摘要
文章介绍了编码器的工作原理,根据输出的三相脉冲的特点,设计了加/减可控的脉冲计数器,实现了对码盘角度信息的读取,同时根据DSP的SPORT串行口协议,设计能够与串口进行通信的并行-串行转换电路。
The principle of the encoder is introduced in the article.According to the character of the three-phase pulse,the addition/subtraction counter is designed.And the angle information is read on the encoder.On the basis of the DSP SPORT serial port agreement,a parallel-to-serial converter is completed which is capable of communicating with serial port.
