Embedded ordering module, find an embedded ordering system design aspects in English and translation

A classmate of mine now went to the Oriental Saifu to participate in embedded training and learning, it is said that the reputation in Beijing is the best, and the students are very responsible, he chose the ** monitoring system project based on arm+linux, it is recommended that you check it yourself to ask; Here are the steps he gave me to learn the embedded method: 1. Basic knowledge:

Objective: To understand the working principle of hardware, but with an emphasis on embedded software, subjects: digital circuits, computer composition principles, embedded microprocessor structure.

Assembly language, C++ compilation principles, discrete mathematics. Data structures and algorithms, operating systems, software engineering, networks, databases.

Method: Although there are many subjects, they are all relatively simple foundations, and most of them have been mastered. It may not be a full course, but it can be taken as needed.

Main books: The C programming language (I haven't had time to read it), Data Structures-C2.

2. Learn Linux:

Objective: To have a deep understanding of the Linux system.

Method: Linux - Linux system programming development - driver development and analysis of Linux kernel. Let's look at the depth first, then the main principle.

After reading it a few times, look at the scenario analysis, compare and look deeply, the two books are crossed, the depth is the outline, and the love is the goal. The anatomy is the version, which is suitable for learning. Finally go deeper**.

Main books: Complete Anatomy of the Linux Kernel, Advanced Programming in the UNIX Environment, In-depth Understanding of the Linux Kernel, Scenario Analysis and Source Generation.

3. Learn embedded linux:

Objective: To grasp the embedded processor and its system.

Methods: (1) Embedded microprocessor structure and application: direct ARM principle and assembly can be done, do not repeat x86.

2) Embedded operating system: UCOS II is simple, open-source, and available for getting started. Then delve into uclinux.

3) There must be a development board (arm9 or above), and you can participate in training if you have the conditions (make fast progress and be familiar with some friends). Main books: Mao Decao's "Embedded Systems" and other ARM9 manuals and ARM assembly instructions, etc.

First of all, your ARM development board should be ported with QT file system, or then install QT, and then configure some environments, and then use the cross compiler to compile on PC, after compiling it, it can be ported to ARM through any method of network, serial port or USB flash drive, of course, there will be many problems encountered in this process, which need to be solved step by step, just take your time, I am also grinding it step by step, you can take a look at my blog, which writes about my learning Qt and its porting process.

If you don't understand, you can consult again.

Hope it helps.

I recommend this book to you.,The complete manual of embedded linux application development that I read when I was in college.,Wei ++ wrote.,The content of the transplant is talked about above.,Personally, I think it's good.,Non-advertising.。 If you buy a development board, there is an instruction CD on the board, and there are many examples of how to use it. Specifically, the development board is connected with a network cable and a serial port cable, and it is carried out under Linux.

Classmates, you should use it for your graduation project. I'm so lazy, I'll show you a way. You go online and find a document on the design of an embedded ordering system.

Then copy and paste it into Google Translate to paste the translation out. Modify the formatting. That's it.

Definitely passed. That's what I did four years ago. There is also this translated thing that the school does not look at at all.

Just fool around and don't take it too seriously. Plus, it's your own business, don't be too lazy. With a snack, it can be done in half an hour at most.

I wish you all the best in graduating.

I'll help you find it. In the era of Android, the space for qt is getting smaller and smaller.

The stable work is inseparable from the use of embedded systems. For example, common electrical appliances at home, various communication equipment, mechanical instruments, as well as vehicles, automobiles, airplanes, etc., embedded systems play a very important role in aerospace, military applications, living furniture, industrial manufacturing and other fields.

Embedded systems are closely related to computer technology, because it requires the help of advanced computer technology, and on this basis, through the selection of different software and hardware configurations, to achieve the purpose of application. It is a system that has defined functional requirements and cost ranges, as well as resource consumption, and operates stably. This definition focuses on emphasizing the object and main purpose of the system, and is a more formal interpretation concept of embedded systems today.

The R&D process of embedded systems is designed with computer technology and semiconductor technology, which is a multi-technology work of an interdisciplinary fast platform. This reason makes it have the characteristics of multi-technology, high capital investment, relatively decentralized technology, and sustainable development. The main differences between it and the usual personal computer are:

It is professional, has a high degree of cost variability, and is more reliable in operation. In addition, the common PC operating system is more complete, with a complete data and program interface, and can directly execute related applications. When the embedded system works, the operating system can be ignored and the operation requirements of the application can be met directly through the chip, but the efficiency is low, therefore, if it is necessary to meet the multi-task parallelism, reasonably allocate resources, and make the efficient use of the dedicated interface function and the system function, the user is required to efficiently execute the software application by choosing the appropriate embedded manufacturing system by himself.

As the name suggests, an embedded operating system literally means a system in which the embedded system operates, mainly as a platform in real time. The embedded system is the most critical module of the whole system and plays a vital role. It is mainly composed of a variety of different software, interfaces, convex image interfaces and other small modules.

The embedded operating system completely surpasses the general-purpose PC system in some aspects, listed below:

1) Small size. Embedded systems have limitations in terms of resources, and by limiting their size, they can meet the hardware requirements of embedded systems.

2) Real-time. At this stage, many EOS are RTOS cores, and the real-time performance is very poor.

3) Good stability and very reliable. Through the task manager and reasonable scheduling methods, the applications on the system platform can run efficiently and stably.

4) Be portable. Embedded systems can work with a variety of different embedded processors and run freely on a variety of common platforms such as ARM.

5) Software and hardware can be cropped. Embedded operating systems are capable of trimming software and hardware, removing redundant parts and achieving a greater degree of simplicity.

6) Can be cured. Due to the limitations of the storage environment, embedded systems are often solidified to keep the memory space used as small as possible, usually in the ROM.

The efficient operation of embedded systems depends on a good EOS.

Generally, there will be data acquisition modules, IO modules, CPU modules, etc., which generally complete functions such as data acquisition, data processing, data display and control peripherals. The embedded real-time operating system generally has great advantages in the utilization of system hardware resources, the real-time nature of system task processing, and the starting speed and initialization speed.

Skylab's embedded WiFi modules have been widely used in the Internet of Things, home gateways, printers, set-top boxes, etc.

WiFi modules are divided into ordinary WiFi modules and embedded WiFi modules, and Wi-Fi modules are also known as serial port Wi-Fi modules.

So strictly speaking, the embedded wifi module belongs to the serial wifi module.

Used in smart sockets, it must be an embedded wifi module A very important difference between ordinary wifi modules and embedded wifi modules is that the power consumption is different, the power consumption of ordinary wifi modules is relatively high, and the embedded wifi module is specially born for the Internet of Things, and has made great improvements in power consumption!

The functions required by the smart socket are relatively simple and single, such as remote control of its on or off, etc., so the MCU used on the embedded WiFi module is enough to meet the processing function!

The application block diagram of the embedded wifi module application in the smart socket is as follows:

The embedded wifi module refers to a module, which is suitable for you.

The serial port wifi module refers to the fact that your development board or something else does not have wifi function, and it is used to connect.
