Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
The problem existed for prior art, embodiments provides touch chip under a kind of COB technique
Burning program method, the method is to be pre-configured with on touch screen module to be connected with mainboard by producers
The level of terminal, and respective pins in interface to be connected with touch screen module on mainboard is set to high electricity
Flat, after touch screen module is connected to mainboard, by judging the interface being connected on mainboard with touch screen module
The level state of middle respective pins, identifies touch screen module manufacturer, and then calls the corresponding touch-control journey prestored
Sequence is also burnt in touch chip.
Fig. 3 shows the stream of the burning program method of touch chip under the COB technique that the embodiment of the present invention provides
Journey, comprises the following steps:
Step S101: by the mainboard of touch screen terminal, corresponding in the interface to be connected to touch screen module draws
Foot is set to high level, and configures the level of terminal to be connected with mainboard on touch screen module.Therein tactile
Touch screen terminal and refer to the terminal unit with touch screen module, the most various there is touch screen module mobile phone,
Computer etc.；Interface to be connected therein can be carry on the mainboard of existing touch screen terminal interface (such as:
GPIO interface etc.), it is also possible to it is the interface suitably newly-increased regarding demand.
In the embodiment of the present invention, the end that the quantity of interface to be connected on mainboard is to be connected with on touch screen module
The quantity of son is equal, and the difference of the quantity of the touch screen module manufacturer identified as required, the company for the treatment of on mainboard
The quantity of terminal to be connected in the quantity of the interface connect and touch screen module is the most different.Assume to treat on mainboard
Connect interface quantity be n(n be positive integer), then the quantity of terminal to be connected on touch screen module is n,
Quantity N of discernible touch screen module manufacturer meets: N=2n。
As an example it is assumed that interface to be connected on mainboard is 2, then end to be connected on touch screen module
The quantity of son is 2, and discernible touch screen module manufacturer is 4.In step S101, by mainboard
2 interfaces to be connected in the respective pins that is connected with touch screen module be set to high level, configure simultaneously
The level of 2 terminals to be connected on touch screen module so that 4 different touch screen module manufacturers touch
Touch on screen module, the level of 2 terminals to be connected is respectively as follows: low level and low level, low level and height
Level, high level and low level, high level and high level.In actual design, can be by by be connected
Terminal ground, it is achieved the low level configuration of terminal.
Step S102: after terminal to be connected connects with corresponding interface to be connected, on identification mainboard,
The level state of respective pins in the interface being connected with touch screen module, thus distinguish touch screen module manufacturer.
Step S103: according to recognition result, calls the touch control procedure of the corresponding touch screen module manufacturer prestored.
Before step S103, the embodiment of the present invention is further comprising the steps of: according to the input of user, sets up
Associated data structures also stores.This associated data structures characterizes the level of respective pins in interface to be connected
