Research on Absolute Encoder Communication Based on TMS320F28335
In high-precision servo control applications,it is usually necessary to obtain data measurement information from absolute value photoelectric encoders.Firstly,the characteristics of the absolute encoder and the RS-485 communication principle were analyzed.Then,based on the SCI module of DSP,the encoder communication interface circuit and communication program were designed.The results show that the designed communication interface and program can achieve communication between DSP and encoder.
