Title: Calibration of Resistive Touch-Screen Based on C8051
Abstract: The system is based on C8051F040 MCU.The circuit connection between four-wire resistive touch screen and MCU is introduced in detail,and the three-point method to calibrate the touch screen based on this hardware system is also introduced.The system is divided into MCU module,LCD module and four-wire resistive touch screen module.When installing or using the touch screen,a small mechanical error can be produced easily between LCD and touch screen.The system after calibration procedures can be a good indication of the contents of the touch.
