摘要
系统采用微芯公司dsPIC24FJ系列单片机作为控制CPU来完成的。阐述了该系统的设计思想,在完成系统基本功能的情况下,重点描述了在降低功耗方面所做的关键性设计,即单片机芯片的选择、DC-DC芯片的选择和软件部分在降低功耗上的智能处理,最终实现控制总功耗为最低。
The system uses Microchip Technology Company＇s dsPIC24FJ series single-chip microcomputer as control CPU to complete. First it elaborates this designs concept. And in the situation of completing the system basic function, the article describes the aspect of the crucial design in reducing the power, such as, choosing single-chip microprocessor, choosing DC-DC chips, and intelligent processing of reducing power in the software part. And realization of control for the lowest total power consumption finally.
