Embodiment Construction

[0024] In order to better understand the present application, the embodiment of the present application takes the direct control of the flash light switch in the Android system as an example for illustration. It should be understood that the operating system referred to in the present application can also be other operating systems such as ios, mac os, and hardware devices It can also be a camera, bluetooth, sensor, microphone, etc. in an electronic device.

[0025] The present application will be further described below through specific examples.

[0026] In the embodiment of the present application, by implementing the kernel driver (flashlight driver) in the Linux kernel space (Linux Kernel layer) and implementing the hardware abstraction layer interface in the user space, to provide a hardware access interface to the upper layer, that is, the Android system The application framework layer provides hardware services. Because the application program of the Android system is...

Abstract

The invention provides a method and a module for directly controlling hardware equipment in an operating system, wherein the method comprises the following steps that an linkbase loading instruction is firstly obtained, and a linkbase is loaded; after an instruction for controlling the action of the hardware equipment is obtained, functions corresponding to the action instruction of the hardware equipment in the linkbase are called; then, a called function realization function is executed for controlling the hardware equipment to execute the corresponding action, so that the direct control on the hardware equipment is realized.

Description

technical field [0001] This application relates to the development of an operating system for electronic equipment, in particular to a method and module for directly controlling hardware equipment in the operating system. Background technique [0002] Please refer to figure 1 , is a schematic diagram of the architecture of the Android (Android) system. [0003] The first layer 101 is a Linux kernel driver layer (Linux kernel), which is implemented by C / C++. Android core system services depend on the Linux kernel, including security, memory management, process management, network protocols, driver models, etc. The Linux kernel also serves as an abstraction layer between the hardware and software stacks. In addition to the standard Linux kernel, Android also adds kernel drivers, such as: Binder (IPC) driver, camera driver, power management, etc. [0004] The second layer is a component library and a virtual machine layer, wherein 102 is a component library layer (Libraries)...
