说明：  本代码实现MSP430单片机与温度传感器ds18b20之间的通信，，打开时找dm430-l的eww文件就可以，单片机每隔3秒向上位机传输一次数据，传输数据格式为16进制，（16进制转换为10进制后除以10，就是当前的环境温度），数据输出从单片机的串口0引出。(This code realizes the communication between MSP430 MCU and temperature sensor ds18b20. When you open it, you can find the EW file of dm430-l. The MCU transmits data to the host computer every 3 seconds. The format of data transmission is 16-ary (after conversion from 16-ary to 10-decimal, it is the current environment temperature). The data output is drawn from the serial port 0 of the MCU.)
