The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1, fig. 1 is a loading method, a storage medium and a terminal device for a touch screen driver according to the present invention. The method comprises the following steps:
and S100, when the driver program entry function is called, sequentially loading the touch screen driver program entry function program.
Specifically, the terminal device generally only supports one touch screen interface but can be compatible with touch screens of various types, and the touch screen driver can communicate with the touch screen hardware and usually needs to know which IIC bus the touch screen hardware is hung on in the system and the terminal address of the touch screen hardware.
In an implementation manner of this embodiment, first, a driver of a touch screen of a terminal device is modified in advance to a boot loading form. Therefore, when the terminal equipment is started, the entry function of the touch screen driving program can be modified so as to search and enumerate the IIC bus of the system, namely, the driving program corresponding to the touch screen equipped by the current terminal equipment is searched.
Correspondingly, in an implementation manner of this embodiment, the method for loading the touch screen driver further includes:
and S10, storing all touch screen drivers compatible with the mobile terminal in advance, and compiling in the driver entry function of the touch screen.
Specifically, the invention compiles all drivers compatible with the terminal equipment into a module form or directly into an operating system kernel in advance, and then adds all the drivers into a boot loading sequence. That is to say, in this embodiment, the IIC bus may be enumerated in the driver entry function of the terminal device in advance, and the touch screen device corresponding to the driver may be established on the corresponding bus to establish the mapping relationship.
In an implementation manner of this embodiment, after the connection relationship is established, it is to be determined whether the terminal device and the touch screen are correctly connected, and correspondingly, when the entry function of the driver is called, sequentially loading the driver of the entry function terminal specifically includes:
and S101, when the driver program entry function is called, judging the connection state of the terminal equipment and the touch screen.
And S102, when the connection is correct, sequentially loading the programs of the driver entry functions of the terminal.
Specifically, the method and the device judge the connection state of the terminal device and the touch screen when the driver program entry function is called, and sequentially load the programs of the driver program entry function of the touch screen when the connection is correct. Correspondingly, the judging the connection state of the terminal device and the touch screen specifically comprises:
s1011, sending the address information of the touch screen to the touch screen;
s1012, when the terminal equipment receives the data packet fed back by the touch screen, judging that the connection between the touch screen and the terminal equipment is correct;
and S1013, when the terminal equipment does not receive the data packet fed back by the touch screen, judging that the connection between the touch screen and the terminal equipment is wrong.
Specifically, the invention needs to send the address information of the touch screen to the IIC touch screen and determine whether the connection relationship is correct through the device response (ACK), and once the terminal device receives the ACK response signal of the touch screen response, which indicates that the mapping of the connection relationship between the hardware connection and the current software is correct, the drive of the touch screen can be continuously loaded, so that the touch screen can be normally used. It can be understood that when the terminal device does not receive the response of the touch screen, the touch screen is connected incorrectly, and the driver does not need to be loaded any more, and the terminal device can directly exit.
And S200, when the driver which is successfully loaded exists, taking the driver which is successfully loaded as the driver of the terminal equipment.
Specifically, the present invention sequentially loads the touch screen drive entry function programs of the terminal, and when a certain driver can be normally loaded, the touch screen currently connected to the hardware can normally operate, and accordingly, in an implementation manner of this embodiment, when there is a driver that is successfully loaded, taking the successful driver as the driver of the terminal device specifically includes:
s201, when the loading of the previous driver fails, continuing to load the subsequent driver;
s202, when the driver which is loaded successfully exists, the driver which is loaded successfully is used as the driver of the terminal equipment.
Specifically, after the previous driver fails to be loaded, the system continues to load the subsequent drivers, and the subsequent drivers can be implemented through the steps, and when the successfully loaded driver exists, the successfully loaded driver is used as the driver of the terminal device, that is, when one of the drivers can be loaded normally, the touch screen connected to the current hardware can work normally.
In an implementation manner of this embodiment, the method for loading a touch screen driver further includes:
and S203, when all the drivers fail to be loaded, the driver matched with the terminal equipment is not found.
Specifically, after one driver is loaded, the terminal hardware can only be connected with one touch screen, so that loading of other drivers fails to ensure that only the touch European style corresponding to the hardware can be loaded and normally used.
In the embodiment, the compatible operation is performed on the touch screen with the compatible model, so that software modification and software upgrading caused by replacing different models of touch screens are avoided, further, related information does not need to be added in the device tree or the platform device file in advance, only enumeration of the IIC bus and device enumeration operation need to be added in the driving program, and therefore development cost and maintenance cost are reduced.
The present invention also provides a computer-readable storage medium storing one or more programs, which are executable by one or more processors to implement the steps in the loading method of a touch screen driver described in the above embodiments.
The present invention also provides a terminal device, as shown in fig. 3, which includes at least one processor (processor) 20; a display screen 21; and a memory (memory)22, and may further include a communication Interface (Communications Interface)23 and a bus 24. The processor 20, the display 21, the memory 22 and the communication interface 23 can communicate with each other through the bus 24. The display screen 21 is configured to display a user guidance interface preset in the initial setting mode. The communication interface 23 may transmit information. The processor 20 may call logic instructions in the memory 22 to perform the methods in the embodiments described above.
Furthermore, the logic instructions in the memory 22 may be implemented in software functional units and stored in a computer readable storage medium when sold or used as a stand-alone product.
The memory 22, which is a computer-readable storage medium, may be configured to store a software program, a computer-executable program, such as program instructions or modules corresponding to the methods in the embodiments of the present disclosure. The processor 30 executes the functional application and data processing, i.e. implements the method in the above-described embodiments, by executing the software program, instructions or modules stored in the memory 22.
The memory 22 may include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function; the storage data area may store data created according to the use of the terminal device, and the like. Further, the memory 22 may include a high speed random access memory and may also include a non-volatile memory. For example, a variety of media that can store program codes, such as a usb disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk, or an optical disk, may also be transient storage media.
