摘要
介绍了一种原理简单且实用的光栅信号四细分辨向技术.它利用MSP430单片机的捕获功能实现对光栅正交方波信号进行软件四细分,测量的距离可以通过液晶显示器直接显示出来,并将信号通过MODBUS总线传送到上位机.
A practical technology for grating four fine resolutions of signals is discussed by implementation of the MSP430 MCU for grating the quadrature square waves. The distance is measured by an LCD monitor,and the signal transmitted to the PC by MODBUS.
