基于MSP430F149单片机ADC采样样例程序-MSP-FET430P140 Demo- ADC12, Sample A0, Set P3.4 if A0 > 0.5*AVcc

//

//　Descr iption: 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.
