DOT MATRIX LED DISPLAY5 x 7 LEDs per characterLong lastingHighly effectiveLow power consumptionHigh luminanceRobustnessViewing angle 160 degreesLow price

Software Profile

Keil Development tool

• Keil software provides the ease of writing the code

in either C or ASSEMBLY.

• Keil Software combines Project management,

Source Code Editing and Program Debugging in

one powerful environment.

• It acts as a CROSS-COMPILER.

Contd..

Flash Magic

Flash microcontroller can be erased and re-

written as many times as possible.

Flexibility to reprogram number of times and

its low cost make it ideal for use in a wide

areas of applications.

This product is a combination of intelligent

hardware and software.

LPC FLASH UTILITY TOOL

The flash utility tool is used to burn the code

into the ARM processor

DB socket female to GSM connection

Advantages Compact

Good resolution

With a wide 160 degree viewing

Easy to use, since it is SMS controlled

Time consumption is very less due to fast processing

Low cost implementation

Display can be controlled from any part of the world

FUTURE IMPLEMENTATION

• Multiple message display board can be conceived

• Number keys can be provided to update the phone

numbers of the authorized persons

• Even voice messages can be made to drive the

display board

• The display can be interfaced with the computer and

hard copy can be obtained

Conclusion

Coding has been made flexible.

With all the above features being implemented

conveniently and low price it is a promising

application most likely to replace the conventional

notice boards in various campuses.

Thus it would reduce the manual intervention seen in

conventional notice boards
