串口显示ps-2鼠标实验，显示鼠标采集到的x位置y位置位移量-Ps-2 mouse, serial experiments show, show the mouse capture to the x position y position displacement

通过串口模拟GPS的程序，用鼠标相对于屏幕中心位置的偏移来模拟移动速度。-GPS through the serial port simulation program, with the mouse position relative to the center of the screen to simulate the speed of the offset.
