利用MSP430F169的AD和DA模块进行编写的程序。通过按键按下的次数来改变数字量的输入，并且在12864上显示出来。里面的程序是齐全的，编写测试通过后直接压缩的。有相应的解释，读起来容易。-MSP430F169 AD and DA modules written procedures. Button is pressed the number to change the digital input and displayed on the 12864. Inside the procedu

msp430f169的ADC和DAC同时输出，输出电压的最大值以及输入电压的最大值都减小了。(Both the ADC and msp430f169 of the DAC are output at the same time, the maximum value of the output voltage and the maximum value of the input voltage are reduced.)
