基于Intel 8253定时器的两端Asm,包括配套电路,流程图  1。设计基于ISA总线的Intel 8253 的接口电路,用Intel 8253 的1个通道作定时器,演奏C调的各个音符,利用查表程序的方法依次演奏,每个音符演奏1s,停0.5s 演奏三遍后退出程序 2。利用Intel 8253的一个通道产生一个100Hz的方波,用示波器测试信号的正确性  以产生的方波作为另一个通道门控信号。利用此通道测量其高电平的宽度,在PC机显示屏上显示其数值并退出程序 -based on the Intel 8253 timer at both ends of programmers, including matching circuit, flowchart

    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.

    在屏幕上开出三个窗口:起止坐标为(5,10)和(15,30),(5,50)和(15,70),(18,15)和(22,65)。要求可用左右方向键选择左窗口或右窗口为当前活动窗口。当一行字符显示满后(左右窗口一行显示20个字符,下窗口显示50个字符),窗口自动向上卷动一行,输入的字符仍显示与最低一行,窗口最高一行向上卷动后消失。用上下方向键可使活动窗口及下窗口内容同时上卷或下卷。输入‘ESC’后结束程序。(huangyujie)-screen out three windows : starting and ending coordinates (5,10) and (15, 30), (5,50) and (15.70) (18.15) and (22.65). Asked about the direction keys can be used to choose the left or right window to window to window current activities. When his characters show after the expiration of (his show window about 20 characters, the next window displays 50 characters), the window automatically scrolling upward here, the importation of characters showed that the minimum here, his highest window scrolling upward disappeared. Up and down direction keys enable activities under the window and window content, but on the next volume or volumes. Importation "ESC" end after the procedure. (Huangyujie)
