浅谈51单片机在红外遥控器系统中的应用_汪国坚（On the 51 single-chip infrared remote control system in the application of _ Wang Guojian） Abstract: This paper introduces the application of 51 single chip microcomputer in the infrared remote control system, analysis of the principle and design of 51 single-chip infrared remote control system, and the MCU hardware and software requirements, because the microcontroller technology is not very mature, the inevitable problems in application, the problems of brief analysis. Key words: 51 single chip microcomputer infrared remote controller application design constitution question 51 SCM is the current all intel8031 instruction system microcontroller collectively, but also by the intel8031 microcontroller development. The application of single chip microcomputer technology in infrared remote control system is an example of 51 SCM widely used in the field of industry. The design uses a single-chip microcomputer 51 remote control system, not only the hardware interface simple programming, and can be freely set diversification, but also environmental protection, applications are more extensive, greatly facilitate the needs of modern life, but also brought great economic benefits. Development and present situation of 151 single chip microcomputer Single chip microcomputer is the abbreviation of single-chip microcomputer, that is, in a chip integrated with the computers C, P, U, R, A, M, R, O, M, timing / counter, I / O interface and other circuits. SCM development is divided into three stages, the first stage is in 1976, Intel company launched the MCS-48 series It includes 8 bit microcontroller, C P U, 1K M, O bytes of R 64 bytes of RAM 27 I/O lines and 1 8 bit timer / counter, then the microcontroller memory capacity is small, the addressing range is small, no serial interface, instruction system function is not strong; the second stage is in 1980, Intel launched MCS-51 MCU, it has 8 bit CPU and 4K bytes of ROM 128 bytes RAM 4 8 bit parallel, 1 full
