Abstract
The invention discloses a method for controlling a system by using a vehicle-mounted android platform based on soft keys, and aims to provide a method for controlling the vehicle-mounted android platform, which is not limited by an input/output (I/O) port of a chip and the number of physical keys. The method comprises the following steps that: android equipment receives a signal of the physical keys and samples the signal; and an android system of the android equipment receives the sampled signal and displays a soft keyboard on a specific display area of a liquid crystal display (LCD). The invention also discloses the android equipment manufactured by the method. The method can be used for the vehicle-mounted android equipment.
Description
Technical field
The present invention relates to vehicle-mounted Android platform, especially relate to method and the Android equipment of a kind of vehicle-mounted Android platform based on the soft-key button control system.
Background technology
Now on the Android equipment, intercommunication have a cover own from descending on communication mechanism.But there is certain limitation in existing communication mechanism.Physical button like traditional Android equipment realizes through the I/O mouth that with communicating by letter of Android system end its structure principle chart is as shown in Figure 3, and physical button directly is connected through the I/O mouth with the Android system end.The communication means of existing physical button and Android system end is as shown in Figure 4.Physical button is pressed, and sends signal through I/O mouth Android system end, and the Android system end receives said signal and does handled (promptly ejecting soft keyboard).But this kind communication mode need take the I/O mouth, and the I/O mouth of each chip is very limited.
Therefore, be badly in need of a kind of new communication mechanism of exploitation.
Summary of the invention
The present invention realizes through the I/O mouth with communicating by letter of Android system end for the physical button that solves prior art Android equipment; This kind communication mode need take I/O vocal imitation skill problem, and method and the Android equipment of a kind of vehicle-mounted Android platform based on the soft-key button control system are provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is the method for a kind of vehicle-mounted Android platform of design based on the soft-key button control system, comprising:
Android equipment receives the signal and the sampling of physical button;
The Android system end of Android equipment receives said sampled signal and demonstrates soft keyboard in the particular display area of LCD.
Said Android equipment receives the signal and the sampling of physical button through MCU.
Said MCU sends sampled signal through UART to the Android system end.
Said vehicle-mounted Android platform comprises also that based on the method for soft-key button control system whether said Android system end detects the soft keyboard zone by correct click, if then trigger key-press event of simulation.
The present invention also provides a kind of Android equipment, comprises physical button, Android system end and LCD, and said Android equipment also comprises: the physical button detection module, and it receives the signal and the sampling of physical button;
The Android system end receives said sampled signal and demonstrates soft keyboard in the particular display area of LCD.
Said physical button detection module is MCU.
Said MCU sends sampled signal through UART to the Android system end.
The present invention receives the signal and the sampling of physical button through utilizing Android equipment; The Android system end of Android equipment receives said sampled signal and demonstrates soft keyboard in the particular display area of LCD; Thereby abandoned traditional scheme that the I/O mouth comes directly to connect physical button and Android system end of passing through, can not receive the restriction of chip I/O mouth and the restriction of physical button quantity.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the present invention is elaborated, wherein:
Fig. 1 is the process flow diagram of the vehicle-mounted Android platform of the present invention based on the method for soft-key button control system;
Fig. 2 is the schematic diagram that adopts the Android equipment of method making shown in Figure 1;
Fig. 3 is the schematic diagram of existing Android equipment;
Fig. 4 is the process flow diagram of the communication means of prior art physical button and Android system end.
Embodiment
See also Fig. 1.The vehicle-mounted Android platform of the present invention comprises based on the method for soft-key button control system:
The first step: Android equipment receives the signal and the sampling of physical button;
In this specific embodiment; Android equipment receives the signal and the sampling of physical button through MCU; MCU sends sampled signal through UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous reception/dispensing device) to the Android system end.Adopt UART communication higher than I/O port communications accuracy rate.
Second step: the Android system end of Android equipment receives said sampled signal and demonstrates soft keyboard in the particular display area of LCD.
The 3rd step: whether said Android system end detects the soft keyboard zone by correct click, if then trigger key-press event of simulation, otherwise, continue to detect.
Owing to adopt the mode of ejection soft keyboard, therefore, can adopt the dummy keyboard input and not adopt the physical keyboard input, can save physical button, provide cost savings.These several buttons of Menu, Back and Home like prior art Android equipment all are made in above the equipment with physical button; So just increase Material Cost, and after adopting scheme of the present invention, import through ejecting soft keyboard; Can save above-mentioned three physical button, provide cost savings.
See also Fig. 2.The present invention also provides a kind of Android equipment to comprise physical button, physical button detection module and the Android system end that connects successively.Wherein:
Physical button is used to supply the user to operate.
The physical button detection module is mainly used in signal and the sampling that receives physical button.In this specific embodiment, the physical button detection module is MCU, and it sends sampled signal through UART to the Android system end.
When physical button was pressed, the physical button detection module just received a signal, and sent after signal adopted.
The Android system end is mainly used in and receives said sampled signal and demonstrate soft keyboard in the particular display area of LCD.
The present invention receives the signal and the sampling of physical button through utilizing Android equipment; The Android system end of Android equipment receives said sampled signal and demonstrates soft keyboard in the particular display area of LCD; Thereby abandoned traditional scheme that the I/O mouth comes directly to connect physical button and Android system end of passing through, can not receive the restriction of chip I/O mouth and the restriction of physical button quantity.Simultaneously, adopt the mode that ejects soft keyboard can save the quantity of physical button, practice thrift cost.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
