DS18S20是一种典型的1-Wire总线接口温度传感器，由Dallas Semiconductor公司生产。DS18S20数字温度传感器提供了9位高精度的摄氏温度测量，同时具有非易失性、用户可编程上下触发门限的报警功能。由于其独特的1-Wire总线接口，使得其可以占用极少的I/O引脚资源，使用起来十分方便-DS18S20 is a typical 1-Wire bus interface, temperature sensor, manufactured by Dallas Semiconductor. DS18S20 digital temperature sensor provides high-precision 9 Celsius temperature measurement, both non-volatile, user-programmable upper and lower trigger threshold alarm. Because of its unique 1-Wire bus interface, making it can take up very little I/O pin resources, is very convenient to use

利用程序中的函数，来读取时钟芯片的秒、分、时、日、月、年、世纪，亦能对其设置时间日期。-procedures for the use of function, to read clock chip seconds, hours, days, months, years, centuries, but also the date of its set-up time.

这是LCD1602与msp430之间的通信,其实可以直接从51移植过来,但是一定要在硬件加上拉电阻,要不然是不通不过的,我说的是你用的是5V的LCD-This is the LCD1602 and communication between the MSP430 can in fact be a direct transplant from the 51, but must be coupled with pull-up resistor in the hardware, otherwise it is unreasonable, however, I say is that you use the LCD is 5V
