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

MCS―51单片机系统扩展 简单的并行接口由数据寄存器和少量的控制电路组成，暂存传送的数据。以锁存器、缓冲器为主要芯片，稍加控制都可以作为简单的并行接口.-MCS-51 single-chip microcomputer system to expand a simple parallel interface from the data register and a small number of control circuit components, temporary storage of data transmission. To latches, buffers as the main chip, a little control can be used as a simple parallel interface.

单片机系统上电后，P0 口和 P1 口都被清 0。然后，你规定一个由 6 个数字构成的序列（每个数字从 0～F 中选取），比如 E、8、9、0、7、F。然后每次当单片机检测到外部中断 0发起中断时间时，读取 P0 口和 P1 口上的状态值，当连续 6 次外部中断事件的对应的数字序列构成你所设定的序列后（举例来说，如果 P0.0 是 1，P0 和 P1 的其他管脚是 0，那么我们称为检测到一次数字 0），从串口打印输出一幅类似下图的 16×16 的ASCII码的圣诞树图片。-Single-chip microcomputer system after power, P0 and P1 mouth I have been ching 0. Then you set a six figure constituted by the sequence (each number from 0 ~ F in selected), for example, E, 8,9,0,7, F. And then each time a single-chip detects external interrupt 0 initiated interruption time, I read the P0 and P1 mouth on the state value, when a row 6 times the corresponding external interrupt events constitute digital sequence set your sequence (for example example, if P0.0 is 1, P0 and P1 of the other pin is 0, then we called a number of detected 0), a printout from the serial port under similar 16 × 16 map of the ASCII code of the Christmas tree图片.
