摘要
给出了一种基于C51的数字式气压高度表的设计方案。设计中采用了压阻式气压传感器,运用了C8051F单片机及UART、SPI等通信技术和低功耗的措施,实现了数字式气压高度表的模块化、小型化和智能化误差补偿,特别适用于无人机之类的小型飞行器上的使用。
A design of a digital atmospheric pressure altimeter based on C51 programming language is presented. In this design, an atmospheric pressure sensor whose resistance changes with pressure is adopted. Many technologies such as C8051F microcontroller, communications with UART and SPI , and measures to lower its power are used. The modularization, miniaturization and intellectualizing to error compensation of the altimeter are accomplished. It is suitable especially for the small-sized aircraft of unmanned machine, etc.
