Node.js HMC6343 3-Axis Magnetometer Module

This module allows your code to interogate the HMC6343 magnetometer via the I2C bus.

Installation

Install the module with

npm install hmc6343

Usage

Basic usage can be found in main.js...

//include the module
var hmc6343 = require('hmc6343');

//create new instance. Arguments are the i2c device to which the HMC6343 is connected and its 7-bit address (0x19 by default)
var compass = new hmc6343('/dev/i2c-3', 0x19);

//read in accelerometer data
compass.readAccel(function(accelData) {
	console.log("Accel Data: " + accelData.ax + ", " + accelData.ay + ", " + accelData.az);
});

//read in magnetic data
compass.readMag(function(magData) {
	console.log("Mag Data: " + magData.mx + ", " + magData.my + ", " + magData.mz);
});

//read in attitude data (in radians)
compass.readAtt(function(attData) {
	console.log("Attitude: " + attData.heading + ", " + attData.pitch + ", " + attData.roll);
});
