40g transceiver

ObjectiveAbout the function of DMA (Direct Memory Access), the people who are concerned about me should know that I have briefly spoken on the F1 chip. There are netizens asked to explain in F0 the use of DMA transceiver serial data. Today should be a user request to summarize on the F0 chip, the use of DMA transmission (transceiver) Usart data functions.In a variety of chips (F0, F1, F2, F3, F4) know the f

In wireless communication, the nrf24l01 wireless transceiver module produced by Nordic is the choice of many players. It is GHz ~ The single-chip wireless transceiver chip in the GHz ISM band has the advantages of strong functions, convenient control, and low price. One piece of nrf24l01 can receive data sent from six channels at the same time, and change the communication channel to avoid wireless communic

http://xilinx.eetrend.com/article/7471With the advent of the NI pxie-5644r vector signal transceiver (VST), ni reshaped the concept of the instrument by introducing the flexibility of the user-programmable FPGA into the RF instrument.1. High performance and revolutionary designNI pxie-5644r VST combines typical RF I/O functions in a vector signal analyzer (VSA) and vector signal Generator (VSG) with NI or user-defined functions for signal processing a

Sometimes you have a can equipped processor in a low cost board but it has no CAN transceiver chips.Here is a method, the can be used to create a small experimental network with such a board.There'll is no noise immunity and you might has to lower the speed ....But many experimenters has made this work satisfactorily.Use a signal diode similar to 1n914 or 1N4148.Power supply diodes usually do not has a fast enough recovery time for CAN to function.Mod

Objective: To complete the network Port transceiver debugging process: NBSP;NBSP;1, network port initialization, according to the chip data sheet configuration 2, the number of network port, first to the TX FIFO in DM9000 to the data, and then sent to send the register to complete the sending; 3, network port reception. 1) Interrupt mode: DM9000 interrupts can be queried by proactively querying the DM9000 interrupt register, and by interrupting th

it is always bright, the optical port has a signal. If it is not bright, the optical port has no signal. FL Optical Transceiver optical fiber port and peer device Optical Fiber port connection/activity indicator. If it is always bright, the optical port is connected. If it is blinking, the optical port is connected and data is being sent or received. If it is not bright when the LFP function is enabled, the local or remote electrical

.connect (); Connecting to an SMTP serverIdsmtp1.authenticate;Idsmtp1.send (IDMESSAGE1); Sending mailboxes to the serverFinallyIf idsmtp1.connected then Idsmtp1.disconnect; Disconnecting from the serverEndEndAt this point, the mail messaging function is basically complete. To do a full-featured messaging management tool, you also need to join the Mail management feature. These functions are implemented primarily by manipulating files locally. This allows you to manage these messages in your own
