用内部AD转换模块和温度传感器来测量温度，当温度达到设定值时，指示灯会亮。-Descr iption: se ADC10 and the integrated temperature sensor to detect temperature gradients. The temperature sensor output voltage is sampled ~ every 120ms and compared with the defined delta values using an ISR.(ADC10OSC/4)/64 determines sample time which needs to be greater than 30us for temperature sensor.ADC10 is operated in repeat-single channel mode with the sample and convert trigger sourced from Timer_A CCR1. The ADC10IFG at the end of each converstion will trigger an ISR.ACLK = n/a, MCLK = SMCLK = default DCO ~ 1.2MHz, ADC10CLK = ADC10OSC
