ir-attx4

#Infrared Driver for the ir-attx4 Tessel infrared module. The hardware documentation for this module can be found here.

If you run into any issues you can ask for support on the IR Module Forums.

###Installation

npm install ir-attx4

###Example

/*********************************************
This infrared module example transmits the
power signal sequence of an Insignia brand
television every three seconds, while also
listening for (and logging) any incoming
infrared data.
*********************************************/

var tessel = require('tessel');
var infraredlib = require('ir-attx4');
var infrared = infraredlib.use(tessel.port['A']); 

// When we're connected
infrared.on('ready', function() {
  if (!err) {
    console.log("Connected to IR!");
    // Start sending a signal every three seconds
    setInterval(function() {
      // Make a buffer of on/off durations (each duration is 16 bits)
      var powerBuffer = new Buffer([0, 178, 255, 168, 0, 12, 255, 246, 0, 13, 255, 225, 0, 13, 255, 224, 0, 12, 255, 246, 0, 12, 255, 246, 0, 13, 255, 247, 0, 13, 255, 247, 0, 13, 255, 224, 0, 12, 255, 224, 0, 13, 255, 247, 0, 13, 255, 224, 0, 12, 255, 246, 0, 12, 255, 246, 0, 12, 255, 246, 0, 12, 255, 246, 0, 13, 255, 247, 0, 13, 255, 224, 0, 12, 255, 224, 0, 13, 255, 225, 0, 13, 255, 224, 0, 12, 255, 246, 0, 12, 255, 246, 0, 13, 255, 247, 0, 13, 255, 247, 0, 13, 255, 246, 0, 12, 255, 246, 0, 12, 255, 246, 0, 12, 255, 246, 0, 12, 255, 224, 0, 13, 255, 224, 0, 12, 255, 224, 0, 12, 255, 224, 0, 12]);
      // Send the signal at 38 kHz
      infrared.sendRawSignal(38, powerBuffer, function(err) {
        if (err) {
          console.log("Unable to send signal: ", err);
        } else {
          console.log("Signal sent!");
        }
      });
    }, 3000); // Every 3 seconds
  } else {
    console.log(err);
  }
});

// If we get data, print it out
infrared.on('data', function(data) {
	console.log("Received RX Data: ", data);
});

###Methods # infrared.sendRawSignal( frequency, signalDurations, callback )
The primary method for sending data. The first argument is a frequency of signal in Hz, typically 38 but can range from 36 to 40. The second argument is a buffer of unsigned 16 bit integers representing the number of microseconds the transmission should be on. The max length of the signal durations is 100 durations.

# infrared.setListening( set, callback )
Determines whether the module is listening for incoming signals. Will automatically be set and unset depending on listeners for the data event.

###Events # infrared.on( 'data', callback(data) )
Emitted when an infrared signal is detected.

# infrared.on( 'error', callback(err) )
Emitted when there is an error communicating with the module.

# infrared.on( 'ready', callback() )
Emitted upon first successful communication between the Tessel and the module.
