Abstract

The invention relates to a method for real-time processing system key on the embedded device, wherein it comprises: in the control system, building one information queue processing process (1) and one input device signal receiving process (2); the process (2) receives the input device signal of device driving program, to transmit received information to the process (1) which will judge the layer sequence of window, based on the information content and the pointer of window Z to decide the information object and the information type, and starting the interruption mechanism, and using relative function interface function. With said invention, the user can directly use relative function key to use other functions without leaving present interface. The invention can be used in mobile phone, etc.

Description

technical field [0001] The invention relates to a method for processing system keys in real time on an embedded device. Background technique [0002] With the increasing number of embedded devices such as Mp3, recording, and mobile hard disk functions added to mobile phones or digital cameras, users have higher and higher requirements for the convenience of device functions. These devices can incorporate special system keys, such as dials, etc. to handle various functions. When the user presses the corresponding system key to handle the corresponding function, the interface system is required to provide support. However, in the currently known technologies, only corresponding key values ​​can be processed according to the current display interface, and corresponding functions can be invoked. If you want to switch to other functions, the user can only process other key values ​​of the system by opening another function interface. For example, Mp3 control, assuming that the...
