2、own in Figure 1. The remote control is used to generate the remote encoder pulse drive infrared emission control output of the infrared remote control signal, the remote control receiver on the remote control signal amplification, detection, shaping, demodulation remote encoder pulse. The remote con
3、trol encoder pulse is a serial binary code for the infrared remote control system, the serial code input to the microcontroller, its internal CPU instruction decode on the remote control, and perform remote control functions. Using the remote control as the input of the control system, we need to ad
4、dress the following key questions: how to receive the infrared remote control signal; how to identify the infrared remote control signal, and decoding software design, design of control procedures.SCM historySCM was born in 1971, has gone through three major phases of the SCM, the MCU SoC.It consist
5、s of computing device, controller, memory, input output devices.Its full name is a single-chip microcomputer, is typical of embedded micro- controller Microcontroller Unit, the commonly used letters of the abbreviation MCU single-chip, and it was first used in the field of industrial control.Master
6、microcontroller technology to enable more people in the industry, students,enthusiasts, product developers, the question arose due to the extensive application of SCM in the field of industrial control, microcontroller development board, the more famous such as e-DZR-01A microcontroller development
7、board.Microcontroller chip dedicated processor developed from the CPU.The first design concept by a large number of peripherals and CPU integrated in a single chip, the computer system is smaller, more easily integrated into complex and require strict control equipment on the volume.Single-chip, als
8、o known as single-chip microcontroller, it is not the completion of a logical function of the chip, but a computer system integrated ontoone chip.Equivalent to a mini-computer and computer, microcontroller only the lack of I / O devices.SCM rely on the program is running, and can be modified.Differe
9、nt可编辑资料 - - - 欢迎下载精品名师归纳总结functions through different programs, especially the special unique function, which is the other devices require much effort to do, while others make great efforts it is difficult to do.A not very complex functions using pure hardware to get the words of the 1950s developed
10、 74 series, or 60 during the CD4000 series, the circuit must be a big PCB board.If successful on the market in the United States in the 1970s series of microcontrollers, the result will be different.Just because a program written by the MCU through you can achieve high intelligence, high efficiency
11、and high reliability.Microcontroller for cost sensitive, so accounting for the dominance of the software or the lowest level assembly language, which is the lowest level than binary machine code language, since such low-level why use it.A lot of high-level language has reached a level of visual prog
12、ramming, why not.The reason is simple, is the microcontroller does not have a home computer as the CPU, also not as hard as mass storage devices.A visual high-level language to write small programs inside even if there is only one button, will reach tens of K of size.Nothing in terms of home PCs har
13、d drive, but for SCM in terms of is not acceptable.SCM in the utilization of hardware resources must be high, so the compilation of the original while still inheavy use.The same reason, if the computer giants operating system and application software to get home PC run up to the home PC can not affo
14、rd.It can be said that the twentieth century across the three power era of theelectrical era, the electronic age and has now entered the computer age.However, such a computer, usually refers to a personal computer, or PC.It is by the host, keyboard, monitor, and so on.Another type of computer, not h
15、ow most people are familiar with.This computer is smart to give a variety of mechanical microcontroller alsoknown as micro-controller.The name suggests, the smallest of this computer systemusing only one IC to make a simple calculation and control.Because of its small, usually hidden in a controlled
16、 mechanical stomach.Throughout the device, it plays like the role of the human mind, it is wrong, the entire device was paralyzed.Now, this single chip field of use has a very wide, such as smart meters, real-time industrial control, communications equipment, navigation systems, home appliances and
17、so on.A variety of products using the SCM, you can play the effect of product upgrades, often preceded by an adjective in front of the product name - smart, such as smart可编辑资料 - - - 欢迎下载精品名师归纳总结washing machines.Some factories or other amateur electronics developers to engage in out of certain produc

19、ontroller trail.Navigation device of the missile, aircraft, various instrument control, computer network communications and data transmission, industrial automation and process real-time control and data processing, widely used smart card IC, civil luxury car security system, VCR,cameras, the contro
20、l of automatic washing machines, and program-controlled toys, electronic pets, etc., which are inseparable from the microcontroller.Not to mention the field of automatic control, robotics, intelligent instruments, medical equipment.Therefore, the learning, development and application of the SCM will
21、 create a number of computer applications and intelligent control of the scientists, engineers.The microcontroller is widely used in the field of instrumentation, home appliances, medical equipment, aerospace, equipment for the intelligent management and process control, generally can be divided int
22、o the following categories:1. On smart instrumentationThe microcontroller has a small size, low power consumption, and control functions, and expansion of the advantages of flexibility, miniaturization and easy to use, widely used in instrumentation, combined with different types of sensors can be r
23、ealized such as voltage, power, frequency, humidity, temperature,flow, speed, thickness, angle, length, hardness, elements, pressure and other physical measurement.SCM makes the digital instrumentation, intelligent, miniaturization and more powerful function than the use of electronic or digital cir
