PIC MICROCONTROLLER BASED DATA ACQUISITION SYSTEM

Abstract

Microcontrollers are a new concept of integrated circuits based on a multifunctional architecture. The majority of microprocessors require a lot of discrete components and ICs to execute a relative simple function, resulting in large and complex hardware. This is based on a fact that the microprocessors must be flexible, in the application point of view. This architecture is difficult to update and requires a lot of electronics knowledge and low level programming. Incorporating some basic functions inside of a microcontroller, the hardware can be quite simple and with low cost as well. Some of these basic functions are: A/D converter, comparator, PWM, serial communication, internal clock, RAM/EPROM memory, flash memory and programmable I/O. Some microcontrollers incorporates all of these functions in a single chip, the additional discrete components are minimal. Another advantage of the recent microcontroller is the programming process and the language used. The software can be made ...
