In software encryption protection technology, a common protection method is license authorization based on hardware fingerprint. This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program.
Hardware fingerprint encryption means that after a user obtains and installs the software for free, the software obtains some hardware information (such as the hard disk serial number and BO
(1) ft232r: ftdi (www.ftdichip.com) recently released a USB Interface Conversion Chip to convert USB to serial UART interfaces, or to synchronize, asynchronous bit-bang interface mode. Ftbench is a real cross-platform solution. It has versions suitable for various operating systems. It is prepared for the Linux kernel and the source code is open. It is part of the Linux kernel. It is easier to design and us

The serial port debugging software uartcmd.exe and the virtual serial port software vspm can solve the problem of no hardware debugging during serial port programming. The virtual serial port equipment is output through vspm, after the program sends information to the vspm device, it can directly display the informatio
Recently, due to the needs of the project, the need to get the machine's hard drive serial number and MAC address information, under C #, it is easy to obtain this information, but in the C + + program feel more trouble. After Baidu, found that a lot of prawns are through the WMI to obtain these hardware information, the network also has relevant code, through the actual debugging, but also found that it is indeed possible to obtain this information t
In the first article, I believe that many people can do this without reading it. However, anyone who has used the Microsoft SerialPort class has encountered this embarrassment. When the serial port is closed, the software will be deadlocked. Oh, my God, I am not so arrogant. Forget it. Don't be so absolute. 99.9% of people have encountered this problem. I think only half of them actually solve the problem. The other half closed their eyes and hoped th
Linux serial port description-general Linux technology-Linux technology and application information. For details, refer to the following section. I am a system integration engineer, so I often use notebook to debug the ROUTER or SWITCH in my daily work. However, when the operating system is changed to linux, I am dumb, I have also referenced some materials on the Internet. Based on my actual situation, the content is as follows:

On the internet to find a few examples of traversing the serial port, either the code is not complete, or there is a bug, such as reading the serial number is more than 10.After my finishing, now share the final code, VS2008 under the compilation.This method is also useful for traversing Windows power-on startup items with just a few modifications.void Cenumportdlg::enumport (void) {HKEY HKEY; LPCTSTR lpsub
After the ftdi chip can work, it starts the serial port test. We use the ft2232d chip board to expand two standard RS232 serial ports from a USB port. The test goal is to allow both serial ports to send and receive data at the same time.
Of course, software programming is used for testing. There are a large number of

Communication Mode
Parallel
Suitable for short distance communication, the parallel communication control is simple and the relative transmission speed is fast (8 bits are transmitted together).
Serial
Can only be transmitted by one person.
Sync (Understanding)
