基于AVRMEG16的多功能航空电子钟设计

摘要

This multi-functional clock uses AVRMEG 16 as the core controller. The clock chip DS3232 provides the reference clock. GPS time signal is received through ARINC 429 bus and the accurate clock label is sticked for the system. And thus, the system meets the requirements of very high precision. For the system, the current time, flight time or test time is displayed in the forms of digital, pointer and combination displaying.%以AVRMEG16作为核心控制器,时钟芯片DS3232提供参考时钟,并通过429总线接收GPS授时信号给系统贴上精确的时钟标签,设计制作了多功能航空电子钟系统.该系统实现了用数显、指针显及混显三种模式高精度显示现时时间、航行时间或测时时间.
