Node_MPR121

Access the MPR121 chipset via node-i2c

Port of Adafruit_Python_MPR121 to node.js. So far tested on a beaglebone-black rev-c. But it should work on other devices as RasberryPi as well.

Example

Showing a simple loop reading the touch status every 0.1ms

``js
// get library
var MPR121 = require('mpr121');

// setup sensor device id 0x5A and i2c-bus 1
var touchsensor = new MPR121(0x5A, 1);

// initialize sensor, on success start script
if (touchsensor.begin()) {
// message how to quit
console.log('Press Ctrl-C to quit.');

// Interval for reading the sonsor
setInterval(function() {
// get touch values
var t = touchsensor.touched();

// prepare some result array
var ret = [];

// loop through pins
for (var i = 0; i < 12; i++) {
// push status into array
ret.push (touchsensor.is_touched(i));
}

// return status array
console.log(ret);

},100);
};
