How to use other electronic devices to realize the design of resistive touch screen?
Touch screens are increasingly used in various fields of national production to realize handwriting input,
query, control, etc. These touch screens are mostly installed on monitors (CRT) or liquid crystals (LCD), and
there are more and more types of touch screens. There are vector pressure sensing technology touch screens,
resistive technology touch screens, capacitive technology touch screens, infrared technology touch screens, surface
acoustic wave technology touch screens, etc. Each of these touch screens has its own advantages and disadvantages.
There are many articles on them, so I will not go into details here. This article mainly introduces the correction principle,
algorithm and programming application design of the resistive technology touch screen installed on the LCD.

2.1 Overview

As we all know, touch screens based on resistive technology are divided into four-wire resistive touch screens, five-wire
resistive touch screens or more-wire resistive touch screens. However, no matter which type of resistive touch screen, there
is one biggest commonality:
the voltage is linearly and uniformly distributed. It is precisely because of this feature that the touch screen is very convenient to
calibrate and use. Speaking of touch screen calibration, some people may ask why the touch screen needs to be calibrated? We
know that the performance of the touch screen itself will be somewhat different, and the position will inevitably deviate when
installed on the LCD or CRT. In addition, after using it for a period of time, The performance parameters of the touch screen may
also change. Therefore, when we use different touch screens, it is difficult to guarantee that we will get the same touch coordinates
even if we touch the same position on the display screen. This makes it difficult for programmers to use the same program to manage
and control the touch screen. It is for this reason that we introduced the concept of calibration so that programmers using touch screen
devices can use a unified procedure to manage the touch screen.

2.2 Five-point method to calibrate touch screen

2.2.1 Physical coordinates and logical coordinates

In order to facilitate understanding, we first introduce two concepts, coordinates and logical coordinates. The physical coordinates are the
actual positions of the points on the touch screen, which we usually measure by the number of points on the liquid crystal.
Logical coordinates are the coordinate values ​​after A/D conversion when this point on the touch screen is touched. As shown
in the figure below, we assume that the lower
left corner of the liquid crystal is the origin of the coordinate axis A. We pick another point B on the liquid crystal (the center of the
cross line intersection). B is 10 points away from A in the X direction and 20 points away from A in the Y direction. Then
Let”s just say that the physical coordinates of this point on the touch screen opposite point B on the liquid crystal are (10, 20).
If the X-to-A/D conversion value we get when we touch this point is 100, and the Y-to-A/D conversion value is 200, we say that the logical coordinates of this point are (100, 200).

2.2.2 Calculation of logical coordinates

Since the voltage of the resistive touch screen is linearly and uniformly distributed, the coordinates after A/D conversion are also
linear. If we set the point on the touch screen corresponding to the lower left corner of the liquid crystal as the physical coordinate
origin A, its physical coordinates are marked as (XA=0, YA=0) and its logical coordinates are marked as (XLA, YLA) (not necessarily 0).
Then the logical coordinates of any point B on the touch screen can be expressed as:
