Fluke Networks: function of Link LED indicator in Fault Diagnosis

One of the most common faults in the daily network is that the site cannot access the Internet. PC users or network maintenance personnel should first look at the NIC, switch, or HUB indicators to determine whether the connection is normal. This is usually the correct procedure for fault diagnosis ), then, check the software settings on the PC. But is it possible to determine the cable or port problems through the LED lights on the NIC or switch? It h

Analysis of energy-saving principle of LED display

LED display of energy-saving concept quietly set off, become its most attractive to consumers eye highlights, but also in recent years, the cause of hot growth. Of course, after years of frenzied growth, the industry is now mired in a stalemate to shuffle the trap. In this dilemma, there must be many enterprises affected by this impact and the vitality of the big injury, or even bankruptcy, of course, there will be many enterprises to get out of the h

Seventh chapter LED will blink for me: Control curtain J Light emitting two-stage tube

First, the realization principle of LED driveAlthough the Linux driver deals directly with hardware, it is not the Linux driver that writes data directly to the memory in the hardware, but interacts with the native I/O memory. Every hardware connected to Linux has a map header address in I/O memory, and the LEDs on the board have their first address.Second, write led driverFirst step: Initialize the Cdev wi
