uart communication protocol

protocol, pay attention to the following points: 1. When the bus is idle, both the user processor and the servo processor are in the read data state. When one party needs to send data, it is set to write state. 2. In the synchronization or data transmission phase, if the timeout does not receive a corresponding response, the sender should convert the status to the read status. It is mainly used to process the data that both parties need to transmit

SPI Communication Protocol The SPI is a synchronous serial communication interface.SPI is the abbreviation of English serial Peripheral interface, as the name implies is the serial peripheral device interface. SPI is a high-speed, full-duplex, synchronous communication bus, the standard SPI also uses only 4 pins, comm

other networks, messages that contain the Modbus protocol are converted to frames or packet structures used on this network. This transformation also extends the method of addressing the node address, routing path, and error detection based on the specific network.1, transmission on the Modbus networkThe standard Modbus port is a RS-232 compatible serial interface that defines the PIN, cable, signal bit, transmit baud rate, parity of the connection p

The pioneers in the converged communication field are currently sending the Session Initiation Protocol (SIP ). SIP has become the main protocol for VoIP and other real-time media communications on the packet network. There are several reasons for the popularity and success of SIP. First, SIP is regarded as a protocol

The AMF (Action message Format) is used very frequently in the development of Flash/flex applications, and is more efficient than ordinary HTTP, WebService soap and many other data communications, and has been tested in this regard, Detailed access to: http://xinsync.xju.edu.cn/index.php/archives/2162. This article will combine FLUORINEFX to provide communication service interface, in the client through flex to access, a simple introduction of the use

GH0ST Communication Protocol Resolution (2) Starting from the active connection of the controlled side to the main control end. All things in the world, the beginning of the Universe universal Power is the force of God that push. Of course, the interaction between the host side and the controlled side is always initiated from the controlled side to the main terminal, so let's start with the initiation of th

thread is busy, and the current CPUThere is also the ability to run a new thread, then open a new thread for the completion port service. If the load capacity of the current CPU is not enough, then kill the self-threading function appropriately. I thought there should be a logical branch that handles the active end of its own thread in this place of adjustment, because when the socket is closed, there are the following operations while (M_NWORKERCNT) { postqueuedcompletionstatus (m_hcompletion
