I have been writing a real-time operating system kernel over the past few days. I will make it public later, hoping to do my part for the development of domestic it. Recently, I have seen that many students and friends have no direction, so I wrote my experiences and shared them with you. I hope I can help my friends who just like me a little bit. In a twinkling of an eye, I have been studying and working in the IT industry for more than seven years. During this period, I used Web pages, MIS, da

Every time I read this article, I was touched by my admiration. I have been writing a real-time operating system kernel over the past few days. I will make it public later, hoping to do my part for the development of domestic it. Recently, many students and friends have no direction like me.So I want to share my experience with you and hope to help my new friends.In a twinkling of an eye, I have been studying and working in the IT industry for more than seve

I accidentally saw this article and felt shocked and truly talented. We hope that the ideal operating system can be completed smoothly. We hope that the operating system will not only be widely embedded, but also surpass Linux. The Chinese have their own chips and operating systems, and they hope that all IT personnel can fight for them. The reason why I reproduced this article is very simple. I think it is a honor to stick it on my own Bolg. I have been writing a real-time operating system kern

1 start with const int IYou know, when declaring a variable, int I is like this; this I may be re-assigned to it. As follows:Int I = 0;//...I = 20; // The value is assigned again here.However, one day my program may need such a variable (temporarily called its variable) and assign an initial value when declaring it. Then, my program will not assign a value to it in any other place. What should I do? Use Const.//**************Const int Ic = 20;//...

fields in the interface are final and static by default, which can be directly referenced by class names.Internal class Create:An internal class refers to placing the class definition inside another class. Sometimes reasonable use of internal classes can make the code more concise and make the program more clever. As a member of the external class, the internal class can access the private member variables of the external class. Let's take a look at the creation of internal classes in the follo

It is necessary to connect different ports of several kinds of IC together. Is it possible to connect them directly

I. Creation of the shanzhai Model In the shanzhai mode, some people say that the shanzhai mode is an imitation or plagiarism mode. I think it is very inaccurate to define this mode, at least in the electronic product industry. The Shanzhai model first appeared in Shenzhen and started with mobile phones and netbooks. Specifically, it is actually the IC design company that provides complete product solutions and services, product vendors only need to in

develop a lot of direct operations on hardware.I am no longer constrained by Microsoft's operating systems, development tools such as Vc and delhpi. I finally see another blank space. I like to follow the root of the problem.Software development and hardware are getting closer and closer.Lack of knowledge creates obstacles to my development, and chip technology is basically in the hands of foreign companies. This is a huge constraint on system-level design. A new product is coming out, the firs

Scenario: design a sub-module in a transaction system ------ fee deduction sub-module The fee deduction submodule consists of two parts: 1. IC card and transaction information The IC card includes two types of amounts: fixed amount and free amount. The transaction information Class records each transaction. 2. Deduction strategies There are two types of deduction policies: A. Fixed Amount of

Q1: What is NFC? NFC (near field communication) is a short-range wireless communication technology that uses the 13.56mhz band. Although the communication distance is only about 10cm, just like the non-contact IC Card Technology, you only need to touch it to exchange data between different electronic products. Unlike non-contact IC cards, NFC supports bidirectional communication. Data can be read or wri

The minimum interval between the leading edges of the "start bits of" consecutive characters sent by the terminal to The ICC shall is between and 266 ETUs as determined by the value of TC1 returned at the answer to reset (See sections 8.2 and 8.3). This interval is less than the minimum interval of ETUs allowed between, characters sent in opposite directions. If the value returned in TC1 are N, the ICC shall be able to correctly interpret characters sent by the terminal with a MI Nimum interval
