uart communication protocol

For network protocols, we have introduced them in previous articles. We usually stipulate network communication protocols. Therefore, some protocols in the network and communication fields are not so restrictive. The communication protocol we discuss here is the main, slave network which is based on RS-422 or RS-485 bu

The UDP protocol is non-connected and data block oriented. Therefore, the client side does not need to connect with the server side, send the message directly.server:1 #include This article is from the "Small Town Moss" blog, please make sure to keep this source http://fengbaoli.blog.51cto.com/10538178/1782254Inter-process communication based on UDP protocol

Internet TCP protocol is a basic network protocol, basically all network services are based on TCP protocol, such as Http,ftp and so on, so to understand the network programming must understand the TCP protocol based programming. However, the TCP protocol is a complex system

I have learned some useful knowledge about dynamic routing protocols. So I have studied the application of dynamic routing protocols in the network communication industry. I will share with you here, I hope it will be useful to you. Interconnect Networks use routes to send data from one network to another. In computer networks, the network ing between Online mobile groups and data transmission is completed dynamically using algorithms and protocols. T

ARP protocol features: by parsing Network Layer IPV4 Address to find a network transport protocol for the Data Link layer MAC addressARP Protocol FormatTable format with ARP protocol per unit 1,the normal communication between PC principle one ( both pc can access each othe

The biggest advantage of the network is that it saves time. Especially in business activities, it has outstanding advantages. With the continuous evolution of networks, we require more networks and the complexity of building network protocols. Now let's introduce the Fix protocol. The Fix protocol can be divided into two parts: Session-layer protocol and business

This is one of the most common protocols. Another kind of client-side protocol, such as the news app, clicks on a focus story and app jumps to the appropriate chann

With the continuous development of single-chip microcomputer applications, there are more and more multi-chip systems composed of multiple single-chip microcomputer, and information exchange between multiple single-chip microcomputer is a whole. The work of a single-chip microcomputer is divided into multiple single-chip microcomputer. On the one hand, the performance of the system can be improved, and on the other hand, the hardware design of the system can be simplified.Asynchronous serial por

1. You can write and read the register values (byte, word, and dual-word ); 2. You can set and reset components (v, M, S, Q, And I; 3. the on/off status of the component (v, M, S, Q, And I) can be read. 4. PLC Operation and stop can be controlled. Published the popular PPI protocol on the Internet. Although this protocol is incorrect, the idea is correct. There are many ways to communicate between Siemens

The legendary data is not encrypted at all.Just put the # (number)! Remove, the middle of those all minus 0x3c, then, four bytes a group, each byte takes six bits to make up the 6*4=24 bit, then divides into 3 bytes, this is a very classical base64 algorithm. But small changed some, mainly for the convenience of transmission convenient and convenient, because the 2,551 bytes reduced to 641 bytes, you can use other coding as the head and tail of the flag.The latest. NET Framework should already c

We all know the essential differences between IPv6 and IPv4 protocol networks. So what are the differences between the two in the two-way session communication process? The following describes the content in detail. The NAT-PT can only be used for applications that initiate a session by a terminal in the Ipv6 network, and the NAT-PT cannot be implemented if an application needs to initiate a session by a te

Network TCP protocol is a basic network protocol, basically all network services are based on TCP protocol, such as Http,ftp and so on, so to understand the network programming must understand the TCP protocol based programming. However, the TCP protocol is a complex system,

protocols exist as interfaces in Hadoop, and all 8 protocols inherit interface Versionedprotocol.The implementation of the Protocol is mainly concentrated in the classes: Jobtracker, Namenode, Tasktracker, Datanode 4 classes. whichJobtracker implements two interfaces: Intertrackerprotocol,jobsubmissionprotocolTasktracker class implementation: Taskumbilicalprotocol Namenode class implementation: Datanodeprotocol,clientprotocol,namenodeprotocolDatanode

This article has agreed:Dn:datanodeTt:tasktrackerNn:namenodeSnn:secondry NameNodeJt:jobtrackerThis article describes the communication protocol between the Hadoop nodes and the client.Hadoop communication is based on RPC, a detailed introduction to RPC you can refer to "Hadoop RPC mechanism introduce Avro into the Hadoop RPC mechanism"

Why did you suddenly want to study it? It is because you want to use MySQL for something, but you find that the client library, MySql Connector/Net, uses GPL authorization. In other words, source distribution cannot be closed. I heard that MariaDB uses the same communication protocol, so its client library can be compatible with MySQL. It is LGPL, but it does not have a. Net version. Oh, no such bullying. N

The communication protocol interface between the Applicationclientprotocol client and the Resourcemanage is located in Org.apache.hadoop.yarn.api, where the job submission client submits the application through the protocol, querying the application status, etc. The communication p
