基于ARM的转台系统仿真通信板设计

Design of Simulation Communication Board of Table System Based on ARM and CAN Bus

随着ARM微控制器广泛应用于各式各样的嵌入式系统中,提出了以ARM为核心器件来设计实现转台仿真通信板;结合转台仿真系统要求对本板卡进行了功能模块划分,对各个模块的功能和组成以及器件的选型做了介绍,探讨了如何利用接口丰富、使用便捷的ARM微控制器来实现A/D与D/A转换,CAN总线通信,以及大量数据的实时存储;阐述了各部分接口电路设计要点,以及主控软件的工作流程和设计方法,并指出了本设计的应用前景。

With the ARM micro-controllers are widely used in a variety of embedded systems,ARM is proposed as the key device to design and implement communication board of table simulation.The communication board was divided into functional modules with the requirements of table simulation system,the function and composition of each module and the selection of devices are introduced,and then probe the path to implement the A / D and the D / A converter,CAN bus communication,as well as real-time storage of large amounts of data with rich interface and convenient ARM micro-controller.At the same time,the interface circuit design features of each module are described in detail,as well as the workflow and design methods of master software,and also pointed out the potential prospect of this design.
