Design and implementation of data communication module for a multi-motor drive and control integrated system based on DSP

Abstract

This paper focuses on the design and implementation of data communication module for a multi-motor drive and control integrated system based on DSP. A kind of overall design for data communication is firstly presented due to the integration of DSP and W5300. Secondly, the real-time data communication under RTX is introduced. In this paper, UDP protocol is adopted and data sending is realized by using socket programming. After that, the complete communication function is given and the data communication between DSP and W5300 is implemented. The data communication method between DSP and FPGA is realized through a dual port RAM afterwards. Finally, Ethernet communication test is conducted based on the self-designed multi-motor drive and control integrated system to verify the reliability and real-time performance of this data communication module.
