这是一个用MSP430单片机设计的基于FYD12864LCD的数字电压表的C程序。系统主要实现对电压的测量。其中，ADC采用MSP430149单片机内部自带的12位AD转换器。输入信号的最大值为+2.5V，你也可以选择其他参考源，使输入信号最大可达+3.3V。-This is a single-chip design using MSP430-based digital voltage meter FYD12864LCD the C program. System is mainly to achieve voltage measurements. One of, ADC using the internal built-in MSP430149 Singlechip 12 AD converters. Maximum input signal for+2.5 V, you can also select other reference source, so that the input signal up to+3.3 V.
