, such as Ethernet, T. R., FDDI, ATM, SOCC, and SLIP. A non-TCP/IP network is used to provide a communication path that replaces TCP/IP for HACMP to monitor nodes in the HA environment (Cluster, it can be used to connect nodes with RS232 serial lines, or set the scsicard or SSA card of each node to the Target Mode. 1. Two servers (host A and host B) Running the Hacmp software simultaneously; 2. The server serves as the backup host of the other Party i

the RS232 interface, but uart1 and uart2 are not obtained from the RS232 port, instead, the corresponding COM1 and con3 pins are obtained respectively. During the test, the RS232 conversion circuit is required. Therefore, you need to modify the above Code to enable the corresponding device. Modify as follows: Int devicespeed = b115200;Int ttyspeed = b115200;Int

RS485is a physical interface, simply said to be hardware. MODBUSis an international standard communication protocol for exchanging data between different vendors (typically industrial use); so-called agreements can also be understood as the "language" mentioned above, it is simply software. RS485 belongs to the wired transmission, so it is necessary to hardware transmission media, the actual is two lines on it, in this two is the actual transmission line is the same signal, just send the signal

There is a project that uses the PC104 board (PCM-3341), the Linux system. But at least 3 RS232 in the project, see Datasheet, enough. The board has 3 separate RS232 and a rs232/485 multiplexing port. But in the actual test use, encountered a problem. 1 and 2 can work (later found to be problematic, reading sensor data, reading is not complete), but 3 and 4 have

Qt serial Port class Qserialport use notes Although the RS232 interface is no longer available on most home PCs today. However, due to the simple operation of RS232 serial port and reliable communication, there are still a lot of applications in the industrial field. Qt Previous version, did not provide official support for the RS232 serial port, writing serial

), unable to program flash outside the processor.Program download using the XMODEM protocol is a common practice for many products, such as Cisco's router products, Huawei's ISDN terminal products, which use the Windows-brought HyperTerminal software to transfer files without the need to install proprietary software. Simply add a break to the target board to implement the Xmodem protocol "diagram 1", it is easy to implement the program or data file download. In the following paragraphs, the impl

fully compatible with the layout. In desperation, I used the crossover-office-pro-bin tool to install msoffice. To put it bluntly, crossover office is a commercial product based on wine. It provides a simple method for installing the ms software in linux. Basically, it can achieve better results without configuration, in fact, it is very convenient to install msoffice with wine, but it will be a little mo

currency to wait and see.6. When the Trix line moves down below trma for a long period of time and the share price has fallen sharply, if the Trix line shows signs of flattening or turning up at the bottom, once the stock price increases with a large volume of transactions, investors can build a small amount of data in a timely manner.7. When the Trix line breaks the trma line again, it indicates that the stock price will rise again. Investors can buy it in time and their shares will be up.8. T

about evolution. Obviously, we need to understand what evolution is. You may think that I lied to you, but in fact, evolution only has three dimensions: select, crossover, and mutate ). Let's continue to understand the evolution.Select Select is the choice, why, because the survival of the fittest: Individuals in the population cannot be idle and have to go to school to raise their wives. Therefore, they need to pass various examinations and assessm

Article Title: run a Windows application on a Linux operating system. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Most Linux users are familiar with WINE programs. WINE programs can use Windows software without Windows. WINE is still relatively mature, but WINE can only run some programs, and some programs may encounter some problems when running. 　　 In a

of ADSL Internet sharing cannot be achieved. Under normal circumstances, the purchased ADSL Broadband modem will give a random network cable, which is usually a cross-network cable, that is, one end of the network cable is produced according to the 568B wiring standard, the other end of the network cable is produced according to the 568A wiring standard. However, when observing whether the network cable belongs to a crossover network cable, you only

Python implements simple genetic algorithms and python Genetic Algorithms Today, I sorted out the code I wrote and found that the genetic algorithm written in python during the dashboard process was quite interesting. I 'd like to share it with you. First, the genetic algorithm is an optimization algorithm that simulates the survival of the fittest of genes for computation (the specific idea of the algorithm is not described in detail ). The process is divided into initialization code, individua

What are the search algorithms currently in the computer?Depth first, breadth first (derived from data structure)Exhaustive method (list all possible), backtracking (depth-first thought plus return search) derived from algorithmic design and analysisMountain climbing method, simulated annealing, genetic algorithm (intelligent algorithm) are some adaptive random search algorithm, (somewhat similar to the uncertainty algorithm, but also some heuristic algorithm (ant colony algorithm is also heuris

1. Introduction to Genetic algorithmsGenetic algorithm, a computational model that simulates the evolution of natural selection and biological Evolution , is an algorithm that constantly chooses good individuals. When it comes to genetics, think about the nature of animal genetics, the main process of nature, including chromosome selection, crossover, mutation, after these operations, to ensure that the future is basically the best, then continue to i

central memory will be very high, so the switch kernel becomes the bottleneck of performance implementation; the other is the crossover bus structure, which can establish direct point-to-point connection between ports, which is good for single point transmission, but not suitable for multicast transmission; Three is a hybrid crossover bus structure, which is a hybrid
