controller. The messages stored in the computer acts as a record for future reference.
Abstract – This project is designed using ARM-LPC2148 interfaced with Graphical Display. At present, when information has to be updated in a notice board, it has to be done manually. Also in present electronic systems, no matter how many displays are present, only a single notice can be sent to all of the notice boards irrespective of their places. In order to overcome this disadvantage, multiple displays along with a decoder are used to select a particular display and the corresponding information is sent through an ARM controller by using GSM technology. The entries can be documented and a record may be maintained for future use by using visual basic. The controller has internal a real time clock used for synchronization of data. A resistive touch screen is used to access the previous notices and also progress details. The monitoring system consists of an image sensor which captures the images for the specified amount of time and the images can be transferred through an USB port to a PC for storage purposes.
The monitoring system includes a micro-miniature camera which would be capable of acquiring 3 mega pixel color images, transfer them on to a personal computer through a Universal Serial Bus (USB) link, and also store the image in a micro SD card after applying an image compression algorithm. The report explains how a raw image data is captured by a CCD sensor and interfacing of the sensor with an ARM7 processor. II. COMPONENT DESCRIPTION
