STM32F10xxx正交编码器接口应用笔记应用笔记STM32F10xxx正交编码器接口STM32F10xxx正交编码器接口应用笔记Abstract---The quadrature encoder which is very popular in the motor servo controlapplication,known as a2-channel incremental encoder,converts linear displacementinto a pulse signal.By monitoring the number of pulses and the relative phase of thetwo signals you can track the position,the direction of rotation and speed.In ddition,a third channel,or index signal,can be used to reset the position counter.STM3210x which is the MCU based on ARM latest core-Cortex-M3,integrates thequadrature encoder interface.Accordingly STM3210x can handles the encodersignal without any CPU overhead which it is p
