hello, I working on my project and I'm using EasyVR speech recognition module on Arduino. I'm a newbie in programming code.
in EasyVR code, what is the purpose of this code? --->
EasyVRBridge bridge;
int8_t group, idx;
void setup()
{
pinMode(pin8, OUTPUT);
pinMode(pin4, 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()
{
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)
{
count++;
easyvr.playSound(1, EasyVR::VOL_FULL);
Serial.print("Error ");
Serial.println(err, HEX);
}
if (count == 3) //if 3 errors are sent do something
{
group = GROUP_0;
switch (idx)
{
case G0_COMPUTER:
group = GROUP_1;
}
count = 0;
