Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example one
Fig. 1 shows an implementation process of a method for adjusting volume according to an embodiment of the present invention, which includes steps S101 to S105, and is detailed as follows:
step S101, when the terminal equipment is started, starting a bootstrap program in the terminal equipment.
In the embodiment of the invention, when a terminal device is started, a bootstrap program is started immediately. It is understood that in the art, the boot program refers to a segment of program that is executed by the terminal device after being powered on and before the kernel of the operating system is executed, and the boot program is the first and indispensable program to be executed in the embedded system. The bootstrap program is used for initializing the terminal equipment and establishing a memory space mapping relation, so that the terminal equipment is facilitated to call a kernel of an operating system, and finally various functional interfaces can be normally started.
Optionally, the bootstrap program includes: a Universal Boot Loader (U-Boot). U-Boot is a bootstrap program that follows the General Public License (GPL) open source code. The goal of the U-Boot is to support as many embedded processors and operating systems as possible to reduce the difficulty and effort of developers to develop Boot programs for embedded systems. U-Boot is a multi-stage Boot program, and the Boot flow is divided into two stages. Starting the U-Boot when the terminal equipment is started, firstly starting to execute a first phase of the U-Boot, and in the first phase, the U-Boot configures and initializes the necessary resources in the terminal equipment; and the second stage of the U-Boot is mainly used for finishing initialization work of development board hardware such as reading environment variables, initializing a memory, initializing a console and the like. After all initialization work is completed correctly, the U-Boot can also automatically execute predefined operation.
And step S102, loading a sound card driver and an interrupt processing program through the bootstrap program.
In the embodiment of the invention, the sound card driver and the interrupt processing program are loaded when the bootstrap program runs, namely before the operating system kernel runs.
It is understood that the sound card driver is used in the terminal device to adjust the volume of the device according to the operation instruction of the user.
It is understood that, in the art, an interrupt handler is a program that must be used when the terminal device and the external device perform data interaction in an interrupt manner. Specifically, the interrupt handler of the terminal device is configured to analyze an interrupt request of the external device to determine which external device the interrupt request is specifically initiated by, and determine which function is specifically requested by the interrupt request. Since the data interaction by the interrupt method is the prior art in the field, the principle of data interaction by the interrupt method will not be described herein.
Notably, the interrupt handler and the sound card driver have been previously added within the native device in which the boot program is located.
Optionally, the sound card driver and the interrupt handler are added to the board/TQ210 directory of the U-Boot file in advance, and then the sound card driver and the interrupt handler can be loaded after the U-Boot is started.
In the embodiment of the invention, the interrupt processing program and the sound card driving program are added in the file where the bootstrap program is located in advance, so that the interrupt processing program and the sound card driving program can be loaded after the bootstrap program is started, and therefore, the interrupt device can directly use the sound card driving program and the interrupt processing program through the bootstrap program without waiting for other functional interfaces to be started.
And S103, judging whether an operation instruction of a volume key is received by using the interrupt processing program.
In the embodiment of the present invention, the interrupt handler may parse an interrupt request sent by the external device, and after determining which interrupt source the interrupt request is initiated by, may determine a purpose of the interrupt request.
As an embodiment of the present invention, fig. 2 shows a specific implementation flow of the volume adjusting method S103 provided by the embodiment of the present invention, which is detailed as follows:
step S1031, when receiving an interrupt request, determines an interrupt source that issues the interrupt request by the interrupt handler.
In this embodiment of the present invention, the external device that initiates the interrupt request is the interrupt source in this embodiment of the present invention. For example, a remote control may be used as an interrupt source in embodiments of the present invention.
It is understood that the interrupt handler of the terminal device may recognize which interrupt source issued the interrupt request after receiving the interrupt request.
Further, if the interrupt request is received, a flag bit is set to indicate that the interrupt handler is being used.
It will be appreciated that when the interrupt handler is being used, another interrupt request can no longer be received and processed.
Step S1032, the data of the interrupt source in the interrupt state register is read, and whether the interrupt request is used for requesting the volume key interruption or not is judged according to the data of the interrupt source.
In the embodiment of the present invention, the interrupt status register of the interrupt device stores data of each interrupt source to which an interrupt request can be sent, and the data of each interrupt source includes a correspondence relationship between an interrupt function and interrupt request data. Therefore, after the interrupt source is determined, whether the interrupt request is used for requesting the volume key interrupt can be judged according to the corresponding relation between the interrupt function in the interrupt state register and the interrupt request data.
It is to be understood that, in the embodiment of the present invention, the volume key interrupt is a step necessary for volume adjustment, so that the volume adjustment must be performed after an interrupt request for requesting the volume key interrupt is recognized.
Step S1033, if the interrupt request is for requesting the volume key to interrupt, determining that an operation instruction of the volume key is received.
In step S1034, if the interrupt request is not for requesting the interrupt of the volume key, it is determined that the operation instruction of the volume key is not received.
In the embodiment of the invention, the interrupt function corresponding to the received interrupt request is judged through the data of each interrupt source stored in the interrupt state register, and then whether the terminal equipment receives the operation instruction of the volume key is judged so as to trigger the subsequent volume adjustment.
And S104, if the operation instruction of the volume key is received, analyzing the operation instruction of the volume key through a sound card driving function in the sound card driving program, and adjusting the volume of the terminal equipment.
It is to be understood that, as described in the above embodiment, if the terminal device receives an interrupt request, and the interrupt request is for requesting the volume key to be interrupted, the interrupt request necessarily includes an operation instruction of the volume key.
In the embodiment of the present invention, the sound card driver includes a sound card driver function, and the sound card driver function may be configured to analyze an operation instruction of the volume button, and adjust the volume of the terminal device according to the operation instruction of the volume button.
And S105, if the operation instruction of the volume key is received, ending the volume adjustment operation.
In the embodiment of the invention, when the terminal equipment is started, the bootstrap program in the terminal equipment is started, the sound card driving program and the interrupt processing program which are added into the local part where the bootstrap program is located in advance are loaded through the bootstrap program, the interrupt processing program is used for judging whether the operation instruction of the volume button is received, if the operation instruction of the volume button is received, the operation instruction of the volume button is analyzed through the sound card driving program, and the volume of the terminal equipment is adjusted, so that the terminal equipment can adjust the volume without an interface for a volume adjusting function, and the aim of adjusting the volume of a multimedia file at the starting stage of the terminal equipment is fulfilled.
