【摘要】 飞控计算机作为多旋翼无人机飞行控制系统的核心单元,能够实现诸多复杂的数据采集和飞行控制及导航功能,其运行过程中要处理、存储大量的数据。为满足较大数据量的存储需求,本文设计了一种以Cortex-M7处理器STM32F767为内核的飞控计算机存储电路,通过外围扩展AT45DB641E作为数据存储模块,实现对外部数据的读写、擦除等基础功能。系统进行了大量的实验验证,数据能够在极短时间内完成写入和读出,并且能保证数据的完整性和准确性,证明该电路设计可供飞控计算机做数据存储使用。更多还原

【Abstract】 As the core unit of the unmanned multi-rotor aircraft flight control system,the flight control computer needs to realize a lot of complex data acquisition,flight control and navigation functions,which requires a large amount of data to be handled in the whole process. To meet the requirement of large amount of data storage,a flight control computer storage circuit with the kernel of cotex-m7 processor STM32 F767 is designed. It uses AT45 DB641 E to expend the data storage module to complete reading,writing and erasing external data,with. After verification,the data can be read or written in a short time,and it can guarantee the integrity of the data,these demonstrate the circuit can be used as the data storage of flight control computer.更多还原
