Which single chip microcomputer is better for novices to choose for learning single chip microcomput

Just learn 51 first, the absolute entry-level, you can choose Guo Tianxiang's for the development board, it's been many years, the information is very complete, and then you can look at 32 or something.

Circuit Principle, Modular Electricity, Digital Electricity, Communication Principle, MCU, Protell99, High Frequency Electronic Circuit, Signal System, Digital Signal Processing, FPGA, DSP, etc.

I think: circuit principle, modular electricity, digital electricity, single-chip microcomputer, is to learn well.

The signaling system depends on what direction you are going to go In the direction of communication, it is much more demanding. If you just play with a microcontroller, the requirements are not so high, but you must always know the basic transformations, the industrial PID controller, these are all designed and calculated by yourself, of course, you can use MATLAB

Secondly, the principle of communication, I think that modern microcontroller technology should no longer be the era of a single microcontroller working alone, it should be a batch of microcontrollers and working together with PCs, so encoding and error control are all inevitable problems

ARM is actually a single-chip microcomputer, but it is more resourceful and works at a frequency of more than 300MHz

For beginners, of course, it is better to choose 51 microcontroller as a beginner, and we should pay more attention to the cultivation of programming thinking and strengthen the rational use of limited resources

This kind of thinking is feasible on any device, so it's advisable to start simple

1. **Be low.

Because it is a student, there must not be much economic foundation, it is necessary to choose a low-level single-chip microcomputer, and the one-chip microcomputer that is too expensive to learn at the beginning has too many functions, and beginners can not master it well, and the low-level single-chip microcomputer has fewer functions and is easier to master.

2. Maximize peripherals.

If you buy a learning board, then it is best to choose a learning board with more peripherals, because it will be more expensive to buy peripherals alone, and the degree of integration is not high, it is best to directly choose a learning board with more peripherals, so that you can learn all the module functions at one time, of course, ** will grow, as long as it is controlled within 200 yuan.

3. The operation is as simple as possible.

If the development board is broken, whether it can be returned or replaced, etc., if you have the above points, then you can start.

There are many varieties of single-chip microcomputers, and the following are more commonly used.

MCU, MCU.

Series 0TP single-chip microcomputer.

In the face of a large number of single-chip microcomputers, the performance requirements of single-chip microcomputers and the developability of single-chip microcomputers are usually considered when selecting models.

2. Combine the low 4 digits of 21 hours as the high 4 digits and the low 4 digits of 22 hours into a new data, and the results are stored in 20 hours

3. Convert the 8-bit hexadecimal data in ACC into decimal data, the hundred digits are stored in 21h, and the ten digits and single digits are stored in BCD code for 20h

I won't specify which one is better, there is a suspicion of advertising, and it will be deleted by the system or administrator.

Fields of application. 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:

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.

It can be said that today's household appliances are basically controlled by single-chip microcomputer, from rice cooker, washing machine, refrigerator, air conditioner, color TV, other audio equipment, and then to electronic weighing equipment, all kinds of ubiquitous.

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.

At the beginning of the comic Luxue, it generally starts with 51 single-chip microcomputer, and then changes to a more advanced single-chip microcomputer after playing almost the same.

The operation of 51 is relatively simple, relatively typical, the price refers to the cheapness of Qige, and the most important thing is that there is a very, very large amount of information on the belt.
