实现正余弦信号硬件细分功能，可以进行可逆计术，测量激光干涉仪位移信号，利用LCD显示最终位移。-To achieve the function of the chord signal hardware segmentation, can be reversible measurement, measurement of laser interferometer displacement signal, the use of LCD display the final displacement.

读取鼠标传感器采集到的位移速率，使用的硬件平台是stm32c8t6(Read the displacement rate collected by the mouse sensor)
