The touch screen is widely used in embedded devices, but the coordinates of the touchscreen and the coordinates of the screen are asymmetrical and need to be calibrated. Calibration is widely used by open source tslib.Tslib is an open source program that provides touch-screen driven sampling with functions such as filtering, dithering, and calibration, often as a touchscreen-driven adaptation layer, providi
