Advanced tools
#Accelerometer Driver for the accel-mma84 Tessel accelerometer module (MMA8452Q).
##Installation
npm install accel-mma84
##Example
/*********************************************
This basic accelerometer example logs a stream
of x, y, and z data from the accelerometer
*********************************************/
var tessel = require('tessel');
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('error connecting', err);
});
setInterval(function(){}, 20000);
##Methods
accel.availableOutputRates()
Logs the available interrupt rates in Hz.accel.availableScaleRanges()
Logs the available accelerometer ranges (in units of Gs).accel.enableDataInterrupts(trueOrFalse, callback(err))
Enables or disables data interrupts. Set the first param truthy to enable, falsy to disable.accel.getAcceleration(callback(err, xyz))
Gets the acceleration from the device, outputs as array [x, y, z].accel.setOutputRate(rateInHz, callback(err))
Sets the output rate of the data (1.56-800 Hz).accel.setScaleRange(scaleRange, callback(err))
Sets the accelerometer to read up to 2, 4, or 8 Gs of acceleration (smaller range = better precision).##Events
accel.on('data', callback(xyz))
Emitted when data is available. xyz
is an array in the form of [x, y, z].accel.on('error', callback(err))
Emitted upon error.accel.on('ready', callback())
Emitted upon first successful communication between the Tessel and the module.##Further Examples See the examples folder for code.
show-axes: Manipulate LEDs based on acceleration in the three axes.
change-rates: Change the polling rate.
