用89C51，外接晶振，复位电路，二个数码管，二个按键，做一个电子秒表，具体要求为用按键起停电子表，可用按键设计倒计时时间(如10S，20S，60S),并启动倒计时功能,能用按键选择以上两功能之一-With 89C51, an external crystal oscillator, reset circuit, two digital tube, two buttons, making an electronic stopwatch, and specific requirements for the use button start-stop electronic watches, key design can be used countdown time (such as 10S, 20S, 60S), and start the countdown function, can be used for more than two buttons select one of the functions

基于DS18B20温度传感器的设计程序 要求为：第一，由DS18B20获得外部温度信息然后通过数码管显示，显示值为三位，两位整数，一位小数。第二，判断温度是否大于 50℃，若温度在50℃以上，显示红色发光二极管发光；若温度在50℃以下，显示绿色发光二极管发光。-DS18B20 temperature sensor based on the design of procedural requirements: first, by DS18B20 access to external temperature information through a digital display, showing a value of 3, two integer, a decimal. Second, to determine whether the temperature is greater than 50 ℃, if the temperature at 50 ℃, which indicates that the red light-emitting light-emitting diodes if the temperature below 50 ℃, showing a green light-emitting diode LED.

与中断矢量设置与读取有关的DOS功能调用，本例演示了如何编写中断服务程序，如何安装（将中断服务程序的地址设置到中断矢表中），以及如何通过软中断指令调用中断服务程序。为了突出重点，本例中中断服务程序代码未驻留内存。-and vector interrupt settings and read the DOS function calls, which in this case demonstrated how to prepare interrupted service procedures, how to install (to be interrupted service procedures set up to address the interruption vector table), and how soft interrupt directive calling service interruption program. To highlight key issues, in this case the interruption of services not the presence of code memory.
