摘要
电源电路设计成软开关,实现了仪表的智能化控制。利用MSP430F149自带的12bitA/D转换系统实现了A/D转换。显示部分采用一个点阵液晶实现显示功能。MSP430F149低功耗的特性,使整个仪表功耗极低,符合手持式仪表的特点。
The instrument can be controlled intelligently because of the design of soft-switch for the power circuit.In the system of the instrument realize A/D conversion by utilizing its 12-bit A/D converting part in MSP430F 149.By using the dot crystal displayer to achieve the function of display. The feature of very low dissipation for MSP430F 149 itself, that make the instrument to be very low dissipation, which is just fit the characters of the portable instrument.
