Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an embodiment, as shown in fig. 1, a touch data conversion method is provided, which specifically includes the following steps:
and S10, detecting the original data format of the input touch signal, acquiring a detection result, and analyzing the original data format corresponding to the touch signal into a general data format based on the detection result and a corresponding protocol analysis algorithm.
Specifically, the touch screen is used for sensing the touch of a finger, and when the finger touches a specific position on the screen, an accurate electronic signal is transmitted to the screen. The principle of the touch screen is that when a finger or other foreign objects contact the touch screen, two conductive layers which are originally isolated from each other form contact at the position of a touch point, the resistance changes, the corresponding voltage value also changes, touch signals in X and Y directions are generated, and the touch signals are converted into digital pulse signals through analog/digital (A/D) and then transmitted to a control machine (host) for processing.
Different modules or modules generate communication signals with different communication data formats, most of the communication signals are I2C and SPI (Serial Peripheral Interface), in order to quickly identify touch signals generated by different manufacturers, a protocol analysis algorithm can be adopted, the algorithm records the formats of the touch signals into a format recording table based on different manufacturers in advance, and each input touch signal is matched with the format recording table so as to match the manufacturers. And the corresponding signal analysis algorithm can be obtained according to the matched production merchants, so that the touch signals with different input formats can be unified into a universal data format.
The touch data conversion device provided by the embodiment comprises a plurality of hardware bus input interfaces, such as a bus I2C, or data input interfaces with different SPIs, such as data input interfaces with voltages of 1.8V, 3.3V, and the like.
In this embodiment, the generic data format may be set to the original coordinate + event format. The original coordinates are coordinates of the touch signal, and the event is all data related to the coordinates, such as resolution of the coordinates, sum of channels (original pixel number) on rows and columns, and touch value, and the like. Further, after detecting the corresponding touch IC manufacturer, the system may invoke an embedded algorithm to parse into a fixed generic data format, including but not limited to the following:
1. coordinate X, 2 BYTE type data;
2. coordinate Y, 2 BYTE type data;
3. event, 1 BYTE type data.
Preferably, the method for detecting the original data format of the input touch signal and obtaining the detection result specifically includes the following steps:
and detecting at least one of a frame length, frame data, a frame check position, a characteristic character in the frame or a frame data convolution characteristic corresponding to any frame in the touch signals, and acquiring the type of the touch module as a detection result.
Specifically, the present embodiment can be used for matching the touch signal to obtain the touch module type (factory format of the manufacturer) to perform the following detection methods including, but not limited to:
1. a frame length;
2. frame header data;
3. frame tail data;
4. checking the position of the frame in the current frame;
5. fixed characteristic characters or data in the frame, which can identify a certain touch IC manufacturer;
6. the convolution value characteristics of all data of the frame, and the like.
And S20, converting the general data format into Sudoku touch difference data with a complete channel for calculating coordinates by adopting a format conversion algorithm.
Specifically, a full channel means that the squared difference touch data includes channels (original pixel numbers) on rows and columns. The present embodiment may employ a control unit having a data matching algorithm, such as an STM32MCU, to implement data conversion.
The nine-square grid touch difference data is data used by the host computer to calculate and obtain final touch coordinates. In the embodiment, the unified original coordinate + event data format is converted into squared touch difference data corresponding to the gravity center of the original coordinate. When calculating the gravity center, taking P (r, c) as the center, wherein r, c is the channel position of the row and the column of the center position, and taking the data in the range of 1 row/1 column (Sudoku) to participate in the calculation.
The coordinates and the gravity center are corresponding, taking the nine-square grid as shown in FIG. 2 as an example, P (r, c) is expanded by 1 row and 1 column, and the channel position (r, c) of X2/Y2; the size represents the number of original pixels defined for each channel (RX or TX direction), typically 64, and can also be calculated from the resolution and the number of channels in rows and columns, usually called TX and RX.
The coordinate value calculated by the above coordinate calculation formula is listed
Equation one:
X＝((x1_y1*(c-1))+(x1*(c-1))+(x1_y3*(c-1))+(y1*c)+(x2_y2*c)+(y3*c))+(x3_y1*(c+1))+(x3*(c+1))+(x3_y3*(c+1)))/(x1_y1+x1+x1_x3+y1+x2_y2+y3+x3_y1+x3+x3_y3)*X_Size+0.5*X_Size；
Y＝((x1_y1*(r-1))+(y1*(r-1))+(x3_y1*(r-1))+(x1*r)+(x2_y2*r)+(x3*r))+(x1_y3*(r+1))+(y3*(r+1))+(x3_y3*(r+1)))/(x1_y1+x1+x1_x3+y1+x2_y2+y3+x3_y1+x3+x3_y3)*Y_Size+0.5*Y_Size；
in particular, the following calculation may be used to obtain an approximation of the X, Y coordinates.
Equation two:
X＝((x1*(c-1))+(x2_y2*c)+(x3*(c+1))/(x1+x2_y2+x3)*X_Size+0.5*X_Size；
Y＝((y1*(r-1))+(x2_y2*r)+(y3*(r+1)))/(y1+x2_y2+y3)*Y_Size+0.5*Y_Size；
the following contents can be derived for the calculation relationship of the coordinates reported by the touch IC:
equation three:
Tx_Nums*X_Size＝X_Resulotion；
Rx_Nums*Y_Size＝Y_Resulotion；
wherein Tx _ Nums is the number of TX channels of the touch module ITO, and Rx _ Nums is the number of RX channels of the touch module ITO. X _ Resultion and Y _ Resultion are the maximum values of the X, Y reported values, typically the resolution of the display or touch area.
From equation three, equation four can be derived:
X_Size＝X_Resulotion/Tx_Nums；
Y_Size＝Y_Resulotion/Rx_Nums；
equation five can be derived from equation two and equation four:
X*Tx_Nums/X_Resulotion＝((x1*(c-1))+(x2_y2*c)+(x3*(c+1))/(x1+x2_y2+x3)+0.5；
Y*Rx_Nums/Y_Resulotion＝((y1*(r-1))+(x2_y2*r)+(y3*(r+1)))/(y1+x2_y2+y3)+0.5；
since the essence of the coordinate formula is to calculate the barycentric position of a finger touch for one area, i.e., to calculate the barycentric position in the X direction and the barycentric position in the Y direction, respectively, it can be assumed that the Sum of all touch quantities in the X direction is X _ Diff _ Sum and the Sum of all touch quantities in the Y direction is Y _ Diff _ Sum.
Then there is equation six:
X_Diff_Sum＝x1+x2_y2+x3；
Y_Diff_Sum＝y1+x2_y2+y3；
the values of X _ Diff _ Sum and Y _ Diff _ Sum for a normal touch can each take on the order of 3000. That is, X _ Diff _ Sum — Y _ Diff _ Sum — 3000;
a particular value of Sum/2 may be taken for x2_ y2, i.e., x2_ y2 equals Sum/2;
equation seven can be obtained:
x1+x3＝Sum/2；
y1+y3＝Sum/2；
equation eight can be derived from equations six and seven:
X*Tx_Nums/X_resulotion＝((x1*(c-1))+(x2_y2*c)+(x3*(c+1))/(x1+x2_y2+x3)+0.5；
Y*Rx_Nums/Y_resulotion＝((y1*(r-1))+(x2_y2*r)+(y3*(r+1)))/(y1+x2_y2+y3)+0.5；
further optimization can result in equation nine:
X1＝(Sum/2)*(1-(X*Tx_Nums/(X_Resolution)-c))；
X3＝(Sum/2)*(X*Tx_Nums/(X_Resolution)-c)；
y1＝(Sum/2)*(1-(Y*Rx_Nums/(Y_Resolution)-r))；
y3＝(Sum/2)*(Y*Rx_Nums/(Y_Resolution)-r)；
wherein
c＝[X*Tx_Nums/(X_Resolution]
R＝[Y*Rx_Nums/(Y_Resolution]
In the above formula [ ] is a rounded symbol.
According to the method for taking the gravity center approximation, the data values of the coordinate points P (x1, y1), P (x3, y1), P (x1, y3) and P (x3, y3) on the screen can be respectively represented by the following equation ten:
x1_y1＝aver(x1,y1)；
X3_y1＝aver(x3,y1)；
X1_y3＝aver(x1,y3)；
X3_y3＝aver(x3,y3)；
where aver is the average.
One complete frame of squared touch difference data can be obtained by equations nine and ten.
And S30, acquiring a host corresponding to the touch signal by adopting a characteristic matching algorithm, outputting the touch difference data of the Sudoku to the host, and reversely obtaining touch coordinates by the host based on the touch difference data of the Sudoku.
Specifically, after the host computer which needs to read the touch difference data reads the squared figure touch difference data, a gravity center algorithm, namely a position where the finger touches a certain area is deviated to a certain direction, can be adopted to reversely calculate the touch coordinate.
Practical examples of S20-S30 are as follows:
if the number of channels touching the touch screen TP on the IC is 22x12, the original coordinates are provided as (500, 1000); sum of touch values is 3000; resolution X _ Resolution 1080 and Resolution Y _ Resolution 2340.
Then from the above it can be derived: the channel position of the finger touch is
C＝500*12/1080＝[5.555555555555555]＝5；
R＝1000*22/2340＝[9.401709401709402]＝9；
The following data can be obtained from equation nine:
X1＝(Sum/2)*(1-0.555555555555555)＝666.666；
X2＝(Sum/2)＝1500；
X3＝(Sum/2)*0.555555555555555＝833.333；
y1＝(Sum/2)*(1-0.401709401709402))＝897.435；
Y2＝(Sum/2)＝1500；
y3＝(Sum/2)*0.401709401709402＝602.564；
and combining equation ten to obtain nine-grid touch difference data, wherein the nine-grid touch difference data are obtained as shown in the following table:
| 782 | 897 | 890 |
| 667 | 1500 | 833 |
| 635 | 602 | 718 |
table one
The coordinate calculation process from the squared figure is reversed as follows:
since Tx1_ Nums is 12, X _ Resolution is 1080.
There is thus the following equation eleven:
X_Size＝1080/12＝90；
Y_Size＝2340/22＝106.363；
the coordinates can be calculated by substituting the touch difference data of the nine-square grids into a formula-gravity center algorithm:
X＝(4*782+4*667+4*635+897*5+1500*5+602*5+890*6+883*6+718*6)/(782+667+635+897+1500+602+890+883+718)*X_Size+0.5*X_Size＝5.053*90+90*0.5＝499.5；
Y＝(782*8+897*8+890*8+667*9+1500*9+833*9+635*10+602*10+718*10)/(782+667+635+897+1500+602+890+883+718)*Y_Size+0.5*Y_Size＝995.512；
because the coordinate error between the coordinate X calculated by the nine-grid touch difference data according to the gravity center algorithm and the input original X coordinate is only (500-499.5)/1000-0.0005, and the error of Y is (1000-995.512)/2340-0.0019, the error in actual use is lower, the calculation accuracy of decimal data is higher when the calculation is actually performed by using a continuous equation, and the error rate of the coordinate actually used in the actual measurement is not more than 0.001.
According to the touch data conversion method, the touch data conversion device, the computer equipment and the storage medium, the touch modules in different coordinate forms reported by the touch IC manufacturer are applied to various hosts reading the touch difference data architecture, so that the rapid introduction and switching of different touch IC modules, verification and mass production are greatly facilitated, the mass production period is effectively shortened, and the application of the touch IC modules to the hosts needing to read the touch differences is facilitated.

And S22, taking the position coordinates (r, c) of the central channel as a center, and acquiring the original data of the Sudoku corresponding to the Sudoku formed by all adjacent coordinates of a row and a column which are externally expanded around.
And S23, acquiring nine-square grid touch difference data corresponding to the gravity center corresponding to the original coordinate based on the original nine-square grid data.

In a specific embodiment, the host machine reversely obtains the touch coordinate through a gravity center algorithm based on the nine-square grid touch difference data, and specifically includes the following steps:
based on the Sudoku touch difference data, the touch coordinates are obtained by adopting the following formula in the gravity center algorithm:
X＝(ΣSumCOLm*m/ΣSumCOLm)*size+size*0.5。
Y＝(ΣSumROWn*n/ΣSumROWn)*size+size*0.5。
wherein, SumROWn represents the sum of touch values of each row, n represents a row number, sumcolom represents the sum of touch values of each column, m represents a column number, and size represents the original pixel number defined by each channel in the row direction or the column direction.
In a specific embodiment, the obtaining of the host corresponding to the touch signal by using the feature matching algorithm specifically includes the following steps:
and sending broadcast data to all controllers, and detecting at least one of frame length, frame data, frame check position, characteristic characters in the frame or frame data convolution characteristics corresponding to any frame in handshake data returned by each controller, so as to obtain the controller matched with the touch signal as a host.
