一种超低功耗便携式高斯计的设计

摘要

从硬件和软件两个方面介绍了一种超低功耗便携式高斯计的设计方案.该方案在硬件上采用HT7130稳压芯片、STM8L152单片机、TM7709数模转换器以及HT1621液晶驱动器作为核心芯片,软件上以单片机进行电源管理,结合外围芯片的低功耗控制,最终达到了1000h的电池寿命.%This paper introduced a design of ultra low-power portable gauss meter in terms of hardware and software. The design used the HT7130 regulator chip, STM8L152 microcontroller,TM7709 digital to analog converter and the HT1621 LCD driver as the core chip. And the design realized power management on the microcontroller, combined with low-power control of peripheral chips. It achieved 1 000 hours of battery life finnally.
