基于ARM Cortex-M4双网口扩展的设计与实现

Design of Dual Ethernet Ports Expansion Based on ARM Cortex-M4

该文针对工业控制领域双网口通信的需求,使用意法半导体(ST)新推出的高性能ARM Cortex-M4内核的微控制器芯片STM32F437,结合Microchip(微芯)公司的以太网控制器芯片ENC624J600,进行了双网口扩展设计。对STM32F437通过并行FSMC总线与ENC624J600之间的软硬件设计进行了阐述,并运用到了实际产品中。

Demand for dual ethernet ports in industrial control area,using STMicroelectronics（ST） new high-performance ARM Cortex-M4 core microcontroller chip STM32F437,combined with Microchip ethernet controller chip ENC624J600,conducted a two-port network expansion design. This system described the hardwaresoftware design between STM32F437 parallel FSMC bus and ENC624J600,and applied to the actual products.
