恳求侠友改改！（电风扇温度，转速，定时控制程序）<br /> keil可以通过，但仿真显示的结果不对，<br /> 按键功能：K1功能；K2移位；K3递增；K4递减；<br /> <br /> 设计的想法是开机显示当前的温度，可以设置时间，<br />上限温度，定时开始时间和定时结束时间。当处在设置<br />的时间段里边时，如果当前温度超过了上限值，则风扇<br />转，其转速受当前温度和上限温度的差值控制，差值越<br />小转速越慢，反之则越快，<br /><br /> 恳求高手们可以给我改改不胜感激！我的联系方式：<br /> QQ：270662589 Email:pmmimosa@126.com<br /><br />#include<reg51.h><br />#include<intrins.h><br
