Embodiment 1

[0025] figure 1 It is an implementation flowchart of the touch screen firmware upgrade method provided by the embodiment of the present invention, and is described in detail as follows:

[0026] In step S101, obtain the firmware version number stored in the touch screen register;

[0027] Wherein, the touch screen driver in the mobile terminal, the IIC read and write function reads the touch screen firmware version number stored in the touch screen register.

[0028] The operating system running on the mobile terminal includes but not limited to Windows Phone operating system, Android operating system, and ios operating system, and the preferred operating system is based on Windows phone 8.1 operating system.

[0029] Wherein, the touch screen register includes the register of the capacitive touch screen and the touch screen of the inductive touch screen.

[0030] In step S102, compare the new firmware version number with the size of the firmware version number stored in the...

Embodiment 2

[0039] figure 2 It is an implementation process diagram of step S101 of the touch screen firmware upgrade method provided by the embodiment of the present invention, and is described in detail as follows:

[0040] In step S201, initialize the driver program of the touch screen, and obtain two IIC address information configured by the touch screen in ACPI;

[0041] Wherein, open mobile terminal, load the driver program of touch screen, initialize driver program, obtain two IIC address information of ACPI (Advanced Configuration and Power Management Interface, advanced configuration and power management interface) configuration touch screen, when updating described touch screen firmware, control reset pin current The level is high level or low level, and the corresponding instruction is written according to the IIC writing function to obtain the current firmware version number of the touch screen.

[0042] In step S202, randomly assign two IIC address information to the IIC re...

Embodiment 3

[0050] image 3 It is a diagram of the implementation process before step S101 provided by the embodiment of the present invention, and is described in detail as follows:

[0051] In step S301, create a GPIO target to connect the touch screen with the central processing unit;

[0052] Among them, create a GPIO target to complete the information transmission channel between the touch screen and the central processing unit.

[0053] In step S302, the GPIO target is initialized, and the current level of the reset pin of the GPIO of the touch screen is controlled to be a high level or a low level.

[0054] Among them, by initializing the GPIO (General Purpose Input Output, general purpose input / output, mainly connected to the central processing unit and touch screen IC) target, using the read and write function of GPIO, when it is necessary to control the reset pin of GPIO to be high, call the read and write function of GPIO Write 1; when it is necessary to control the reset pin...

Abstract

The invention is applicable to the technical field of touch control, and provides a touch screen firmware upgrading method and device. The method comprises the following steps of acquiring a firmware version number stored in a touch screen register; comparing the sizes of a new firmware version number and the firmware version number stored in the register; and calling inter-integrated circuit (IIC) reading-writing data when the size of the new firmware version number is greater than the size of the firmware version number stored in the register, and updating the firmware version number stored in the register. ICC address information corresponding to the ICC reading-writing data is adjusted in real time according to the ICC reading-writing function of a touch screen, corresponding data is read, the current version number of the touch screen is acquired, and the purpose of updating the version is achieved by comparing the sizes of the version numbers; the problem that the data corresponding to the ICC address information cannot be read to cause the touch screen firmware not to be updated on the condition of information of two ICC addresses is solved; the touch screen firmware can be enabled to be updated in no needed of disassembling the touch screen again; the touch screen is prevented from being disassembled, and the firmware is prevented from being burned; and moreover, the production management efficiency of the touch screen is also improved.

Description

technical field [0001] The invention belongs to the field of touch technology, and in particular relates to a touch screen firmware upgrade method and device. Background technique [0002] With the development of touch technology and terminal technology, more and more terminal devices use touch mode for human-computer interaction. At present, during the production process of touch screens, manufacturers usually use their own software and tools to program firmware into touch screen ICs (Inter-Integrated, integrated circuits), and package the touch screen ICs at the same time. When it is necessary to update the functions and data of the touch screen firmware, the touch screen has been packaged or installed on the mobile terminal, which blocks the upgrade of the touch screen firmware. [0003] However, the existing methods for updating touch screen firmware cannot guarantee that the touch screen firmware can be successfully updated without disassembling the mobile terminal or ...
