利用单片机的中断口来测PWM码的宽度，通过本实验仪配备的遥控，单片机解码在数码管上显示（图20）。实际应用例如：红外遥控...

用485实现单片机之间的串行通信。 主机部分发送从机地址，等待从机响应，从机准备好就发数据,发完就接收从机的响应，接受成功就跳出循环，否则重发。-MCU with 485 Serial Communication between. Host of this address from the plane, waiting for the response from the plane, from the plane ready to discuss the data, finished on the reception of the response from the plane. set aside for recycling success, otherwise re-issued.

电子秒表的设计 1、用系统8253定时器提供的55ms定时单位，设计秒表定时程序。 2、有关系统定时方法： PC机系统中的8253定时器0工作于方式3，外部提供一个时钟作为CLK信号, 频率：f=1.1931816MHz。 定时器0输出方波的频率:fout=1.1931816/65536=18.2Hz。 输出方波的周期Tout=1/18.2=54.945ms。8253A每隔55ms引起一次中断-Electronic stopwatch design one, using the system timer 8253 provides 55ms timing units, design stopwatch timing procedures. 2, the system timing method: PC system timer 0 of 8253 working in the way of 3, to provide an external clock as the CLK signal, the frequency: f = 1.1931816MHz. Timer 0 output square wave frequency: fout = 1.1931816/65536 = 18.2Hz. Cycle square wave output Tout = 1/18.2 = 54.945ms. 8253A every 55ms caused a disruption
