Bachelor of Electronics, I ve been working for 2 years, is it necessary to buy a 51 single chip micr

1.Beijing Zhongguancun"Zhichun Building"with"Zhongfa Building"There are many electronic components.

Go around a lot, definitely long experience.

2.There are several categories of single-chip microcomputers, such as 51 series, RISC series, ARM, etc., and it is recommended to start with 51 series, for example, ATMEL's AT89C51 single-chip microcomputer is the most suitable for entry.

3.Buy a study board to get started quickly and get twice the result with half the effort. Check this out.

4.Electronic technology is a very practical subject, and it is recommended to be more hands-on.

5.I have been doing hardware circuit development for 7 years, and I can help you if you have any questions.

Give more points, a simple program can help you write!

If you are not busy with work, it is necessary to not only do experiments, but also do private work, hehe

Industrial control specialty stores should have sold.

There is no need! It's better to make one yourself! If you plan to develop in this direction, you should do it!

There are indeed many kinds of microcontrollers. So if you're talking about the kind of chip-based microcontroller, such as ARM, FPGA, C51 or something. After you understand the principle, each microcontroller is only different in programming language and function.

My suggestion is:

1. If you have a teacher or senior to teach you the circuit by hand, (note, it is not simply a class to teach things in books, but practical help.) Or if you have learned some single-chip microcomputers before, then you must go to the electronics market to buy components, make your own development board, and use C51 chips. Because C51 is the C language in the single-chip microcomputer, there are many theories, and in fact, this kind of chip is basically not used.

In between, you can exercise a lot of things, such as bargaining for buying and selling components, soldering techniques, circuit inspection and troubleshooting. Don't think it's time-consuming, these things will be useful in your work in the future.

2. If you don't have any MCU foundation, no one will help. Then just go to the nearby electronics market or buy a cheap C51 microcontroller online. This method has the effect of paying for a teacher yourself.

After doing all the programs in the attached materials and implementing some simple functions by yourself, you still have to go back to the first step. After all, no matter how you learn other people's MCUs, you still have to be able to make one yourself in the end to be qualified. So don't buy an expensive microcontroller, it's just a thing that is discarded when you run out.

After understanding the principle, you can choose different chip microcontrollers according to your different development directions to continue learning. ARM is suitable for integrated processing, FPGAs are suitable for signal processing, and Microchip's chips are suitable for industrial control and automotive electronics. Maxim's chips are suitable for energy management.

Buy a cheaper, with a little more of the process can be, don't want to be proficient quickly, that's absolutely impossible, give up the idea of learning quickly as soon as possible, otherwise buy any development board for nothing, remember: learning single-chip microcomputer must not be impetuous, everything is actually the case.

TX-1C recommended by Mr. Guo Tianxiang, the functions are very complete, if you are a beginner, it is enough, and the supporting tutorials are relatively complete, and it is more convenient to find.

This is not specifically about which is better, the specific sock type volt refers to Wu Jianying single-chip microcomputer development board.

1. Overview of SCM and embedded system: including the concept of embedded system, the characteristics of MCU, application fields and development trends, the performance comparison and selection of mainstream MCUs in the market, the introduction of commonly used 51-core MCUs, the development methods and processes of general embedded systems in the industry, the introduction and use of development boards and related development tools, etc.;

2. The use of 51 single-chip microcomputer architecture and basic resources: including the introduction of the working principle of single-chip microcomputer, the introduction of 51 single-chip microcomputer architecture, the introduction of the minimum system of single-chip microcomputer, and the proficient use of 51 basic resources of single-chip microcomputer such as parallel port, interrupt, clock and reset, serial port, etc.;

3. Basic resource expansion design of single-chip microcomputer: including memory expansion design, programmable and non-programmable IO interface expansion design, I2C bus simulation design, etc.;

Fourth, the design of input and output equipment: including independent keys and matrix keyboard input methods, digital tube and liquid crystal display interface design, buzzer design rent;

7. Introduction to the development environment and development tools: the use and soft debugging of the Keil uVision2 integrated development environment, etc.;

8. Software and hardware system integration and debugging methods, and technical documentation writing specifications.

It would be better to say clearly what development board, 51 or arm7, arm9

SCM is widely used in the fields of instrumentation, household appliances, medical equipment, aerospace, intelligent management and process control of special equipment, which can be roughly divided into the following categories:

1.Application on smart instrumentation.

MCU has the advantages of small size, low power consumption, strong control function, flexible expansion, miniaturization and easy use, etc., and is widely used in instrumentation, combined with different types of sensors, it can realize the measurement of physical quantities such as voltage, power, frequency, humidity, temperature, flow, speed, thickness, angle, length, hardness, element, pressure and so on. The use of single-chip microcomputer control makes the instrument digital, intelligent, miniaturized, and the function is more powerful than the use of electronic or digital circuits. For example, sophisticated measuring devices (power meters, oscilloscopes, various analyzers).

2.Application in industrial control.

With single-chip microcomputer, various forms of control systems and data acquisition systems can be formed. For example, the intelligent management of the factory assembly line, the intelligent control of the elevator, various alarm systems, and the computer network to form a secondary control system.

3.Applications in household appliances.

4.Applications in the field of computer networks and communications.

Modern single-chip microcomputer generally has a communication interface, can be very convenient with the computer data communication, provides excellent material conditions for the application between computer networks and communication equipment, and now the communication equipment basically realizes the intelligent control of single-chip microcomputer, from mobile phones, first-class machines, small program-controlled switches, building automatic communication call systems, train wireless communication, and then to the daily work of the mobile **, cluster mobile communication, radio walkie-talkie, etc.

5.The application of single-chip microcomputer in the field of medical equipment.

MCUs are also widely used in medical equipment, such as medical ventilators, various analyzers, monitors, ultrasound diagnostic equipment and hospital bed call systems.

In addition, single-chip microcomputers have a wide range of uses in the fields of industry and commerce, finance, scientific research, education, national defense and aerospace.

Can you tell us more about what kind of needs? The choice of development version is based on needs. Because the general development version features are fixed.

If you are purely learning, you can try to use software simulation (Proteus + Keil), Proteus can build the circuit you want by yourself, and then use Keil to write the program**.
