accel-mma84

#Accelerometer Driver for the accel-mma84 Tessel accelerometer module (MMA8452Q).

##Installation

npm install accel-mma84

##Example

// var hardware = require('hardware');
var tessel = require('tessel');
console.log("Connecting to accelerometer on port bank A");
var accel = require('accel-mma84').use(tessel.port("A"));

// Initialize the accelerometer.
accel.on('ready', function () {
  // Stream accelerometer data
  accel.on('data', function (xyz) {
    console.log("x:", xyz[0].toFixed(2),
      "y:", xyz[1].toFixed(2),
      "z:", xyz[2].toFixed(2));
  });
});

accel.on('error', function(err) {
  console.log("Unable to connect to module: ", err);
})

##Methods

• accel.getAcceleration(callback(err, xyz))

• accel.setOutputRate(rateInHz, callback(err, xyz))

• accel.availableOutputRates()

• accel.setScaleRange(scaleRange, callback(err, xyz))

• accel.availableScaleRanges()

##Events

• ready

• error

• data

##Further Examples

• Average (more advanced use)
