The role of the MCU LY 51S for universities

It is the last word to make an open board by yourself, from the most basic transistor amplification circuit (for example, the dynamic drive of a single-chip microcomputer requires a triode amplification circuit), to the smallest system of a single-chip microcomputer.

In this way, you can improve your hands-on ability.

The microcontroller book goes from hardware to software chm

Learning single-chip microcomputer does not rely on having a good development board, like our student family to make a slightly cheaper one, and when you play through, you find that the development board is actually a platform for us to learn to verify. I also participated in the 2011 national competition, and I deeply understand that this line of work requires our perseverance. Congratulations in advance, huh

If a product is still selling well after a few years, the quality is trustworthy. This is the same as when we buy a car, and we want to hear feedback from everyone. But there is still no perfect car.

ly single-chip microcomputer is very rubbish, the failure rate is very high, can only be used for teaching, demonstration instruments, can not be used for commercial and industrial supplies, it is a lie to say that it is ugly.

To learn a single-chip microcomputer, you don't have to buy an experimental box, you can also get a development board, and you can do it yourself. Check out my blog, the least solder joint method might help you a bit.

It is very likely that the P0 port is not connected to the pull-up resistor. There is no problem with the software. The pull-up resistor connection method will give you a diagram. Resistance takes.

You can connect external buttons, preferably with matrix keyboard, which can save the IO port.

As long as there is an idle IO port that is drawn out, just connect it.

This board is rubbish.

Is it Freescale's? I guess that's what you want, so I'll send it to you first.

The email has been sent, please check.

Brother, I'm in the same situation as you, do you still have CD-ROM materials?

**Buy? If it's online, you can call the seller to pass it on to you.

<> thanks to those who have been able to take a slurry of acres.

Don't they all use Wu Jianying single-chip microcomputer development board now?

Regardless of whether you have installed the driver or not, it should be a responsive "unrecognized device" after plugging in, in this case, your ** line is not the original configuration, try to change the root, try to change the computer, and then it is a matter of the board.

Hello! The development board does not need you to connect, just write the program according to the schematic.

At present, learning computer science is still very good and good employment, computer is divided into many majors such as graphic design, UI design, Internet marketing, e-sports, animation, are very good employment majors, choose your favorite major.

1. Electronic information engineering, communication engineering, automation, measurement and control technology and instruments and other majors are closely related to single-chip microcomputer.

2. If you simply like single-chip microcomputer, the above majors are suitable for applying.

Hello, since you are interested in single-chip microcomputer, you may wish to choose communication engineering for the major of the university, I am out of this major, if you want to learn single-chip microcomputer, it is recommended that you learn the following courses, C language (very important, the basis of programming), digital electricity and analog electricity (also very important, the basis of designing circuit boards), and then what what embedded programming, single-chip microcomputer Bunsen courses, such as 89C51, STM32 and so on! The most important thing to learn single-chip microcomputer is hands-on, if there is no actual condition, it is recommended to install protues and keil two software, you can simulate a lot of single-chip microcomputer systems! I hope it can help you, I hope to adopt, thank you, if you don't know anything, you can ask!

Electrical, Automation or Computer Science.
