uart communication protocol

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, to full

copied together3. Go to the official Android website to download NDK, unzip, transfer to JNI directory in cmd, and execute absolute path \ndk-build4. Encapsulate a tool class yourself or use the SerialPort class directly, and give a direct use example:Direct plagiarism of the original project Serialportactivity.java, and a little change, focus on the change hereMserialport = Mapplication.getserialport ();This can be changed intoNew SerialPort (New File ("/dev/s3c2410_serial0"), 9600, 0);//com0,

to create a ServerSocketAfter use, call ServerSocket's Close method to close the socket.To be able to receive client requests all the time, the accept is usually placed in a dead loopExample: ServerSocket ss = new ServerSocket(20000); while(true) { Socket socket = ss.accept(); //通过Socket进行通信 } ss.close();using the socket for communicationUse the socket object directly on the client.Socket (Inetaddress,int Port)Create a socket that connects to a remote host, remote portFor example: socket

After the communication protocol is formulated, it may also be corrected and subsequent versions will be released. This may lead to the existence of communication protocols for multiple versions.Different clients may implement different communication protocols.But there is only one server program. How does it support

The SMTP protocol is a member of the TCP/IP protocol family, which is mainly about how to transfer e-mail from the sender address to the receiving address, which is the rule of transmission. The communication model for the SMTP protocol is not complex, and the primary focus is on sending SMTP and receiving SMTP: First,

Interface I'm going to finish this. Communication protocol resolution Besides, I always think I'm in the same nonsense. Here I also give myself these two days of the agreement resolution find a network storage to do a backup.

This article mainly introduces the C #-based UDP protocol synchronous implementation code, small series feel very good, and now share to everyone, but also for everyone to do a reference. Let's take a look at it with a little knitting. I. Summary Summarizes the synchronous communication of the UDP protocol based on C #. Second, the experimental platform Visual S

Http://liang8305.github.com/ios/itunsand iphone的 usbusb/ The first research on communication with the iPhone would take Google for granted the USB protocol. The iPhone must be connected to the computer through a USB cable. In fact, iTunes does not communicate with the iPhone through the TCP protocol.Usbmuxd ITunes uses something called usb mux to communicate with the iPhone, which provides a USB-TCP conver

Agreement: General occasions preferred HTTP-based restful API (based on HTTP protocol, interoperability is good, various programming languages are supported; good scalability; loose coupling; easy to test) API implementation techniques should avoid coupling with clients Special occasions can choose the Binary RPC protocol (low latency, real-time requirements very high; loose coupling is not impo

It is mainly a software platform applied to industrial applications. This article focuses on communication ideas. Hope you can advise me !!!

1 -- protocol The memcached client communicates with the server over TCP (UDP interfaces can also be used. For details, see "UDP ). A given running memcached server listens for connections on a (configurable) port. The client connects to the port, sends commands to the server, reads feedback, and closes the connection. There is no need to send a special command to end the session. The client can close the connection when it does not need it. Note:

Tcpdump is a powerful protocol layer analysis tool in linux. it can be used to monitor network communication and locate network-related bugs. for example: whether a connection is created between the client and the server, the client sends a message, the server does not parse, or the client... tcpdump is a powerful protocol layer analysis tool in linux. it can be

just have to make a little change, change the batchsize to 2, and the situation is very different. $cursor = $c->find ()->sort (Array (' name ' = 1);$cursor->batchsize (2)->limit (10);$cursor->getnext (); Item 1$cursor->getnext (); Item 2Var_dump ($cursor->getnext ()); Item 3 As can be seen, although the first network return package is set to return only two data, but every three times the getNext is returned data, that is, the second time from the server to obtain da

But here's a special case, when BatchSize is set to 1, or negative, MongoDB only returns the first requested packet, and then shuts down the connection directly. In other words, if we execute the f

Haven't written a blog for a long time, the previous period busy doing projects, delayed some time, today began to continue to write ~Today, the simple application of socket communication, about what is the socket and some of the basics of network programming, is not mentioned here, only the most simple to understand the practical things.1, first look at the TCP protocol based on the socket server and clien

Flash 5 starts by transmitting data to the server in XML or "variable/value" pairing output format. While this data can be parsed automatically by the Flash compiler or manually by the developer's own code, parsing is slow. Because XML needs to process data on a per-node basis during parsing. And the data types processed using XML and the "variable/value" pairing format can only be character-type, and numbers are no exception. Instead, flash remoting can handle complex data types, such as object
