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.

说明：  形参只是形式参数，并不参与实际运算，但是形参在同一个函数里要相同，实参是实际参数，参与实际的运算， 有几个形参就对应有几个实参，形参在自定义函数里，实参在主函数里 (Formals only formal parameter is not involved in the actual operation, but parameter in a function to be the same, the argument is the actual parameters involved in the actual operation, several shape parameters corresponding to several arguments, parameter in Custom function, the argument in the main function)

本程序需在DOS下运行。每运行一次可执行程序random.exe，即可显示任意两个 16进制数的加法或减法表达式及其运算结果。在减法运算中，如果被减数小于减数，显示 “Divide Overflow”的提示信息。-the process required under the DOS operating. Every time running executable random.exe. two shows can be arbitrary number of 16 Decimal Addition or subtraction expression and Operational results. The subtraction operation, if less than subtrahend minuend, shows that the "Divide Overflow" message.
