MCU is a kind of microcomputer. At present, there are 8051, AVR, ARM7, ARM9 and other series. Among them, "8051" is derived from Intel's MCS-51 series chip, but currently different manufacturers mainly use compatible chips, such as Ateml's 89C51/89S51 system, Hongjing's STC89C52RC. This article is the macro crystal STC89C52RC, the chip is simple to burn, only through the macro crystal tool through the serial port MAXRS232 TX, RX pin can burn the program to the chip, is a very good embedded entry Basic, tutorial, 51 series of learning boards are generally using STC89C52RC chip, it can be seen that its versatility is very wide, then how can we quickly learn 8051 microcontroller.
Learning the CPU of the 51 series requires the memory pin function. When I was learning, I benefited from the simple memorizing method. The function and position of the foot are mastered very quickly. I can easily remember P0 and P1 without memorizing the hardback. P2, P3 pin, please see the picture below:
After learning the function of the pin, if you want to start the circuit of the MCU, you need to understand the peripheral connection, so that you can lay the foundation for the MCU control circuit. This is the must remember to learn 8051 system microcontroller, the following is the minimum circuit diagram of 51 single-chip microcomputer, as long as the following aspects are connected, you can simply power on the operation of the microcontroller, the application of the function pin is added on the basis of the minimum system. .
Learning MCU, you can't live without a paper tutorial, go to a local bookstore to pick or cheap, you can go to excellence, Dangdang. With the tutorial can better guide how to systematically learn the microcontroller, especially to learn the C language version, I used to study the example of "51 single-chip (C language version)" post and telecommunications press, it is good. That is, there is a theoretical basis of single-chip microcomputer, and there is C language learning. I have been in contact with C language for a long time. I used C++Builder to develop Windows. Through the tutorial, I found the C language of Windows and the C language on the single-chip computer. The difference lies in the definition of the pin, which is unique to the MCU C.
The tutorial has it, but how can you know how you have learned without knowledge? When you learn it once, practical application is another matter. Programming now 51 systems are using Keil v3, it is best to put on the "filter 0xfd character bug" correction program, I have tried to experience the experience of this character is not correct and wasted time, patching can reduce The strange phenomenon we encountered in debugging the program.
Using Keil software programming can only detect the correctness of the C language programming grammar, but can not verify that the real function is realized. Now you can use the single-chip software simulation Proteus (tutorial) to simulate and debug the board and program functions. However, although the simulation is a good method, it is not as good as using the single-chip experimental board, the program written by Keil, and then writing the program to the single-chip microcomputer through RS232 for substantive operation, in order to better understand the performance and hardware of the single-chip microcomputer. The use of the pieces, do not buy the smallest system, this is only for the people who have mastered the control of the MCU, they have their own peripheral circuit board, only need to connect the corresponding MCU to drive the circuit according to their actual situation. It is not suitable for beginners. It is better to get started with the MCU experiment board. The more functional, the more content you learn, the more familiar you are with the application of the MCU. The following is a single-chip learning board, on Taobao, the price is below 200 yuan, there are video tutorials, more suitable for beginners, interested users can refer to, choose a good learning board, counseling, communication is fast Learn how to use a microcontroller.
Learning a skill, the most valuable is perseverance, continuous learning and summary, will improve. Learning 51 series of single-chip microcomputer is a stepping stone to enter the embedded field. If you are electronic, you can also consider starting from the simple 51 and moving toward more advanced applications.
