DSP平台下ARINC429总线的驱动设计

摘要

Aiming at the critical problem of data communication between DSP and other ARINC429 devices, we designed a set of ARINIC 429 bus driver. Analyzed the chip HI3584 which implements the protocol of ARINIC 429 bus, we designed a universal driver interface combining with this scheme, and gives realization of program. The result shows that the driver is stable and reliable. In the later project, the driver can be used directly with little modification.%针对某航空弹载设备在DSP平台下与其他ARINC429设备之间数据通信这一关键问题，通过分析ARINC429总线协议芯片HI3584的具体功能，利用软件工程化方法，设计出通用性良好的ARINC429总线驱动程序，并给出了驱动程序的实现过程。测试结果证明，该驱动程序满足了设计的需求，具有稳定性好、可靠性高、通用性强等特点，在以后的类似项目中仅做少许修改便能直接应用。
