摘要
本文详细介绍了一种超低功耗数据采集系统的设计与实现。采用MSP430F169作为微控制器,配有液晶显示模块和数据通讯模块,利用嵌入式操作系统μC/OS-II管理任务之间的切换与通信。该系统实现了对模拟信号、数字信号的实时采集和显示,在必要时发送至上位机等功能,系统运行稳定、功耗超低并且携带方便。
This paper describes particularly the design and research of an ultra-low-power data acquisition system. It uses MSP430F169 as micro controller along with LCD display module and the data communication module, and uses the embedded operating system μC/OS-II to manage the communication and switching between tasks. This system realizes the function of real-time acquisition and display in analog signal and digital signal, and if necessary, the data will be sent to the host computer. The system runs stable, low power consumption and easy to carry.
