【摘要】 为解决EtherCAT总线应用于嵌入式系统中主站控制器开发困难等问题，文中设计了一种基于MCU+FPGA+EtherCAT芯片的主站控制器实现方案。采用STM32 MCU作为系统管理芯片，通过FPGA实现了SPI通信控制逻辑对EtherCAT主站芯片(EC-01M)进行实时控制。系统在FPGA上实现了MCU接口模块、寄存器读写模块以及EC-01M主站芯片专用SPI控制逻辑模块。较好地解决了EtherCAT主站控制器在嵌入式系统中的应用难等问题。实际运行结果表明：该系统具有EtherCAT标准协议的兼容性、实时性以及稳定性。更多还原

【Abstract】 In order to solve the difficulties in the development of master station controller in embedded system using EtherCAT bus, this paper designed an implementation scheme of master station controller based on MCU+FPGA+EtherCAT chip.STM32 MCU was used as the system management chip, and the SPI communication control logic was realized through FPGA to control the EtherCAT master station chip(EC-01 M)in real time.The system implemented MCU interface module, register reading and writing module and SPI control logic module dedicated to EC-01 M master station chip on FPGA.The application difficulty of EtherCAT master station controller in embedded system was well solved.The actual operation results show that the system has compatibility, real-time and stability of EtherCAT standard protocol.更多还原
