0 Introduction There are many types and styles for the design and development of digital voltage meters. Traditional Digital Voltage meters have their own characteristics and are suitable for manual measurement at the site, however, to complete remote measurement and further process the measurement data, the traditional digital voltmeter cannot be used. Therefore, a digital voltmeter Based on PC communication is designed in this paper. This table can transfer measurement data and process measure

Single-chip microcomputer and (serial screen) touch screen communication based on Modbus Protocol (graphic)Introduction: Touch screen can be intuitive, vivid display of operating parameters and operating state, and through the touch screen screen can directly modify the system operating parameters, human-machine interaction is good. Touch screen and single-chip communication, the need for a single-

"abstract" in order to reduce the development difficulty of DSP system software, to ensure the real-time nature of the system, shorten the development cycle, the embedded real-time operating system Μc/os-ⅱ porting to the DSP chip is a common method at present. This paper introduces the characteristics of embedded real-time operating system (Μc/os-ⅱ), and analyzes the porting method of Μc/os-ⅱ operating system in the current popular DSP

This article is original by purplesword (jzj1993). For more information, see. Original web site http://blog.csdn.net/jzj1993 We have introduced several solutions for preparing the experiment board. Here we will first introduce solution 1. I will build a simple single-chip microcomputer lab Board together with you to enjoy hands-on practice. We have two ways to build our own lab board. One is to use a bread board, and the other is to use a universal we

Single-chip microcomputer minimum system, or the smallest application system, refers to the system which is composed of the least component and the microcontroller can work. for the 51 series microcontroller, the minimum system should generally include: single-chip microcomputer, crystal oscillator circuit, reset circuit. a minimum system circuit diagram for a 51 microcontroller is given below. Descripti

When the user encountered a U disk failure will usually use U disk production to repair, but in the U disk volume production operation must master U disk main control chip model before the next operation, then how can you know the main control chip model of U disk? Let's see what the easiest way for us to share is the master. 1, first, plug the need to test the U disk, and then run the

How to interconnect single-chip serial communication rxd with txd Category:8051 2012-04-0711: 35 Read by 348 Comment (0) Favorites Report Reprinted from: http://blog.csdn.net/sdwuyulunbi/article/details/6632382 I believe many people are confused about how to connect rxd and txd when the microcontroller communicates with a computer or chip. In some circuit diagrams, some are

After the chip sample stream comes back, all people are most concerned about whether the new functions are normal and whether the problems found in the old version are solved, this requires replacing the old chip in the verification system and re-running the system for verification. In the sample phase, various strange problems may occur due to the poor encapsulation and low yield rate. The

The 40 pins of a microcontroller can be divided into 4 categories: power , clock , control , and I/O pins .1. Power supply:⑴VCC-Chip power supply, connect to the + +;⑵vss-ground end;2. Clock:XTAL1, XTAL2-crystal oscillator circuit inverting input and output terminals. 3. Control lines: control lines Total 4, ⑴ale/prog: Address latch allow/on-chip EPROM programming pulse ①ale function: Used

No external cables or connectors and hot plug-n-play is sup

Advantages and disadvantages of embedding an operating system in a Single Chip Microcomputer As early as 1960s, some people began to study and develop embedded operating systems. However, it has not been mentioned more recently in China. The increasing importance of it in areas requiring real-time processing, such as communication, electronics, and automation attracts more and more attention. However, people often talk about some famous commercial

The debugging of the algorithm porting encryption chip contains 2 parts: Communication Debugging and Algorithm debugging. Before talking about the communication debugging skills, the next chapter will be the algorithm debugging problems in the analysis and summary, to help customers to complete the debugging smoothly.Frequently asked questions in algorithmic debugging:1. Do not build your own projectWhen porting the algorithm, the customer does not ne

Hello everyone, this is the use of a blog, this article is the ATSHA204A encryption chip configuration, mentioned above, atsha204a encryption chip internal ROM three areas, one is Config zone, one is slot zone, there is an OTP zone, This article not only explains Config zone configuration, but also explains the slot and OTP area configuration method, and unifies the official library to demonstrate the code.

Speaking of the 51 MCU clock first thought about 51 o'clock how to work. Micro-controller to work must have a "power", for 51 single-chip microcomputer, this "power" is the clock source. A 12MHz crystal oscillator is used as the clock source for general applications. Generally the first method is used more often. When the internal oscillation mode is selected, there are two small capacitors next to the crystal oscillator. These two capacitors are call

1-hour multi-thread structure application Generally, various control systems used by single-chip microcomputer have various interaction processes such as field data collection, control output, working status detection, and data transmission; the mismatch between the response speed of various peripherals and MCU is an important factor restricting the overall performance of the system. In the face of this interaction bottleneck, the use of time-based mu

My view of single chip microcomputerRecent health is not good, look back on such a few days to walk, now think, also to summarize the time. I have been in the field is very bad, a person, talking people do not have to work a person, sleep is a person. Very lonely. Of course it's a big part of the reason. I am a person who is eager to be loved, but a long time without. Now some of the professional Learning summary summary, in the future to see the youn

technology, including 70 NM evolution to 50 nm, and then evolve to 40 nm or 30 NM process technology, mobile phone customers will also have to redesign, but semiconductor products every 1 years of technology will be new, memory problems also drag on the speed of the introduction of mobile phones, So, like eMMC, the concept of wrapping all the memory and control chips that manage NAND flash on 1 MCP is becoming increasingly popular.eMMC design concept, is to simplify the use of memory in the pho

said ashamed, has always been, in school is also a lot of things, but instead of 51 single-chip computer This basic thing did not seriously to do, at the beginning of self-study 51 not one weeks, and then to Freescale 16 single-chip machine up, so that 51 has not thoroughly made a clear. is not as good as I know s12 monolithic computer what piece of RAM Ah, flash size Ah, instead is 51 not sure answer OH.

In fact, learning single-chip computer This kind of thing is not what single-chip computer learning Forum, first look at the information books, and then practice, if you encounter any problem can not solve the online search for information, on the network on the single-chip microcomputer frequently asked questions are very many, how to pick out the answer you nee
