摘要
为实现数据终端的低功耗,设计了以MSP430单片机为核心的低功耗数据终端的总体结构,以低电压、低功耗的外围电路等硬件设计为基础,通过软件实现活动模式与休眠模式的切换、控制外围电路等方法延长CPU休眠时间,减小CPU的工作时间,进一步降低功耗。软件配合硬件使低功耗性能发挥到最大,从而达到减小功耗的目的。经过现场测试,满足低功耗终端使用的要求。
In order to realize low power consumption of data terminal,the overall structure of low power consumption data terminal based on MSP430 is designed,which is based on low voltage and low power consumption peripheral circuit,the software can change the activity mode and sleep mode,control the peripheral circuit and so on to prolong the CPU sleep time,reduce the CPU working time,and further reduce the power consumption.The software and the hardware make the low power performance play to the maximum,so as to achieve the goal of reducing power consumption.After field test,it can meet the requirement of low power consumption terminal.
