uart communication protocol

As a modern network, we divide it into seven levels for learning. The Protocol content varies with different levels. Now let's take a look at the relevant network communication protocols. First, let's take a look at what network communication protocols are. ◆ Introduction All parts of communication must agree with a se

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management needs. The industry has explored two ways to s

Source: Design of communication protocol in embedded systemThat's wonderful!Companies do projects, embedded systems are large and small, everywhere. Because all are in a system, so all need communication, since the communication is related to the protocol problem.Talking abo

Test routine for interrupt receiving and sending of single-chip microcomputer C51 serial port (including the implementation of communication protocol) Author: Yan Jianwei http://www.gjwtech.com Communication Protocol:1st bytes, MSB is 1, 1st bytes, 2nd bytes, MSB is 0, not the first byte, and so on ......, The last by

The concept and elements of communication protocolIn the OSI Open Interconnect Reference Model, the data units between peer entities (peer) are encapsulated in the sender Layer (encapsulation), and the receiver is parsed (decapsulation) on a per-layer basis. The packets that the sender N-tier entity obtains from the N+1 layer entity are called Service data UNIT,SDU. N-tier entities only tr

.2. Basic concept 2-1, messageFirst there are three basic concepts that we need to discuss before we start: message, message protocol, Message Queuing. The message is both a carrier of information and a description that the reader can understand. in order for both the message sender and the message receiver to understand the information that is hosted by the message (the message sender needs to know how to construct the message, and the message recipi

Presumably, mobile phones are no longer familiar to everyone. Its biggest feature is mobile and wireless. So do you know the protocol principle? This article will introduce you in detail the wireless communication protocol, that is, the meaning and related content of WAP. WAP Wireless Communication

I. INTRODUCTION and Agreementpreviously developed a project-in-vehicle navigation system. The first problem encountered is how the hardware device communicates with the server. The key is the communication protocol!As we all know: in order to realize communication, communication agreement must be reached by both partie

3G communication technology has been widely used and is evolving to 4G. The number of access stations and transmission points in the communication network has increased exponentially, and there is still a rapid growth trend. The communication network's site network capabilities and local fault recovery protection mechanisms have also become more demanding. The Op

Before I did the game, my main task was to implement various communication protocols based on TCP, UDP or serial port. When I want to design a TCP-based network game protocol, the feeling should be very simple, before the various international standards of the agreement has been implemented, the custom protocol is not extremely easy. But the fact that I finished

DICOM3.0 standard in the Communication Services Module described in the Dimse classified asPresentation LayerTo indicate the underlying services provided in the DICOM protocol, that is, the provisions of the DIMSE protocolService Primitives(Service Primitives), which communicates services between the peer Dicom application entity (application entity). As shown in the following: Here the so-called Dicom app

server via the HTTP protocol. After the Web server is received, the transaction is processed, and the results are passed back to the Web browser via HTTP to display the requested page on the Web browser. (4) Close connection: When the answer is finished, the Web browser and Web server must be disconnected to ensure that other Web browsers can connect to the Web server. The commonly used HTTP header information is: ①http 1.0 OK this is the first line

Introduction:This program and rs232_client constitute a complete demo system, showing the application of PHP in RS232 serial communication.A basic but complete RS232 Communication Protocol (HQB232) is implemented in the program, and the communication protocol format is as follows:Protocol content:C->s 01//Request News

Abstract: With the development of computer networks, it brings resources sharing to people. At the same time, there are great security risks in data security. The TCP/IP protocol is widely used for communication in today's networks. This article analyzes computer network security issues based on TCP/IP communication protocols and explores corresponding network se
