I have a piece of stm32f429 discovery Board, for some reason need to use 8080 interface lcd, and the block Development Board comes with the LCD interface using LTDC drive, so on the right atom here bought a 4.3 inch capacitive touch screen, driver IC for the NT35510.In order to quickly build a software engineering, I use the STM32CUBEMX tool to generate code templates, and write the LCD.C and nt35510.c two
1. Overview
With the development of telecom technology and business, the competition in the telecom market is becoming increasingly fierce. In the fixed-line telephone market, mobile's distribution of fixed-line voice services is intensifying. In the broadband market, the dominant position of the value chain is gradually lost. In the wireless market, the growth of PHS is weak. These are a true portrayal of the severe challenges facing fixed network operators in China, and are also the main drivi
I. Huge Market Demands
Users' needs are the most basic driving force of FMC. With the emergence of a wide range of IP multimedia applications on the Internet, the majority of end users are no longer satisfied with the use of PC terminals to access the Internet, but want to use a multi-functional mobile terminal, no matter where to move, the access method, such as Cellular mobile Cellular system, Wi-Fi/WiMAX coverage, and indoor ADSL/Cable access, can
Due to the differences between the fixed network and mobile network in terms of access bandwidth, terminal authentication, and terminal mobility, how to view and solve these differences has become a key issue for IMS-based FMC.
The concept and architecture of IMS was initially proposed by 3GPP In R5. As a new domain in the third generation mobile communication, IMS provides multimedia services for users and achieves separation of business and control.
One: Functional interface1. The concept of a functional interface is that this interface must have only one abstract method, which can be displayed by @functionalinterface (similar to @override), but an interface with no such annotations but only one abstract method is also a functional interface ; (Interfaces also hav

The base class baseoutput explicitly inherits an interface ioutput, and the class trackoutput inherits baseoutput, and also inherits the ioutput interface. Assume that ioutput has a method output, so there are two output methods in trackoutput, one source is the base class baseoutput and the other source is the interface ioutput. This leads to confusion. What sho
List interface, Set interface, Map interface, list interface setmap1. The List and Set interfaces inherit from the Collection interface, while Map is not the inherited Collection interface.
Map does not inherit the Collection
The base class Baseoutput explicitly inherits an interface Ioutput, after which the class Trackoutput inherits Baseoutput, and the Ioutput interface is inherited at the same time. Suppose Ioutput has a method output, so there are two output methods in Trackoutput, one from the base class Baseoutput, and one originating from the interface ioutput. This has led to
(i) Collection framework: The Java language designer has made some specifications (interfaces) and implementations (classes that implement interfaces) for commonly used data structures and algorithms. All abstract data structures and operations (algorithms) are collectively referred to as the collection framework.Programmers in the application, do not have to consider the data structure and algorithm implementation details, only need to create some objects with these classes, and then directly

IntroductionInterface is a very important element in object-oriented programming language, it is described as a set of services, for the client, we are only concerned about the services provided, but not the implementation of the service, for the service-side class, if it wants to implement a service, to implement the interface associated with the service, It also does not have to interact with clients that use the service too much. This good design m

PrefaceFrom the fifth round to the seventh round, we useATL writes a simple COM component, which is simple because only one custom (IFM) interface ifun is implemented in the component. Of course, if you want to be lazy, we can add all 200 functions to this

I can't remember when I found such a useful article, but I wanted to translate it and share it with myself.
After a long time, in 2014, I finally calmed down and spent a lot of time translating the image into Chinese. I am a programmer who can only pass the cet6 score in my
Objective:When we define the members of an interface, we do not need to write the access control, because it is the default public and can only be public. When a class is to implement this interface, it is natural to expose its members. I've been doing this for a long time.Interface Interface1 { string GetName (string name); }Class Class1:interface1 {public string GetName (string name
hard Disk Interface
The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all hard drive integrated controller design belongs to IDE,SCSI is no exception. Of course, with
