Article Title: Linux Network Device Driver Programming. 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. This article only discusses the general Writing of network device drivers. The Code related to the hardware is omitted because of the different hardware specifications. Are there any mistakes or supplements? You are welcome to raise them. 1. Loading and uni

When you learn about linux network devices, you may encounter the problem of loading and detaching. Here we list a variety of commands for loading and detaching. Here we will share some of them with you. Hope to help you. If linux network devices including wireless devices are PCI compliant, first register the PCI device (pci_register_driver) with the kernel ), then, the probe function pointer in the pci_driver Data Structure initializes the PCI device and registers and initializes the linux net

the platform. It can be installed and detached by users at any time. The drivers of these peripheral devices are also called flow drivers, which can be dynamically loaded by the Device Manager at system startup or at any time after startup. These drivers usually exist in the form of DLL Dynamic Link Libraries. After the system is loaded, these drivers only run as user roles. The driver can be loaded by using the file operation API to obtain commands from the Device Manager and application. Typi

This article only discusses the general Writing of network device drivers. The Code related to the hardware is omitted because of the different hardware specifications. Are there any mistakes or supplements? You are welcome to raise them. 1. Loading and uninstalling the driver module If the network device (including wireless) is PCI compliant, first register the PCI device (pci_register_driver) with the kernel ), then, the probe function pointer in the pci_driver data structure points to the det

-key until you find the NIC registry information that is exactly the same as the target.After finding the correct Nic, click "Edit> New> string" in the drop-down menu, and the name of the string is "networkaddress". Double-click the name of the newly created "networkaddress" string, you can enter a value. Enter the new MAC address value you specified. The new MAC address should be a 12-digit number or letter with no "-", similar to "00c095ecb761.There are two ways to activate a new MAC address:I

interface types: PCMCIA wireless Nic, PCI wireless Nic, and USB wireless Nic. The PCMCIA wireless Nic can only be used for laptops, and the latter two can be used for desktops. PCI wireless NICs are designed for desktops Using PCI slots. They can directly exchange data with the computer memory independently of the host CPU, reducing the CPU burden. However, its disadvantage is also obvious, mainly because

without a built-in wireless Nic can also purchase a wireless Nic for the PCMCIA Interface or USB interface; for desktops, in addition to wireless NICs with USB interfaces, you can also purchase wireless NICs with PCI slots. In addition, there is a gprs wlan dual-mode card that not only enables WLAN wireless Internet access, you can also perform GPRS wireless Internet access (which will be introduced later in this article ). However, not every school

The PCMCIA wireless network card is installed for the notebook computer, but the NIC is not found in use. This situation can be resolved from the following two aspects. 1. View the wireless card signal light. The semaphore does not light up, the slot on behalf of the PCMCIA is not powered. Test with the replacement method to check that the PCMCIA slots a

The advent of the wireless network era allows people to get rid of the shackles of cable, anywhere can access a variety of networks, to people's work, life and entertainment brought convenience. Wireless network can not do without wireless card, how to choose the wireless card? The choice of wireless network card and ordinary cable network card purchase some different, we recommend that you consider the following aspects to buy the appropriate wireless network card. Type of wireless card (inter

encryption, SSID hiding, MAC address filtering and so on. Among them, MAC address filtering is a high efficiency security solution of small scale network, it authenticates the user's trustworthiness by checking the source MAC address of the user's packet. For advanced users, you can also establish their own dedicated security channel through the VPN function. In order to ensure the security of the wireless network, the use of firewalls is necessary, but for home users do not need to purchase a

HWINFO32 is a professional system Information tool that supports the latest technologies and standards. Allows you to check all of your computer's hardware. HWInfo can mainly display the processor, motherboard and chipset, PCMCIA interface, BIOS version, memory, and other information, but also provides the processor, memory, hard disk (Win9x) and CD-ROM performance testing capabilities. HWInfo is the most famous computer hardware test software in DOS

Messagebus mount U disk, to ensure that Haldaemon and Messagebus service startup, so this is also recommended to keep. Microcode_ctl can encode and send new micro-code to the kernel to update the Intel IA32 Series Processor Daemon.

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
