There is capacitance variation in step S102, the touching of the capacitive sensing finger in the capacitance matrix；
Step S103, the MCU find out according to the corresponding relation set up in the change and step S101 and are sent out with capacitance
The corresponding LED in the position of the electric capacity of changing, and accordingly generate lightening LED lamp light instruction；It is described to light instruction bag
Include：
The instruction that the LED of correspondence position is lighted；
And specify the instruction for lighting brightness；
In other optional embodiments of the invention, the finger that the LED on correspondence position LED periphery is lighted is may also include
Order.Described lighting instructs the brightness of lighting of the LED for being also possible that correspondence position to be more than the brightness that the LED on periphery is lighted,
And the LED on periphery is lighted increase that brightness is spaced with it and the LED of the correspondence position between and is reduced；Here institute
Claim the increase at interval, can be the increase of the distance distance of the quantity increase, or interval of the LED at interval.
Further, in an optional embodiment of the invention, the LED on the LED periphery of correspondence position is described right
The LED for answering the LED of position adjacent.Further, the brightness of adjacent LED is the LED brightness of the correspondence position
Half；
Specifically lighting logic can be programmed confirmation in advance.
Step S104, the LED is lighted instruction realization and is lighted according to this；
With reference to Fig. 1, the present embodiment is put up with " described to light the instruction that only LED including correspondence position is lighted in instruction；”
Process describe in detail, when finger touch somewhither as (X0, Y0) when, MCU 2 gets corresponding touch position information,
And the corresponding first position information of closest LED is found for two-dimensional coordinate (0,11)；Then, MCU 2 sends and lights
To system end 3, light instruction and carry first position information i.e. two-dimensional coordinate (0,11) and corresponding first monochrome information.Here
The first monochrome information can be represented with brightness percentage, 100% represent brightness highest, 0% represent brightness it is minimum, can basis
It is actually needed and is preset, it is assumed herein that the first monochrome information is 100%.System end 3 is received after lighting instruction, can be according to the
One positional information and the first monochrome information light the LED of corresponding position (0,11), and brightness is 100%.Similarly, finger is worked as
When touching (X1, Y1), MCU 2 gets corresponding touch position information, and finds corresponding LED, its can be away from
From nearest LED, determine according to the corresponding relation for having set in a word, corresponding first position information be two-dimensional coordinate (0,
10)；Then, MCU 2 sends and lights instruction to system end 3, lights instruction and carries first position information i.e. two-dimensional coordinate (0,10)
And corresponding first monochrome information；System end 3 is received after lighting instruction, can be according to first position information and the first brightness
The LED of the bright corresponding position of information point (0,10), brightness is 100%.
Embodiment 2
The present embodiment is differred primarily in that with embodiment：It is described light instruction in except the LED including correspondence position
The instruction lighted；Instruction and confirm its instruction for lighting brightness that also the LED including correspondence position LED periphery is lighted.Institute
State and light the brightness lighted of LED that brightness is more than periphery of lighting that instruction also causes the LED of correspondence position, and periphery
LED is lighted increase that brightness is spaced with it and the LED of the correspondence position between and is reduced；
Further, in an optional embodiment of the invention, the LED on the LED periphery of correspondence position is described right
The LED for answering the LED of position adjacent.Further, the brightness of adjacent LED is the LED brightness of the correspondence position
Half；
So, while realizing touching feedback display function, the control of light and shade gradual change, energy are done in the also brightness to LED
Enough illumination effects for realizing similar meteor.
Still the example with reference to shown in Fig. 1 is specifically described, and it reflects a kind of specific programming design, works as finger
When touching (X1, Y1), MCU 2 gets corresponding touch position information, and finds closest LED corresponding
One positional information is two-dimensional coordinate (0,10), and sets corresponding monochrome information (100%)；Again by the two-dimensional coordinate (0,10) with
And corresponding monochrome information (100%) is stored in default LED data sets to be lighted.Search adjacent with initial LED (0,10)
The corresponding positional information of two LEDs, respectively (0,9) and (0,11)；And corresponding monochrome information is set, it is 50%；Again
Two-dimensional coordinate (0,9) and (0,11) and corresponding monochrome information (50%) are stored in LED data sets to be lighted.Then, MCU 2
Instruction to system end 3 is lighted in transmission, lights the data that instruction carries the storage in LED data sets to be lighted.System end is received
Instruction is lighted, according to the data in LED data sets to be lighted, while the LED at (0,9), (0,10) and (0,11) place is lighted,
Brightness is respectively 50%, 100% and 50%.I.e. LED of finger touch place etc. is most bright, and the LED of adjacent is also lighted, but bright
Degree takes second place.
Above is two kinds of realizations of brightness step, will describe a kind of realization of three kinds of brightness steps, it should be appreciated that dawn, nothing below
There are several settings by the gradient of brightness, be all one of scheme that the present invention makes every effort to protection,
Still the example with reference to shown in Fig. 1 is specifically described, and when finger touches (X1, Y1), MCU2 gets phase
The touch position information answered, and the corresponding first position information of closest LED is found for two-dimensional coordinate (0,10), and
Corresponding monochrome information (100%) is set；The two-dimensional coordinate (0,10) and corresponding monochrome information (100%) are stored in again pre-
If LED data sets to be lighted.The two LEDs corresponding positional information adjacent with initial LED (0,10) is searched, respectively
And (0,11) (0,9)；And corresponding monochrome information is set, it is 50%；Again by two-dimensional coordinate (0,9) and (0,11) and correspondence
Monochrome information (50%) be stored in LED data sets to be lighted.Then, then search adjacent with (0,9) and (0,11) two, place LED
The corresponding positional information of LED, respectively (0,8) and (0,12)；And corresponding monochrome information is set, it is 25%；Again will
Two-dimensional coordinate (0,8) and (0,12) and corresponding monochrome information (25%) are stored in LED data sets to be lighted.The sending points of MCU 2
Bright instruction lights the data that instruction carries the storage in LED data sets to be lighted to system end 3.System end is received lights finger
Order, according to the data in LED data sets to be lighted, while lighting (0,8), (0,9), (0,10), (0,11) and (0,12) place
LED, brightness is respectively 25%, 50%, 100%, 50% and 25%.That is the LED of finger touch place is most bright；Adjacent
LED also light, but brightness is taken second place；LED adjacent thereto is also lighted again, but brightness is more taken second place.
