| description | As one of the mainstream ways of human-computer interaction, touch screens have very important research value. One of the important directions is the development of self-capacitive touch screens. However, the current self-capacitive touch screen data acquisition circuit has only 13 capacitive channels at most, which severely limits the expansion of the number of touch points in the development of self-capacitive touch screens. In view of the problem of the small number of capacitive channels in the touch screen data acquisition circuit , a touch screen data acquisition system controlled by Arduino is designed, including hardware and software. The hardware part is a touch detection circuit, which can detect up to 24 capacitance channels, and the software part is a graphical interface. It can detect the working status of the touch point of the self-capacitive touch screen in real time，and dynamically display the working status of touch points in the form of graphical interface. |
