摘要
ARINC429总线具有结构简单、性能稳定、传输可靠、抗干扰能力强等特征。在需要高可靠性、高集成度设计的应用领域,可以采用SPI接口的ARINC429协议芯片HI-3593实现数据协议处理,与ARM处理器完成ARINC429总线数据收发功能。基于此,笔者围绕该系统架构分析了各部分的功能,并对硬件接口进行了详细设计。
The ARINC429 bus has the characteristics of simple structure,stable performance,reliable transmission,and strong anti-interference ability.In application areas that require high reliability and high integration design,the ARINC429 protocol chip HI-3593 with SPI interface can be used to realize data protocol processing,and the ARINC429 bus data transceiver function can be completed with the ARM processor.Based on this,the author analyzes the functions of each part around the system architecture,and designs the hardware interface in detail.
