摘要
设计了一种简单且高精度的接口电路,实现了硬件鉴相、倍频(提高精度)和计数,可与微机或DSP并行通讯,并消除了硬件延时可能引起的错误。
In this paper,an encoder interface was designed, in which phase detection, enhancement of resolution and counting of encoder pulses were all implemented with simple hardware, and potential data error due to propagation time delay of the counter was removed. With the interface, a microcomputer or DSP can easily acquire the position data from the encoder through a parallel port.
