用MSP430F203微控制器为核心构建的控温电热毯。以一个Pt1000热电阻作为传感器，用PID算法以PWM的方式控制加热输出，并通过一个共阳RGB LED显示多种设定和测试温度。通过Timer_A2构建了一个全双工串口与PC通讯。-A heat-blanket application by MSP430F2013 microcontroller. Sensor RTD Pt1000 measure the temperature, and a PWM output control heating power. Just one key is engaged to set the temperature. A common anode RGB three-color LED is used to indicate the setting temperature and the measured temperature. A full duplex serial port module is fulfilled by the Timer_A2.
