INTRODUCTION An Embedded System is one that has computer-hardware with software embedded in it as one of its most important component. It is dedicated computer-based system for an applications or product. It may be either an independent system or a part of larger system. An Embedded System is a special-purpose computer system designed to perform one or a few dedicated functions.
CLASSIFICATION OF EMBEDDED SYSTEM Small Scale Embedded System Medium Scale Embedded System Sophisticated Embedded System
COMPONENTS OF EMBEDDED SYSTEM An Embedded System has following three main components: Hardware Application Software Real Time Operating System
HARDWARE OF EMBEDDED SYSTEM PROCESSOR MICROPROCESSOR MICROCONTROLLER OTHER HARDWARE UNIT POWER SUPPLY CLOCK OSCILLATOR CKT REAL TIME CLOCK AND TIMERS RESET CIRCUIT MEMORIES INPUT,OUTPUT AND I/O PORTS APPLICATION SOFTWARE RTOS
APPLICATIONS OF EMBEDDED SYSTEMS Audio like mp3 players Cellular telephones and telephone switches Engine controllers and antilock brake controllers for automobiles Home automation products, such as thermostats, air conditioners, sprinklers Handheld calculators DVD players and recorders Medical equipment Computer peripherals such as routers and printers
TEMPERATURE PROGRAMMER In many area’s of daily and technical life, making temperature measurements is the most important instrumentation task.”Intelegent”digital sensors, which can do more than just output temperature readings, are winning more ground as compliments to classical analogue techniques. An example of such a sensor is the Dallas Semiconductor DS1621. Naturally, the main job of a modern digital temperature sensor is to determine the current temperature. It does this by measuring its own temperature, which is nearly the same as the temperature of its surroundings, and converting this analogue temperature value into a digital word that it sends to a microcontroller via a serial interface.
ADVANTAGES Debugging: Embedded Debugging may be performed at different levels from simplest to most sophisticated depending on the facilities available. Reliability: Embedded systems often reside in machines that are expected to run continuously for years without errors and in some cases recover by themselves if an error occurs. Thus are reliable. Portability: Embedded System have greatly reduced the size of its’ various application. Thus it has become easy to handle. Economic: Recent technologies have reduced the prices to a great extent.
CONCLUSION Today in this fast moving world, everyone wants to handle small and portable products which are comfortable to them. Thus embedded systems are proving blessings for them. The growing needs of various applications such as home appliances, various hard wares, industrial needs etc have demanded development in this field. Satellite developments are also demanding the growth of embedded system. It has become part of our life in form of mobile phones, laptops and various other appliances. Temperature Programmer is project that employ embedded system. There are lots many projects based on embedded system and have some or other application and can be used in various products
