基于STM32和FPGA的CAN总线运动控制器的设计

Design of motion controller with CAN bus based on STM32 and FPGA

运用低功耗C0rtex-M3微控制器STM32F103VBT6和FPGA芯片设计一种基于CAN总线的运动控制器。介绍系统的体系结构、主要硬件设计和软件结构。利用FPGA高速处理能力实现控制算法,与外界通信采用STM32和CAN总线技术,系统稳定可靠,另外,将设计好的FPGA程序或是C程序进行封装,系统的可移植性强。

A motion controller based on CAN bus is designed with STM32 and FPGA. A low consumption micro-controller COrtex-M3 and a FPGA chip STM32F103VBT6 are used. The structure of the system and the main software and hardware design structure is introduced.Some control algorithm are realized by using the high processing capacity of FPGA. STM32 and the CAN bus are used to communicate with outside part.The system is stable and reliable,otherwise, the portability of the system is strong by packaging the FPGA program or C program.
