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.

电动车从起跑线出发(车体不得超过起跑线),沿引导线到达B点。在“直道区”铺设的白纸下沿引导线埋有1~3块宽度为15cm、长度不等的薄铁片。电动车检测到薄铁片时需立即发出声光指示信息,并实时存储、显示在“直道区”检测到的薄铁片数目。
(2)电动车到达B点以后进入“弯道区”,沿圆弧引导线到达C点(也可脱离圆弧引导线到达C点)。C点下埋有边长为15cm的正方形薄铁片,要求电动车到达C点检测到薄铁片后在C点处停车5秒,停车期间发出断续的声光信息。
(3)电动车在光源的引导下,通过障碍区进入停车区并到达车库。电动车必须在两个障碍物之间通过且不得与其接触。
(4)电动车完成上述任务后应立即停车,但全程行驶时间不能大于90秒,行驶时间达到90秒时必须立即自动停车。
