I. What is IOCTL?IOCTL is a function used by the device driver to manage the device's I/O channels. The management of the I/O channel is to control some features of the device, such as the Serial Transmission baud rate and the motor speed. The number of calls is as follows: Int IOCTL (int fd, IND cmd ,...); FD is the File Identifier returned by the open function when the user program opens the device. CMD i

Control the LEDs via a string;2. Control the LEDs with the I/O command.Test LED Driver:1. Test led driver

Some time ago, I switched from Fedora8 to Fedora9 and wrote some experiences when installing Fedora9. Installing the Nvidia graphics card driver is still a headache. In the experience, I first tried to disable ABI to use the nvidia graphics card driver, but the effect was not satisfactory and there were still some problems. I started to try to downgrade the software library by using the Xorgxserver of the o

Sometimes you may want to knowLinuxSystemNicWhat driver is being used. The following describes how to solve this problem. 1. Whether it is an integrated network card or an independent network card, you must connect to the PCI bus in some way. In this case, there must be a code, which can be obtained through the following command: # lspci | grep Ethernet 02:00.0 Ethernet controller: Intel Corporation 80003ES

For driver problems, ioremap and (* (unsginedchar *) virtual_addr0xff are used to assign values-general Linux technology-Linux programming and kernel information. For details, refer to the following. The source code looks like this: The platform is ARM9. Virtual_addr = ioremap (phy_addr, 1); virtual_addr is a peripheral Register address in two bytes; * (Unsigned int *) virtual_addr = 0 xffff; The progra

The wireless driver is successful, but the udev interface cannot be renamed, and thus the wireless network-Linux general technology-Linux technology and application information cannot be used. For more information, see the following. The wireless network driver is successful, but udev renames the interface, so that the system cannot find the interface and thus ca
