摘要
Abstract
Focusing on the data acquisition challenges of SSI protocol absolute encoders,this study proposes a method to directly acquire data from SSI protocol absolute encoders using DSPs SPI interface or McBSP interface.The system employs the TMS320F28335 as the master control chip and designs an interface circuit between the DSP and the SSI protocol absolute encoder.By properly configuring the registers of the DSPs SPI and McBSP interfaces and processing the interface data,the objective of directly obtaining 13-bit SSI protocol absolute encoder data via the DSP is achieved.This method can be extended to DSP-based acquisition of SSI protocol absolute encoder data of any bit-length,demonstrating strong practical applicability.关键词
