msp430内部含有ADC12模块，可以完成12位的模数转换，当对精度或其他指标要求不高时，可以选用430单片机内部的ADC12完成模数转换工作。这里主要实现了一个比较通用的ADC12模块初始化程序，具体的数据存储和处理需要自己在中断处理函数中添加。

-msp430 the internal containing ADC12 module, you can complete a 12-bit analog-to-digital conversion the selection the 430 microcontroller internal ADC12 completed the analog-to-digital conversion accuracy or other indicators do not ask, you can. Here mainly to achieve a more generic the ADC12 module initialization program, specific data storage and processing need to add in the interrupt handler.
