    通过DS18B20读取温度(范围-55C~125C,精确到小数点后一位),通过4位数码管显示出来。 当温度为正且百位为零时,不显示,当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。(Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.)

    网络控制单片机proteus仿真 利用网络控制单片机的LED、LCD,我只是整理了一下,方便大家学习,版权归原作者,网页也麻烦站长做好了,有一个上位机,点击自动运行一段程序和打开www.mcufz.com/tcp.htm,之后会自动关闭,有的杀毒软件会报是病毒,放心使用。 开始要安装一个WinPcap软件,不安装它不能仿真,然后运行仿真文件,过一会可以看到LCD显示出了IP地址50。1。1。1 (Proteus simulation network control the use of single-chip microcontroller network control LED, LCD, I am just finishing a bit, to facilitate learning, belongs to original author, the website also do a good job of head trouble, there is a host computer, click Automatic operation for some procedures and open www.mcufz.com/tcp.htm, will automatically shut down after some anti-virus software will be reported to viruses, ease of use. WinPcap started to install a software, do not install it can not simulation, and then run the simulation documents LCD moment we can see the IP addresses shows that 50. 1. 1.1)
