Abstract:With the rapid development of computer technology, Single Chip Microcomputer are used more and more widely. MCU has become the electronic computer information engineering and other professional must study knowledge .This article is about the Proteus microcontroller based on knowledge learning system design and realization .The system is in the Proteus design coding input system ,output system ,interrupt ,timer/counter ,the serial communication function module .In detail,it’s implemented by Proteus simulation software and Keil software compiler . The design and implementation of the hardware of the system module is based on Proteus simulation software. The Keil compiler code realization of software modules.Finally through the Proteus and Keil realize the function of each module. In order to meet in the classroom teaching of MCU theory knowledge,through the demonstration of the system corresponding to the module,the system is designed to study the knowledge vividly.
