Working process
Single chip microcomputer automatic completion of task to give it the process, is also the microcontroller program execution process, i.e. a executed instructions of the process, the so-called is the single chip microcomputer instruction execution of all kinds of operation requirements with the form of the command to write down, this is the design personnel give it the instructions of the system of the decision, an instruction corresponds to a fundamental operation; Single chip can perform all of the instructions, is the single chip microcomputer instruction system, and different kinds of single chip microcomputer, the instruction system is also different. In order to make SCM can automatically accomplish a specific task, must take to solve the problem into a ries of instructions (the instructions must be lected single chip can identify and executed instructions), this ries of t of instructions will become program, the program need to be stored in the memory function is part--storage. Memory by many storage unit (minimum storage unit) composition, like big buildings have many of the same room, the instruction is stored in the unit, the unit of instructions in take out and execute like big buildings of each room i
s assigned to the only one room number, each a storage unit must also be assigned to the only address number, this address, known as the address of a storage location, such as long as know the address of the storage unit, you can find the storage unit, including storage instructions can be taken out, and then executed. Program is usually quential order, so the instructions in the program is also a quence of storage, microcomputer in the execution procedures can put the instructions to take out and to perform a, there must be a component can track instructions location, the components that are the program counter PC (including the CPU) at the beginning of the execution procedures, to PC attached to the first instruction program in the address, and then get each to perform commands, PC in content will automatically increa, by the instructions to increa the length, may be 1, 2 or 3, the next instruction to point to the starting address of the, ensure instruction quence execution.

The application of single chip microcomputer
At prent single chip microcomputer permeate every aspect of our lives, almost hard to f
ind no trace of the single chip microcomputer which field. Missile navigation device, the plane on various kinds of instrument control, computer network communication and data transmission, industrial automation process real-time control and data processing, the extensive u of all kinds of intelligent IC card, civilian luxury car curity system, video, video camera, automatic washing machine control, and SPC toys, electronic pets, all of the cannot leave the microcontroller. Not to mention the automatic control in the field of intelligent instruments, robot, medical equipment and various kinds of intelligent machinery. Therefore, the study of single chip, the development, and the application will create a number of computer application, and intelligent control of scientists and engineers.狗狗与我的十个约定
Microcontroller learning
Single chip technology have been widely ud in every field, this is a very popular in the unceasing innovation and technology. Have a chance or are interested in studying the door technology, is to be encouraged to try, this technology is also recommended door. In
fact many people now u the C programming language, asmbly ems to be behind The Times, however, it is still the most direct description language, hope some experience of the author, a little reference for beginners. Learn the key of single chip microcomputer, also is to study the programming, learning to make up ChengXian learning instruction system. Master the accurate meaning, using the instructions and related conditions and hardware resources, the relations of the Understand the hardware resources, such as memory, interruption, counter, timers and I/O, and external resources. A program or a program, always a certain purpo or some purpo, organization instructions, with the language to mobilize the related resources, achieve certain design goal. Learning programming the primary phas, can be read from a small routine started by Jane to numerous, 2, and gradually to read a short complete program. Like before writing articles, should have to learn to read the article, article describing, finally can write a good article. Reference existing procedures for a new purpo modify the program; Gradually skilled can strategy resource architecture program. Read program will analyze the program. Program and the article, there in a program should have a clear purpo, an
alysis program to have the concept of paragraphs and architecture. No matter how long the program, it will be divided into veral paragraphs, simplified structure diagram, the program's structure and purpo is clearly visible. Read procedure, can e the thread of the program, understand the gist of program, if we can find out the sword of incision, still can find and modify the omissions, is from a programming staff not far away. Write a program, often in one take, then don't pay attention to add comments, actually comments is very important. Becau a commercial value software, often can be yourlf or other personnel within the team repeatedly borrow, again and again modification; Clear comments, favorable future borrowing and modification. Note the key is: the memory unit assign the u, marks definition, procedure of inlet and outlet, I/O u. The all should have a clear list, not in u and modify conflicts, also conducive to testing software failure. For a long program, had better have paragraph the labeling of target. A programming staff of resources and the relationship between language, should have a profound understanding. Resources are the object of the language is to be described; Programming is organic to organize language, u and transfer the resources, and the
n reach some design purpo. Using relevant instructions composition statements, and describe the changing process of some resources, which constitute a events; Interlaced veral events constitute a design project. The timer and counter that events have the time and the concept of order, also is our common speak of time and space concept. SCM (computer as well) to describe the space and time, also can describe our concern many events; Therefore, we also are all over the side of the single chip computer. On the phone, mp3, PDA, the home of air conditioning, the refrigerator, microwave oven, and vehicle, the office of printers, fax machines, all areas of measurement control instruments and so on, microcontroller is everywhere. Really master of single chip microcomputer, no doubt, to the personal employment and career development is very beneficial. A truly effective master this door technology, but also to the related electronic technology is certain to fix for, such as digital logic and analog electronic technology and electronic technology foundation. The ri the electronic technology in addition to the single chip microcomputer, and CPLD, FPGA, DSP technology. In the prent application ries microcontroller ARM and most widely ud. Hope are interested in the opportunity and fri
ends, according to their own conditions and work need, first introduction to master the esntials, we learn the practice, always began in earnest.四支僵劲不能动
