PIC microcontroller

PIC is a family of Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1640 originally developed by General Instrument‘s Microelectronics Division. The name PIC initially referred to “Programmable Interface Controller”, but shortly thereafter was renamed “Programmable Intelligent Computer.”
PICs are popular with developers and hobbyists alike due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, and serial programming (and re-programming with flash memory) capability.

What is an Embedded System?

Embedded Systems are those systems in which a Chip is programmed to perform a certain function. This Chip programming/burning can be done using several languages. These Languages may be C, Assembly, VB, Java etc. but for burning into the Chip mostly micro-controllers, these programs written in High Level Languages (HLL) are to be converted to Hex Code.

8051 is the basic Micro-controller used. Rest all micro-controllers are based upon 8051.

An embedded system is some combination of computer hardware and software, either fixed in capability or programmable, that is specifically designed for a particular kind of application device. Industrial machines, automobiles, medical equipment, cameras, household appliances, airplanes, vending machines, and toys (as well as the more obvious cellular phone and PDA) are among the myriad possible hosts of an embedded system. Embedded systems that are programmable are provided with a programming interface, and embedded systems programming is a specialized occupation.

Embedded Systems has applications in Robotics, Industrial Automation and various latest electronic appliances etc.

Interfacing the micro-controller is very important in Embedded Systems.
