Referring to fig. 1, fig. 1 is a schematic diagram of a touch screen driver loading method, a storage medium and a terminal device according to the present invention. The method comprises the following steps:
s100, when the entry function of the driver is called, the entry function programs of the touch screen driver are loaded in sequence.
Specifically, the terminal device generally only supports one touch screen interface and can be compatible with touch screens of various types, the touch screen driver needs to know which IIC bus in the system the touch screen hardware is hung on and the terminal address of the touch screen hardware, and the terminal device can support the touch screens of various types simultaneously by modifying the driver program, so that modification of software and upgrading of the terminal device are avoided, and development cost and maintenance cost are reduced.
In one implementation manner of this embodiment, first, a driver of a touch screen of a terminal device is modified into a form of boot loading in advance. Therefore, when the terminal equipment is started, the entry function of the touch screen driver program can be modified so that the IIC bus of the system can be searched and enumerated, namely, the driver program corresponding to the touch screen equipped by the current terminal equipment is searched.
Correspondingly, in one implementation manner of this embodiment, the method for loading a touch screen driver further includes:
s10, storing all touch screen drivers compatible with the mobile terminal in advance, and compiling the touch screen drivers in a driver entry function of the touch screen.
Specifically, the invention compiles the drivers compatible with the terminal equipment into a module form in advance or directly compiles the drivers into an operating system kernel, and then adds the drivers into a startup loading sequence. That is, in this embodiment, the IIC bus may be enumerated in advance in the driver entry function of the terminal device, and the mapping relationship may be established by establishing the touch screen device corresponding to the driver on the corresponding bus.
In one implementation manner of this embodiment, after the connection relationship is established, whether the terminal device and the touch screen are correctly connected is further determined, and correspondingly, when the entry function of the driver is called, loading the driver of the entry function terminal in sequence specifically includes:
s101, judging the connection state of the terminal equipment and the touch screen when the entry function of the driver program is called.
S102, when the connection is correct, sequentially loading programs of the driver entry functions of the terminal.
Specifically, when the driver entry function is called, the invention judges the connection state of the terminal equipment and the touch screen, and when the connection is correct, the invention loads the programs of the driver entry function of the touch screen in sequence. Correspondingly, the judging the connection state of the terminal equipment and the touch screen specifically comprises the following steps:
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 touch screen is correctly connected with the terminal equipment;
s1013, when the terminal equipment does not receive the data packet fed back by the touch screen, judging that the touch screen is connected with the terminal equipment in error.
Specifically, the invention needs to determine whether the connection relation is correct by sending the address information of the touch screen to the IIC touch screen and by means of equipment response (ACK), and once the terminal equipment receives an ACK response signal of the touch screen response, the mapping of the hardware connection and the current software connection relation is indicated to be opposite, and the driving 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 with the terminal device in error, that is, the driver is not required to be loaded any more, and the terminal device can be directly exited.
And S200, when the successfully loaded driver exists, taking the successfully loaded driver as a driver of the terminal equipment.
Specifically, the method and the device for loading the touch screen drive entry function program of the terminal sequentially load the touch screen drive entry function program of the terminal, when a certain driver can be normally loaded, the touch screen connected with the current hardware can work normally, and correspondingly, in one implementation manner of the embodiment, when a successfully loaded driver exists, the successfully loaded driver is taken as the driver of the terminal device, and the method and the device specifically comprise the following steps:
s201, when the last driver fails to load, continuing to load the subsequent drivers;
s202, when a successfully loaded driver exists, the successfully loaded driver is used as a driver of the terminal equipment.
Specifically, when the last driver fails to load, the system continues to load the subsequent drivers, and when there is a driver that is successfully loaded, the driver that is successfully loaded is used as the driver of the terminal device, that is, when one of the drivers can be normally loaded, the touch screen connected with the current hardware can normally work.
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 drivers matched with the terminal equipment are not found.
Specifically, when one driver is loaded, since the terminal hardware can only be connected with one touch screen, other drivers can fail to be loaded, so that only the touch screen corresponding to the hardware can be loaded and used normally.
In this embodiment, by performing compatible operation on touch screens with compatible models, software modification and software upgrading caused by replacing touch screens with different models are avoided, and further, related information does not need to be added in advance in a device tree or a platform device file, and only enumeration of an IIC bus and operation of device enumeration need to be added in a driver, so that development cost and maintenance cost are reduced.
The present invention also provides a computer readable storage medium storing one or more programs executable by one or more processors to implement the steps in the method for loading a touch screen driver described in the above embodiments.
The present invention also provides a terminal device, as shown in fig. 3, comprising at least one processor (processor) 20; a display screen 21; and a memory (memory) 22, which may also include a communication interface (Communications Interface) 23 and a bus 24.
