$3

Linux and *nix systems may require sudo to access the hid device interface.

*Not tested on all platforms.
Platform tests appreciated

``javascript
// require the LED module
var keyboard = require('msi-keyboard')();

// Set left region to high intensity, color red
keyboard.color('left', {
color: 'red',
intensity: 'high'
});

// Set middle region to green default high intensity
keyboard.color('middle', 'green');


// Set right region to blue with light intensity
keyboard.color('right', {
color: 'blue',
intensity: 'light',
});


// Hardware modes
// Setting .color() will Not affect the hardware defined colors for modes

// Set Hardware mode to breath
keyboard.mode('breathe', 'green');


// Blinking
// Set the keyboard.color() Before calling .blink()
// Refer to examples/blinkMulti.js

// Blink all the keyboard LEDs to 750ms
keyboard.blink(750);


// Blink Only left and right regions at 750ms
keyboard.blink(['left','right'], 750);


// Use the default blink, time: 1000ms
keyboard.blink();


// Stop the blink after 5000ms
setTimeout(keyboard.stopBlink, 5000);

`

Colors


keyboard.colors(String region, String Color);

Colors must be set before using keyboard.blink();

They will not affect hardware-default modes such as Wave and Breathing.

All colors supported by Colors.js are now supported here

To set a color use keyboard.colors() There are two ways to set the color to a region:
`javascript
keyboard.color('middle', 'green');
keyboard.color('middle', {color:'#ffffff', intensity:'high'});
keyboard.color('middle', {color:'#4654BD', intensity:'high'});
`




Intensity


keyboard.colors(String region, {String color, String intensity});

The color intensity to white can be set via keyboard.colors();

The following intensities are used:

light
low
med
high

To set it:

`javascript
keyboard.color('right', {
color: '#1CA626',
intensity: 'med', // light, low, med, high
});
`

##Modes
keyboard.mode(String mode, String primaryColor, String secondaryColor);
keyboard.mode(String mode, Object left, Object middle, Object right, Integer cyclePeriod);

MSI Steelseries keyboards have built modes.

Breathe and Wave modes support fading between colors, which can be set when calling the keyboard.mode() method.

Passing in only one color argument defaults the secondaryColor to 'black':

keyboard.mode(String mode, String primaryColor);

You can also set each region's color individually:

keyboard.mode(String mode, String leftPrimary, String middlePrimary, String rightPrimary, Integer cyclePeriod);

keyboard.mode(String mode, Object left, Object middle, Object right, Integer cyclePeriod);

Region objects are defined as such:

right: {
primary: {
color: 'red',
intensity: 'high'
},
secondary: {
color: 'blue',
intensity: 'high'
}
}

Which is equivalent to:

right: {
color: 'red',
intensity: 'high',
secondary: {
color: 'blue',
intensity: 'high'
}
}


You can also define just the primary and secondary colors, leaving the intensities to their default (high):

right: {
primary: 'red',
secondary: 'blue'
}

If you specify the color and intensity directly in the Region object, you can set just one of the secondary fields and the other will take the default from the primary (secondary color will be red with light intensity):

right: {
color: 'red',
intensity: 'high',
secondary: {intensity:'light'}
}

The cyclePeriod defaults to 2 seconds when not passed in.

The modes defined by the hardware are:

Normal
Gaming
Breathe
Demo
Wave


Usage:

`javascript

keyboard.mode('breathe', 'green', 'red', 'yellow');

`


##Regions
keyboard.colors(String region, String color);

There are three regions on the Steelseries keyboard:

Left
Middle
Right

Each can have a color and intensity set.

##Blink
keyboard.blink(Time milliseconds);

The time is the speed in which the keyboard is to blink.

keyboard.colors(); Must be set before using keyboard.blink();

Usage:

`javascript
// keyboard.color(...);


keyboard.blink(750);
`

To blink one, or two regions only:

`javascript
// keyboard.color(...);


keyboard.blink(['left','right'], 750);
`
