用汇编语言实现：通过键盘输入任意两点坐标，在屏幕上开一个窗口，并设定控制窗口的颜色，要求屏幕呈现颜色的变化。(huangyujie)

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.

This example prints out "HELLO WORLD!" by writing directly to the video memory.

应用背景 1.进一步学习汇编语言源程序的编辑，编译，目标文件的链结和可执行文件的执行全过程 2.进一步学习文本的编辑软件，TASM,TLINK和TD的使用方法 3.学习掌握汇编语言的语法规则，练习汇编语言的语法错误查找和排除。 4.通过编制汇编程序，学习分支循环程序的编程方法 关键技术 通过比较法完成8位二进制数转换成十进制数送屏幕显示功能的汇编语言源程序，但有很多语法错误。要求实验者按照原样对源程序进行编辑，汇编后，根据TASM给出的错误信息对源程序进行修改，直到没有语法错误为止。然后进行链接，并执行相应的可执行文件。正确的执行结果是在屏幕上显示：25+9=34。
