Embedded System

Happy news for embedded developers, with the introduction of BeagleBone Black credit card sized single board 1GHz computer.We can develop high end embedded system with Operating system support in the ARM7 platform.Processor from Texas Instruments AM335x Cortex A8 Sitara . Advantage of this small system is many more ,it will operate on 5V dc supply with 500 MA,so with USB cable connected to 5v source can operate the system.Most of the desktop computer features available with this board.As a standalone system keyboard and mouse can be connected with USB.Out put display available at micro HDMI port,that can be connected to any latest TV with HDMI input.LAN port is provided for network access.USB device(slave) port also available for connecting with PC,the board will act as storage device.Same time there is an internet pass-through via USB.For the starting of development some startup file provided in the eMMC (on board flash memmory 2GB),by opening the file it will direct to beagleb

ANDROID Android is an intermediate platform software developed for Mobile hardware by Google lead OHA (open handset alliance).It is a layer of GUI and framework between core operating system Linux and java based application programme.Android provides libraries for easy application development.We can access almost all hardware units available in the Mobile hardware (GPS ,GPRS,WiFi,Bluetooth,Camera,Flash,Screen,Mic,Speaker,etc)with less programming struggle.Google released free Software Development Kit (SDK) with emulator for the application development and testing. 2005 Google announced Android 2007 OHA formed. 2008 T.Mobile G1 produced,           Android Market for Applications          Source code of Android is released. 2011 May -google Android made its first major/official deviation from the mobile only approach by comming   out  with Android 3.0 (Honeycomb).custom made for Tablet devices.This aims to use Android system for non-mobile embedded devices. Android 3.0 (

Next generation Internet is " Internet of Things " , connecting everything with net . Data exchanging between these devices will be supported by Cloud network system . Now COSM (earlier it was Pachube ) is a free cloud provider for live data exchange, mainly from live sensors as public feed or private feed. They are providing APIs for data communication over the net through COSM services.After free signing up with COSM you can create FEED with ID and Data streams.Under a single FEED ID you can add many number of Data streams.You can update the FEED by some regular intervals automatically with ready made applications ( Android based applications are available in the google market , PC based applications also available) or user applications.A link for sample feed from my smartHome project.The data is live from sensors installed in the smartHome ( Android based system for Integrated Home Automation) . https://api.cosm.com/v2/feeds/66509/datastreams/1.png?width=730&height=

In addition to the TV viewing we can run the applications in smart TV .It should be connected with network(Internet).Web based small applications can run.Applications are installed in TV via the Internet (via LAN in the application developing stage , that is called user application).Run the application on Application Engine.I tested the features of Samsung Smart TV 2012 . Application engine actually a dedicated web browser in the smart tv. Applications are web pages (HTML pages,CSS file and Java Script).TV screen is used as the monitor (resolution is 1280x720 or 960x540).Entire screen or part of the screen can be used for the application output.The interfacing/hardware features are based on models of TV. Most of the models having USB,WIFI dongle (dedicated USB port for plug in the dongle),Ethernet LAN,HDMI inputs,DVI input,Component and Composite Video Input, RF input. Keyboard and Mouse can be connected to USB. Mass storage (Pen drive) can be connected as media storage for playing
