Questions about MCU breadboards

It is possible to detect simple circuits from complex circuit diagrams. For example, single-chip microcomputer, crystal oscillator circuit, power supply circuit, and LED can be connected to single-chip microcomputer to form a minimum system;

1. Development board: It is a board that has been done by others in the peripheral circuit and can achieve limited functions, and you can program it to achieve its predetermined function. There are certain restrictions and it is not recommended. Self-study sheets are available.

Microcontrollers, build their own peripheral circuits, and get what functions you want to achieve, you must learn more than directly using other people's development boards.

2. Single-chip microcomputer: each pin function is fixed, you can write your own program according to his data to burn in, build peripheral circuits, and achieve certain functions, each company's single-chip microcomputer is slightly different, beginners are recommended to choose ATMEL's AT89S52, cheap, a 5 or so pieces;

3. Experiment board: I don't know if you are talking about the experiment box, which is more advanced than the development board, has more functions, and the module is clear, that is, the volume is larger, and it is generally used in schools when doing experiments.

As shown in Fig. The MCU development board integrates the functional areas of multiple experiments, which can make different experiments or complete different tasks. But they all share the same power supply, but some functional areas need to be connected to a short-circuit cap to input the signal output of the microcontroller into that functional area.

Basically, the functions to be implemented are fixed, that is, you said that only those who have them on the development board are talented, but the extended functions are not excluded. If you want to write a program to the single-chip microcomputer, first of all, of course, write a C or assembler on Keil or related software, and then compile it into a machine code that the single-chip microcomputer can recognize through the compiler, and then go to the single-chip microcomputer through the serial port line or other communication lines. The programming process of different types of single-chip microcomputers is also different from the ** line.

For details, you can check the microcontroller you are using. By writing and flashing the program into the microcontroller, you can verify the correctness of the experiment or achieve the function you want.

This is still very necessary, the meaning of the development board is not the role of the development board itself, the main value and significance is the data and technical support, if you encounter problems, someone will give you guidance, you can communicate with your classmates.

When I was studying at that time, I followed the tutorial of Wu Jianying's development board, and there were many classmates who communicated and made things together, and in such an atmosphere, I would learn and progress quickly.

This is the biggest significance of the development board.

The role of this board is summarized as follows:It provides stable and reliable circuit boards and devices, reducing hardware design and debugging cycles.

Schematics are provided to provide a reference for future re-plates.

Provide a source**, provide a reference for learning and research, and reduce the energy of learning from scratch.

Provide technical support and reduce the time to solve problems encountered in learningFor new engineers, the development board is very useful, and various resources are also very helpful.

The experimental board is very cheap, only 40 78, and you must have an experimental board to learn a microcontroller, and there are at least 20 exercises.

It must be necessary, and the microcontroller must be experimented with by himself.
