encoding. In fact, fimc provides the clock required for camera operation. 2. driving development ideas Because the driver is a bridge between hardware and software, we need to understand the two aspects of camera driver development: first, the hardware interface of the camera, that is, how it is connected to the chip,

In the first half of this year, I transplanted a Linux driver to a common vimicro camera on the market to an Embedded Development Board. The development environment is: OS: linux2.6.9 Compile: Cross 3.3.2 CPU: Intel PXA270 Camera type: vimicro zc301p + hv7131r The driver sou

Embedded Linux Driver Development processIn embedded systems, the operating system is driven by a variety of drivers to control hardware devices. A device driver is an interface between an operating system kernel and a hardware device that shields the application of hardware details so that, in the application's view,

using third-party sources, useyum listThe command cannot find the driver related to Nvidia, and then add the rpmfusion source, such: Use againyum listSearch for the Nvidia driver and obtain the following results: Finally, useyum install akmod-nvidiaInstall it.

The development of Linux drivers differs greatly from application development, which leads to the essential difference between writing a Linux device driver and writing an application. First, user state and kernel state The

, if the packet traffic is high, excessive interruptions will increase the system load. Round Robin If the polling method is used, you do not need to enable the interruption status of the network device or register the interrupt handler. The operating system will enable a task to regularly check the BD table. If the current Pointer Points to the BD not idle, the data corresponding to the BD will be retrieved and the BD will be restored to its idle state. Because the principle of regular task che
