUP_X; <-- or jump to another group X for composite commands
break;
}
break;
}
}
When I say "Hello," the pin is supposed to ground and trigger the sound. But it doesn't.
case G1_HELLO:
digitalWrite(pin,LOW);
//digitalWrite(pin,HIGH);
//group = GROUP_X; <-- or jump to another group X for composite commands
break;
It only triggers a sound at power on or reset because of this piece:
void setup()
{
pinMode(pin,OUTPUT);
// bridge mode?
if (bridge.check())
....
....
There is a digitalWrite(pin,HIGH) at the start of the loop since I do not want the pin to stay at 0v/ground. Anyone have a hint as to what I am doing wrong?
