Embedded System

Android  is a software stack for mobile devices created by the Google lead Open Handset Alliance  .It  includes an OS ( Linux ) , middleware, core  applications. It is device independent  platform  . You can develop  applications  for devices such as mobile phone, Tablet  PC, notebook, GPS device, Reader, Set Top Box, TV. Android applications  are developed  in Java. Android also uses XML to define various resources inside the application. Google provide Android software development kit  (SDK) .It is free and includes  compiler, debugger, device emulator, Java virtual machine (Dalvic virtual machine ). Android supports 2D and 3D  graphics using the OpenGL libraries. Data storage with open source database SQLite. Android allows  programmers to add any application of their  choice on an actual platform.

This is my first mobile  blog publishing from my first ANDROID phone ...HTC Whildfire S. It having more features  and smart performance. Android 2.3.3 Hardware features l am not mentioning here. Above the Android platform one more layer of  HTC sense  software is loaded . For Android application development HTC sync supports application download from pc

GNU RXTX for Android For communicating with other embedded devices which is having only serial port (COM).

Location Finder Unit  Modules used for the project. ARM7(LPC2148) microcontroller used as the processor GPS module with UART(3.3v TTL) interface  GSM/GPRS modem module with RS232 serial interface Power Supply(5v for ARM board GPS,7v for GSM modem) Software devoloped with Rowly Cross Studio 2.0   IDE (GNU C compiler) compiled output is in hex format,this target software is flashed to processor with Philips Flash utility. Functions:- Show the location details (Latitude,Longitude) in LCD. Simply make a ring to this unit,it will give the informations through SMS- Example -If you are using in School Bus parents can make a ring (no call charge) and get the position of School Bus. Latitude,Longitude Speed Direction Name of the location Stored information(coustomized message for individual calling numbers) Facility for storing the information for current position- Name of location To include in category list like ATM,Petrol Pump,Police Station,Hotels et...

Introduction to Android Actually android itself is not an Operating System, Inner level OS is Linux,over the linux Android is loading. Android is devoloped by Google , so google provide core libraries. It is a java oriented platform for devoloping and excecuting mobile applications. We can write programs in java and utilise android classes and API's. Applications and libraries mainly concentrated in mobile devices. Android applications can excecute in mobile device  with Android platform.   ipod  TabletPC  PDA  Embedded System ( Dedicated special purpose System) In embedded field lot of limitations for Android devolopment. Direct access to H/W is difficult in application level. We have to write driver programs for accessing H/W ( GPIO-general purpose I/O). After modifiying the Source Code and including the driver , recompile the OS and create image.     For biginning the Android development the following packages are...

ARM11 (S3C 6410 samsung processor based) Development board with 4.3" LCD.- Tyni6410.      The board having good quality and lot of features. 256 RAM 256 NAND flash Audio IN,OUT Video out 3 sereal ports (TTL also) CMOS camera ,WiFi Interface 4 USB Host,1 slave 5v Power adapter also provided. It will support Linux,Android,Wince,Ubondu. All softwares and supporting datasheets provided. With the help of this board ,I started my Android Developments. I planed to impliment GPS/GSM application for Vehicle Tracking and Navigation. Already I compleated GPS/GSM interfacing with my ARM7(LPC2148 based). Gps datas getting from vehicle ( location ,speed ,direction ,etc.) send to Mobile by SMS via GSM network.Traking and Security side software done, But due to the lack of LCD screen in the ARM7 board I could not get map and other information in the vehicle.And Gprs Application also incompleat. I hope these and more features (a Smart phone or Tablet PC) can b...

Global Positioning System Started to develop GPS/GSM project I purchased one GPS unit and GSM/GPRS modem for this project. ARM7 (LPC2148) processor (Blue Board) board is using for this project. GPS data receiving side is ok, position data is getting in NMEA  format(ascii text). In the first stage , I use this data for  maping in Google earth. GPS receiver data out is in UART (TTL3.3v) communication. Data received from GPS via UART conected to ARM through UART0. Processed data fed to the PC via BlueBoard's UART1. But my laptop having only USB. This problem solved by RS232 to USB convertor. GPS data to be linked to the Google Earth by any bridge software (earthbridge). Now the position showing in google earth according to gps data. In google Earth we can save the track,map,trip etc in XML formal and can be share with others by email. National Marine Electronics Association NMEA  has developed a specification that defines the interface between various pieces...
