Debug fiber Interface interface with FPGA:Due to the needs of the project, the previous period of time debugging the optical fiber interface, recording some design experience.In the design, FPGA is used to control optical fiber module to complete the transmission of optical fiber data, FPGA uses Xilinx company's Spartan6 lx45t, because of its internal 2 GTP transceiver, can be used as a variety of communication protocol (Gigabit Ethernet, Pci-e,sata,

protocol stack send function, to achieve data wireless transmission③ Receive: Receive node calls the protocol stack wireless receive function, realizes the wireless data receivesSince the protocol stack encapsulates these functions, it is convenient for us to use them. Here is the protocol stack wireless send function:A better application of the protocol stack requires a detailed understanding of the specific role and significance of these functions and their parameters provided by the protocol

are no special application requirements, it is advisable to select the device in these two companies.Hardware Resources for 5.1.2 devicesHardware resources are important criteria for device selection. Hardware resources include logical resources, I/O resources, cabling resources, DSP resources, memory resources, phase-locked loop resources, serial transceiver resources, and hard-core microprocessor resources.The need for logical resources and I/O res

number of tasks of Integrated Wiring. However, twisted pair wires have weak anti-aging capabilities, and only one image can be transmitted at a time. Therefore, it is suitable for video surveillance of network cameras in medium and short distances, with relatively scattered camera points, or with relatively close but concentrated points, such as banks, hotel chains, supermarkets, or university campuses. Optical fiber.Optical Fiber Transmission has the following advantages: long transmission dis

parabolic surface, so that the antenna is located in the parabolic surface of the internal reflection focus, through the electromagnetic waves reflected in the focus of the formation of energy concentration, thereby enhancing the electromagnetic signal transceiver, To achieve enhanced signal in a specific direction. The key to making a simple gain antenna is to find a more regular metal parabolic surface and compute the focus position of the parabo

direction, and if any network segment are severed, all network transmission ceases. A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic (traffic), and the traffic generated by each station have equal Tran Smission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously (simultaneous), they use a media access control technology such as car

multicast distribution service, is a broadband point-to-point access system that can access voice, data and video services. LMDS system using millimeter wave transmission, working in the 20-40ghz band, can provide up to 155.52Mbps user access rate, known as a "Wireless optical fiber" access system. In addition, the LMDS system supports all major voice and data transmission standards, such as ATM, TCP/IP, and MPEG-2.The *LMDS system adopts a kind of honeycomb structure configuration, by which on

Spring for beginners in Java sshIn this article, I learned two ways of dependency injection: Set Value injection and construct injection. In our previous thinking, if we call a class, we need to manually instantiate it. When we create a called job that does not need to be completed, this is the control reversal, when the called instance process is completed by Spring and injected into the caller, this is dependency injection. I. First, let's learn how to set value injection. First, we will creat

The gamepad f310 game controller of Logitech needs to be transplanted to the Android system, so it took two days to detail the main development logic process. 1. First test on PC and Linux: Install the Logitech driver on the PC. For general Linux platform installation: Use the gamepad in Ubuntu:1. Install the handle DRIVER:# Modprobe joydev2. Install the handle testing software:# Sudo apt-Get install joysti

The ink simulation driving software is divided into Standard Edition, Home Edition and Professional Edition. The three versions of software feature just the same operating hardware that is supported. Standard Edition support keyboard mouse driving or the use of ordinary game steering wheel (that is, only the accelerator pedal and brake pedal, the stall can only be through the button or dial or dial to add and subtract), permanent free. Although the ordinary game steering wheel has only 2 pedals

One more note is that the cascade between the hub devices is usually done through a cascading port, and that the interconnection between routers and hubs is done through a normal port. In addition, the router and hub dev
