[MiddleWareDS18B20

Description: 单总线多点测温系统,单总线它采用单根信号线既传输时钟又传输数据,而且数据传输是双向的它具有节省I/O 口线资源结构简单成本低廉便于总线扩展和 维护等诸多优点。本系统中所有的DS18B20都接在单片机的P1.1口上。用一个液晶屏显示,从单片机P3口接上8个开关,与右边的DS18B20 编号对应。当没有开关按下时屏幕显示"which NO you want press which key",要想看那一点处的温度就按下几号键(点击key右边的小红 点,按一下弹下,再按一下弹起)。只能有一个按键按下,当有多个按键下时,屏幕上显示“please press one key only !".-It uses a single bus single clock signal line is also the transmission of data transmission and data transmission is a two-way it has to save I/O port line resource structure to facilitate low-cost and easy expansion and bus Maintenance and many other advantages. The system all the DS18B20 have access at the mouth on MCU P1.1. With a LCD screen display, from the mouth connected to P3 Singlechip 8 switch, with the right DS18B20 Number corresponds to. When there is no screen display when pressing the switch "which NO you want press which key", that the Department wants to look at the temperature of the press a few keys No. (click the right key of the Little Red Point, click under the shells, and then click up). There can be only one button press, when there is more than the next button when the screen "please press one key only!".

Description: 通常我们在51单片机系统中,要用到多个按键时,差不多都是采用的矩阵键盘,这是种比较浪费IO的做法 这里的红外键盘,32个按键却只占用一个I/O口,(这个I/O可以是中断引脚,也可以是一般IO,不过实际验证中发现:接中断管脚时,解码比较可靠,基本不会出错) 当然,更换我电路中采用的编码芯片后,可以扩展至64个按键 -hong wai xian
