IAR环境下 MSP430-149F，以参考电压为采样信号的ADC采样示例程序，当采样到的电压A0>0.5*AVcc，P3.4（LED）置位，否则复位。
MSP-FET430P140 Demo- ADC12, Sample A0, Set P3.4 if A0 > 0.5*AVcc
Description: A single sample is made on A0 with reference to AVcc.
Software sets ADC10SC to start sample and conversion- ADC12SC
automatically cleared at EOC. ADC12 internal oscillator times sample (16x)
and conversion. In Mainloop MSP430 waits in LPM0 to save power until ADC12
conversion complete, ADC12_ISR will force exit from LPM0 in Mainloop on
reti. If A0 > 0.5*AVcc, P3.4 set, else reset.

62256在单片机上的应用,C语言源码,Keil uVision3工程文件,附原理图及说明学习文档
62256简介：
62系列是最常用的单片机系统扩展RAM元器件，其类型有6216、6232、6264、62128、62256或62512等多种，62后面的数字表示此元器件中可以存储的位(单位：千bit)，我们通常的说法是将此值除以8，比如62256将256除以8，我们一般称之为32K的RAM。
如果学习过二进制就可以知道，区分两个字节需要一根地址线就可以：0或者1；而区分四个字节需要2根地址线；区分八个字节需要三根地址线…..以此类推，我们可以计算出要区分32K的RAM区，需要15根地址线，也就是器件上面的A0-A14管脚用于确定唯一的一个字节内容。
我们现在学习的51单片机是8位的，所以必须用两个IO口来联接这个RAM器件，通常我们用P0（低字节）和P2（高字节）两个端口来确定此器件的地址，而P0口是51单片机标准的总线口，是地址线和数据线复用的，所以与62256联接时需要加一片锁存器来锁存地址。即先将地址送到锁存器（通常用74HC373）中，然后P0口空闲下来后开始接收或发送数据至62256。
