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 control application, known as a 2-channel incremental encoder, converts linear displacement into a pulse signal. By monitoring the number of pulses and the relative phase of the two 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 the quadrature encoder interface. Accordingly STM3210x can handles the encoder signal without any CPU overhead which it is p……
