这是在用MSP430写的LCD12864和温度传感器18B20的驱动程序。-This is written with MSP430 and temperature sensors LCD12864 driver 18B20.

显示字符与时钟,按键调试定时器, 3个按键可以设定时间,程序有8段时间段,时间到达每个时间段,9个输出相应变化.-Show the character and clock, timer debug button, three button can set the time, procedure time has paragraph 8, the time taken to reach each time period, the corresponding changes in the output 9.

定时器的应用，两种点灯的方案，用它以熟悉定时器应用-Application of timer, two light up the program, use it to become familiar with the Timer Application

本系统主要用于旅游景点记录游客人数，并限制旅客的流量。采用红外传感器通过检测人体红外并对通过人数进行计数，通过红外对管将检测到的数据发送至单片机，单片机处理后送至数码管显示，数码管显示的数据即为通过的人数，并通过设定值限制旅客数量。当游客超量是系统将给出相应的提示，禁止游客再进入。以更好的保护旅游景点的生态环境。-This system is mainly used for tourist attractions recording the number of visitors and limit the flow of tourists. Use of infrared sensors by detecting the human body by infrared and number of people count on the tube will be detected by infrared the data sent to the MCU, MCU after treatment sent to the digital LED display, digital LED display of the data shall be the number of through and through setting limits the number of passengers. When the visitors over-the system will give the appropriate prompts to prohibit visitors from re-entering. To better protect the tourist attractions of the ecological environment.

DS12887时钟苡片，一定可行，因为我试过的，谢谢帮我开通，我真的想在这里找点东西，谢谢站长了。-DS12887 Clock jobi films, always practicable, because I tried, thank you, help me open, I really would like to find something, I would like to thank the station.

一个很好的例程，希望对您有帮助，欢迎探讨
