基于C8051F020单片机的某无人机飞控系统硬件平台的设计与开发

Development of the Hardware Platform for a UAV Flight Control System Based on C8051F020

介绍某小型无人驾驶飞机控制系统的硬件平台设计和开发。它以C80 5 1F0 2 0单片机为核心 ,并利用SPI总线和外部数据存储器接口进行DA、串行通信接口和外部RAM的扩展 ,从而具有丰富的高精度模拟信号接口、方便灵活的数字接口和串行通信接口等硬件资源。C80 5 1F0 2 0具有的JTAG接口使开发过程方便高效。同时 ,在设计中绝大多数元器件采用最小型号的贴片封装 ,使该硬件平台具有体积小、重量轻和集成度高的特点。

The design and development scheme of the hardware platform for a UAV flight control system is proposed.The microcontroller C8051F020 is selected as its kernel.With the extension of the DA interfaces and the serial communication interfaces by using SPI bus and EDMI,the hardware platform has abundant hardware resources such as precise analog interfaces,convenient and flexible digital interfaces and serial communication interfaces, and so on.The JTAG interface maximizes the developing efficiency.Because of the minimum package of the most elements,the hardware platform has the characteristics of the small volume,the little weight and the high integration.
