IAR环境下的MSP430F149，以温度传感器的电压值为采样信号的AD采样程序，采样间隔为80ms。-　Descr iption: Use ADC12 and the integrated temperature sensor to detect

　temperature gradients. The temperature sensor output voltage is sampled

　~ every 80ms and compared with the defined delta values using an ISR.

　(ADC12OSC/256)/ determines sample time which needs to be greater than

　30us for temperature sensor.

　ADC12 is operated in repeat-single channel mode with the sample and

　convert trigger sourced from Timer_A CCR1. The ADC12MEM0_IFG at the end

　of each converstion will trigger an ISR.

　ACLK = n/a, MCLK = SMCLK = default DCO ~ 800k, ADC12CLK = ADC12OSC
