-====== BBC micro:bit ======
-//Taken from the official DroidScript documentation with some more texts and API documentation.//
-=====Getting Started=====
-//:!: Please make sure you have the Espruino firmware file installed on your micro:bit before trying to use this plugin. See [[http://www.microbit-js.org]] for more details.//
-//:!: You have to install the plugin over the plugin section within DroidScript//
-=====Using the BBC micro:bit Plugin=====
-In order to use the micro:bit, you must first load the plugin at the top of your script using the **LoadPlugin** method like this:
-<code>app.LoadPlugin( "MicroBit" );</code>
-Then you can create the microbit object like this:
-<code>microbit = app.CreateMicroBit();</code>
-You will need to connect to your micro:bit using Bluetooth and you can scan for it like this:
-<code>microbit = microbit.Scan();</code>
-=====Examples=====
-====Example - Send smiley face click to collapse contents ====
-<code javascript>
-app.LoadPlugin( "MicroBit" );
-function OnStart()
-{
-  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
-  btn = app.CreateButton( "Smile" );
-  btn.SetOnTouch( btn_OnTouch );
-  lay.AddChild( btn );
-  app.AddLayout( lay );
-  microbit = app.CreateMicroBit();
-  microbit.Scan();
-}
-function btn_OnTouch()
-{
-  microbit.SetLEDs( "0111010001001000010010001" );
-}
-</code>
-====Example - Send scrolling texts====
-<code javascript>
-app.LoadPlugin( "MicroBit" );
-function OnStart()
-{
-  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
-  btn = app.CreateButton( "Send" );
-  btn.SetOnTouch( btn_OnTouch );
-  lay.AddChild( btn );
-  app.AddLayout( lay );
-  microbit = app.CreateMicroBit();
-  microbit.Scan();
-}
-function btn_OnTouch()
-{
-  microbit.ScrollText( "Hello", 150 );
-}
-</code>
-If you want to receive messages from your micro:bit, then you will need to create a function to be called when new messages are available (a callback function). You can set the name of your function like this:
-<code javascript>
- microbit.SetOnReceive( MyFunc );
-</code>
-====Example - Detect button presses click to collapse contents====
-<code javascript>
-app.LoadPlugin( "MicroBit" );
-function OnStart()
-{
-  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
-  txt = app.CreateText( "Press a button on your micro:bit" );
-  lay.AddChild( txt );
-  app.AddLayout( lay );
-  microbit = app.CreateMicroBit();
-  microbit.SetOnConnect( OnConnect );
-  microbit.Scan();
-}
-function OnConnect()
-{
-  microbit.SetOnButton( OnButton );
-}
-function OnButton( name, state )
-{
-  txt.SetText( name + " : " + state );
-}
-</code>
-====Example - Detect movement click to collapse contents====
-<code javascript>
-app.LoadPlugin( "MicroBit" );
-function OnStart()
-{
-  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
-  txt = app.CreateText( "Move your micro:bit" );
-  lay.AddChild( txt );
-  app.AddLayout( lay );
-  microbit = app.CreateMicroBit();
-  microbit.SetOnConnect( OnConnect );
-  microbit.Scan();
-}
-function OnConnect()
-{
-  microbit.SetOnMotion( OnMotion );
-}
-function OnMotion( x, y, z )
-{
-  txt.SetText( x + "," + y + "," + z );
-}
-</code>
-You can also send programs to the micro:bit and have them run every time the micro:bit is powered up using the following methods (Advanced).
-<code javascript>
- microbit.SendCode( code );
- microbit.Save();
-</code>
-See http://www.espruino.com/MicroBit for more code samples that can be run directly on the micro:bit
-bit
-====Example - Save code on the micro:bit click to collapse contents====
-<code javascript>
-app.LoadPlugin( "MicroBit" );
-function OnStart()
-{
-  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
-  var code = "var text = 'Fred Blogs';\n" +
-  "g = Graphics.createArrayBuffer(5,5,1);\n" +
-  "g.flip = function(){show(this.buffer);};\n" +
-  "var x = 0;\n" +
-  "\n" +
-  "function draw()\n" +

-  "g.flip();\n" +
-  "}\n" +
