Embodiment
In order to understand the present invention better, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, it illustrates the process flow diagram of the hardware button control method that the embodiment of the present invention provides, its application has in polymorphic electronic equipment, as having common notebook form and ipad(panel computer) in the electronic equipment of form, the structural representation of electronic equipment 200 can be consulted shown in Fig. 2, can include but not limited to: first processor 201, second processor 202, be connected to the South Bridge chip 203 between described first processor 201 and described second processor 202, described first processor 201 runs an operating system, described operating system can complete the function of hardware button by the driver calling hardware button.Namely when operator operates some hardware button, the function that the driver complete operation that operating system can call this hardware button will perform.
As increased Volume Up(volume as operator) this hardware button is when carrying out pressing operation, and represent that operator wants current volume to tune up, operating system then can be called and increase volume this driver to increase volume.
In embodiments of the present invention, hardware button control method can be performed by the second processor in electronic equipment, can comprise the following steps:
101: the state situation of change obtaining hardware button, the state situation of change of hardware button shows the function of the current execution of hardware button.
Be understandable that: when operator wishes to control electronic equipment by hardware button, when making hardware button perform the function of self, operator operates hardware button, now the state of hardware button changes, and therefore the state situation of change of hardware button can show the function of the current execution of hardware button.
When such as: operator is reduced by Volume Down(volume) this hardware button controls electronic equipment reduction volume output, operator can directly press this hardware button.Operator often presses hardware button once, and the state of hardware button then can change, and electronic equipment then can perform the function that volume corresponding to hardware button reduces.
102: the state situation of change of hardware button is sent to South Bridge chip, to make South Bridge chip, state situation of change is sent to first processor, and the operating system run by first processor calls the driver of hardware button, has carried out the function of the current execution of hardware button.
In embodiments of the present invention, South Bridge chip is as the communication bridge between first processor and the second processor, after the state situation of change receiving the hardware button that the second processor sends, the state situation of change of hardware button is sent to first processor, such first processor then can analyze the state situation of change of hardware button, and what obtain that current state changes is the function which hardware button and this hardware button current perform.The operating system operated in afterwards on first processor then can call the driver with this hardware button function, is completed the function of the current execution of hardware button by other devices in driver drive electronics.
What the state situation of change of such as hardware button showed that current state changes is that VolumeDown(volume reduces), and need to reduce volume output, then operating system can call the audio process having the driver reducing volume output function and come in drive electronics, and the volume reducing audio process exports.
Pass through technique scheme, have polymorphic and comprise the electronic equipment of first processor and the second processor, when no matter it runs non-x 86 operating system or x86 operating system, electronic equipment can obtain the state situation of change of hardware button by the second processor, and the state situation of change of hardware button is sent to South Bridge chip, to make South Bridge chip, state situation of change is sent to first processor, and the driver that the operating system run by first processor calls hardware button completes the function of the current execution of hardware button, such electronic equipment is when operation system, just do not need to increase driver for message conversion outward in operating system, reduce extra program support.
