+OLED JS Pi over i2c-bus
+========================
+
+## What is this?
+
+This is fork of package [`oled-js-pi`](https://github.com/kd7yva/oled-js-pi) that works thru `i2c-bus` package and not use package `i2c`.
+
+A NodeJS driver for I2C/SPI compatible monochrome OLED screens; to be used on the Raspberry Pi! Works with 128 x 32, 128 x 64 and 96 x 16 sized screens, of the SSD1306 OLED/PLED Controller (read the [datasheet here](http://www.adafruit.com/datasheets/SSD1306.pdf)).
+
+This based on the Blog Post and code by Suz Hinton - [Read her blog post about how OLED screens work](http://meow.noopkat.com/oled-js/)!
+
+OLED screens are really cool - now you can control them with JavaScript!
+
+## Install
+
+If you haven't already, install [NodeJS](http://nodejs.org/).
+
+`npm install oled-i2c-bus`
+
+## I2C screens
+Hook up I2C compatible oled to the Raspberry Pi. Pins: SDL and SCL
+
+### I2C example
+
+```javascript
+var i2c = require('i2c-bus'),
+  i2cBus = i2c.openSync(1),
+  oled = require('oled-i2c-bus');
+
+var opts = {
+  width: 128,
+  height: 64,
+  address: 0x3D
+};
+
+var oled = new oled(i2cBus, opts);
+
+// do cool oled things here
+
+```
+
+### Wait, how do I find out the I2C address of my OLED screen?
+Check your screen's documentation...
+
+## Available methods
+
+### clearDisplay
+Fills the buffer with 'off' pixels (0x00). Optional bool argument specifies whether screen updates immediately with result. Default is true.
+
+Usage:
+```javascript
+oled.clearDisplay();
+```
+
+### dimDisplay
+Lowers the contrast on the display. This method takes one argument, a boolean. True for dimming, false to restore normal contrast.
+
+Usage:
+```javascript
+oled.dimDisplay(true|false);
+```
+
+### invertDisplay
+Inverts the pixels on the display. Black becomes white, white becomes black. This method takes one argument, a boolean. True for inverted state, false to restore normal pixel colors.
+
+Usage:
+```javascript
+oled.invertDisplay(true|false);
+```
+
+### turnOffDisplay
+Turns the display off.
+
+Usage:
+```javascript
+oled.turnOffDisplay();
+```
+
+### turnOnDisplay
+Turns the display on.
+
+Usage:
+```javascript
+oled.turnOnDisplay();
+```
+
+
+### drawPixel
+Draws a pixel at a specified position on the display. This method takes one argument: a multi-dimensional array containing either one or more sets of pixels.
+
+Each pixel needs an x position, a y position, and a color. Colors can be specified as either 0 for 'off' or black, and 1 or 255 for 'on' or white.
+
+Optional bool as last argument specifies whether screen updates immediately with result. Default is true.
+
+Usage:
+```javascript
+// draws 4 white pixels total
+// format: [x, y, color]
+oled.drawPixel([
+	[128, 1, 1],
+	[128, 32, 1],
+	[128, 16, 1],
+	[64, 16, 1]
+]);
+```
+
+### drawLine
+Draws a one pixel wide line.
+
+Arguments:
+ int **x0, y0** - start location of line
+ int **x1, y1** - end location of line
+ int **color** - can be specified as either 0 for 'off' or black, and 1 or 255 for 'on' or white.
+
+Optional bool as last argument specifies whether screen updates immediately with result. Default is true.
+
+Usage:
+```javascript
+// args: (x0, y0, x1, y1, color)
+oled.drawLine(1, 1, 128, 32, 1);
+```
+
+### fillRect
+Draws a filled rectangle.
+
+Arguments:
+ int **x0, y0** - top left corner of rectangle
+ int **w, h** - width and height of rectangle
+ int **color** - can be specified as either 0 for 'off' or black, and 1 or 255 for 'on' or white.
+
+Optional bool as last argument specifies whether screen updates immediately with result. Default is true.
+
+Usage:
+```javascript
+// args: (x0, y0, x1, y1, color)
+oled.fillRect(1, 1, 10, 20, 1);
+```
+
+### drawBitmap
+Draws a bitmap using raw pixel data returned from an image parser. The image sourced must be monochrome, and indexed to only 2 colors. Resize the bitmap to your screen dimensions first. Using an image editor or ImageMagick might be required.
+
+Optional bool as last argument specifies whether screen updates immediately with result. Default is true.
+
+Tip: use a NodeJS image parser to get the pixel data, such as [pngparse](https://www.npmjs.org/package/pngparse). A demonstration of using this is below.
+
+
+Example usage:
+```
+npm install pngparse
+```
+
+```javascript
+var pngparse = require('pngparse');
+
+pngparse.parseFile('indexed_file.png', function(err, image) {
+	oled.drawBitmap(image.data);
+});
+```
+
+This method is provided as a primitive convenience. A better way to display images is to use NodeJS package [png-to-lcd](https://www.npmjs.org/package/png-to-lcd) instead. It's just as easy to use as drawBitmap, but is compatible with all image depths (lazy is good!). It will also auto-dither if you choose. You should still resize your image to your screen dimensions. This alternative method is covered below:
+
+```
+npm install png-to-lcd
+```
+
+```javascript
+var pngtolcd = require('png-to-lcd');
+
+pngtolcd('nyan-cat.png', true, function(err, bitmap) {
+  oled.buffer = bitmap;
+  oled.update();
+});
+```
+
+### drawRGBAImage
+Draw an RGBA coded image at specific coordinates. This only supports a monochrome
+OLED so transparent pixels must be 100% transparent, off pixels should have an
+RGB value of (0, 0, 0), and pixels with any color value will be considered on.
+
+Use a library such as [pngjs](https://www.npmjs.com/package/pngjs) to read a png
+file into the required rgba data structure.
+
+Example:
+```JavaScript
+const fs = require('fs');
+const PNG = require('pngjs').PNG;
+const i2c = require('i2c-bus');
+const oled = require('oled-i2c-bus');
+
+var i2cBus = i2c.openSync(0);
+
+var opts = {
+  width: 128,
+  height: 64,
+  address: 0x3C
+};
+
+var display = new oled(i2cBus, opts);
+
+display.clearDisplay();
+display.turnOnDisplay();
+
+fs.createReadStream('./test.png')
+.pipe(new PNG({ filterType: 4 }))
+.on('parsed', function () {
+  setInterval(() => { drawImage(this) }, 1000);
+});
+
+function drawImage(image) {
+  let x = Math.floor(Math.random() * (display.WIDTH) - image.width / 2);
+  let y = Math.floor(Math.random() * (display.HEIGHT) - image.height / 2);
+  display.drawRGBAImage(image, x, y);
+}
+```
+
+
+### startScroll
+Scrolls the current display either left or right.
+Arguments:
+ string **direction** - direction of scrolling. 'left' or 'right'
+ int **start** - starting row of scrolling area
+ int **stop** - end row of scrolling area
+
+Usage:
+```javascript
+// args: (direction, start, stop)
+oled.startscroll('left', 0, 15); // this will scroll an entire 128 x 32 screen
+```
+
+### stopScroll
+Stops all current scrolling behaviour.
+
+Usage:
+```javascript
+oled.stopscroll();
+```
+
+### setCursor
+Sets the x and y position of 'cursor', when about to write text. This effectively helps tell the display where to start typing when writeString() method is called.
+
+Call setCursor just before writeString().
+
+Usage:
+```javascript
+// sets cursor to x = 1, y = 1
+oled.setCursor(1, 1);
+```
+
+### writeString
+Writes a string of text to the display.  
+Call setCursor() just before, if you need to set starting text position.
+
+Arguments:
+ obj **font** - font object in JSON format (see note below on sourcing a font)
+ int **size** - font size, as multiplier. Eg. 2 would double size, 3 would triple etc.
+ string **text** - the actual text you want to show on the display.
+ int **color** - color of text. Can be specified as either 0 for 'off' or black, and 1 or 255 for 'on' or white.
+ bool **wrapping** - true applies word wrapping at the screen limit, false for no wrapping. If a long string without spaces is supplied as the text, just letter wrapping will apply instead.
+
+Optional bool as last argument specifies whether screen updates immediately with result. Default is true.
+
+Before all of this text can happen, you need to load a font buffer for use. A good font to start with is NodeJS package [oled-font-5x7](https://www.npmjs.org/package/oled-font-5x7).
+
+Usage:
+```
+npm install oled-font-5x7
+```
+
+```javascript
+var font = require('oled-font-5x7');
+
+// sets cursor to x = 1, y = 1
+oled.setCursor(1, 1);
+oled.writeString(font, 1, 'Cats and dogs are really cool animals, you know.', 1, true);
+```
+
+### update
+Sends the entire buffer in its current state to the oled display, effectively syncing the two. This method generally does not need to be called, unless you're messing around with the framebuffer manually before you're ready to sync with the display. It's also needed if you're choosing not to draw on the screen immediately with the built in methods.
+
+Usage:
+```javascript
+oled.update();
+```
