在51的P1口连接8个发光2级管，实现8个发光2级管轮流显示-In 51 of the P1 port to connect eight light-emitting tube 2, the achievement of eight light-emitting display two pipe rotation

本源程序是实现军用卷图机通过输入页码来是卷图机卷至指定得页码的功能，其中实现了卷动中相应页码输入，向前卷动，向后卷动，返回上次操作等操作，但由于时间原因在红外接口部分没有做好接口-the source is military aircraft through the volumes imported map pages is to map volumes to the designated machine rolls in the pages of the function, which achieved a scrolling pages corresponding input, scrolling forward and backward scrolling, the last operation to operation, But because of the time because in the infrared part of interface do not interface. .

基于51单片机的带时间显示和紧急控制的交通灯的设计。 此程序在硬件上调试通，用定时器1延时，外部中断0接紧急控制，R0为100MS延时常数，R2为状态延时常数，8279控制数码管显示时间,用P1口控制双色灯-With 51 single-chip based on the time display and the emergency control of traffic lights design. On this process in hardware debugging pass, with one delay timer, external interrupt 0 then the emergency control, R0 for 100MS constant delay, R2 for a state of constant delay, digital 8279 control display time control using two-color lights I P1

1，消除按键的抖动问题 因为按键在闭合或断开过程中出现一段抖动期，主要由于按键的不稳定性引起的，这时会呈现一串页脉冲，时间的长短和开关的机械特性有关。一般在5ms~10ms之间。为保证CPU对键的一次闭合作一次处理，必须去抖动。在键的稳定闭合或断开时读键的状态。 2，据EICE51原理图编写并调试一个键输入子程序，其功能为判断键盘上有无键输入，若有键入，作去抖动处理后，计算输入键的键号送累加器A。-eliminate jitter button issues as keys or disconnect the closure process for some jitter period, mainly due to the instability of the keys to the cause, then it will result in a bunch of pages pulse, the duration and switches on the mechanical properties. General ~ 10ms between 5ms. To ensure that the CPU in a pair of keys a close cooperation, must go jitter. The key to the stability closed or disconnected when reading the key state. 2, EICE51 schematics prepared and debug a key input subroutine, and its function of determining whether keys on the keyboard input, if typing for to handle jitter, the admission of Bond, Bond sent accumulator A.
