Design of ARM-based Embedded Ethernet Interface
Design of ARM-based Embedded Ethernet Interface.pdf (Size: 142.18 KB / Downloads: 80) Abstract Currently device with microcontroller has been widely used in industrial field. However, a large number of devices don’t have the network interface and the data from them can not be transmitted in network. A design of ARM processor-based embedded Ethernet interface is presented. INTRODUCTION With the development of network technology and communication technology, the need that industrial control can be completed via network has become a trend. In traditional industrial control system or data acquisition system, the structure that one host connects multiple serial devices through multiport serial cards is adopted. The task of host is to communicate with each serial device, process data and interact between the operator and computer. This structure is feasible in the case of fewer devices, lower transmission rate. But when a host needs to connect more serial devices at the same time with higher transmission rate and the data processing is more complex. SYSTEM DESIGN The main purpose of the design is to make traditional monitoring system have the capabilities of remote monitoring or data transmission by introducing Ethernet interface it. In the design, structured modular design method is adopted and the system is mainly composed of SPI communication module, processor module and Ethernet interface module, as shown in Fig. 1. SOFTWARE DESIGN μC/OS-П Transplanting For the transplanting of OS μC / OS-П, its main task is to re-write the codes which are associated with the processor and compiler[3]. The codes include the following: redefinition of compiler-related data type, interrupt-switching code, stack growth direction, the initialization function for task stack, task-switching function and so on. The transplanting is completed in the following environments: the compiler tool is IAR FOR ARM and EasyARM8962 development board is used as target board. In order to transplant μC / OS-П into the ARM processor LM3S8962, three ARM architecture-related documents: OS_CPU.H, OS_CPU_A.ASM and OS_CPU_C.C are modified. CONCLUSION In order to transmit the data from an existing device with SPI interface to network, a embedded Ethernet interface based on ARM processor is designed. On the basis of hardware platform, real time OS μC / OS-П is transplanted into the microcontroller LM3S8962 and the SPI serial data and Ethernet data packets can be converted to each other by software programming. For traditional serial devices, the design provides an effective implementation to connect Ethernet and the remote devices with SPI serial interface can be changed into the shared resources in network. This design can be used widely in remote data acquisition and control system in industry.
