首先，分别对8255、8253进行初始化，设置8255为A口、C口输出，设置8253的计数器0为工作模式3；其次，设置IRQ7的中断矢量，使得有IRQ7中断时调用SERVER；再次，调用INIT对计数值初始化；最后，主程序循环等待中断，开始秒表的计时。 2、 INIT子程序-First, the 8255,8253 initialization, set for the 8255 A-C mouth output, set 8253 as the Counter mode 0 3; Second, set up the interruption vector there, make it there interruption call SERVER; Again, call curl_setopt early to count before; Finally, the cycle of waiting for the main program interruption began stopwatch time. 2, curl_setopt Subroutine

挂接WH_CALLWNDPROC(WM_IME_COMPOSITION),WH_GETMESSAGE(WM_CHAR和WM_KEYUP),前者记录中文,后者记特殊按键和字母符号.-articulated WH_CALLWNDPROC (WM_IME_COMPOSITION) , WH_GETMESSAGE (WM_CHAR and WM_KEYUP), the former Chinese records, the latter in mind the special keys and alphabet symbols.

装置的功能是对温度进行实时监测与控制。由温度传感器DS18B20对温度进行采样和转换成数字信号送入单片机，并与设定的报警温度上、下限值进行比较，信息通过LCD显示出来。如实时温度超过设定的上、下限值，一方面由LCD显示信息，并发出警报声；另一方面自动控制继电器（Relay）开接通或断开，从而控制加热源的开与断，达到对温度进行实时控制的目的。-Device" s function is real-time temperature monitoring and control. Temperature by the temperature sensor DS18B20 sample and converted into a digital signal into the microcontroller, and with the set alarm temperature of the upper and lower limit comparison information through the LCD display. Such as real-time temperature exceeds a set upper and lower limits on the one hand by the LCD to display information, and the alarm sound the other hand, automatic control relay (Relay) to open turn on or off to control the opening and the heat source off, to achieve real-time temperature control.
