GPS/GSM Based Project

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 AssociationNMEA has developed a specification that defines the interface between various pieces of marine electronic equipment. The standard permits marine electronics to send information to computers and to other marine equipment

BEAGLE BONE BLACK FOR EMBEDDED APPLICATION

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

Smart TV or Internet TV

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
