MCS51 basic debugging procedures, including 8255, keyboards, LED, etc.

8051asm 汇编器source code.-8051asm assembler source code.

DS1302的驱动程序，C51编的，最后由proteus仿真的，可以显示设定时间，程序中的延时函数是由汇编语言实现，也就是说这程序是C和汇编混编的。-DS1302 driver, C51 series, and finally by the Proteus simulation can show the set time delay proceedings by the assembly language function is to achieve, that is to say that the procedure is of mixed C and assembler.

AT24C16的读写程序，I2C接口，已经通过测试，注释很详细-AT24C16 literacy program, I2C interface, has passed the test, the Notes are detailed

Quoted from the author Igor Skochinsky In July I had the honor to speak at the Recon conference in Montreal, Canada. It was my first conference but I really liked the experience. I hope I’ll be able to attend it in future. The presentations were recorded and hopefully will appear on the Recon site soon but for now you can check out the slides . I have also uploaded some of the tools I mentioned, most notably various filesystem extractors compiled for Win32 .

单片机数字电压表汇编程序.希望大家分享哦-Single-chip digital voltage meter assembler. Hope that we share Oh

利用PC机的硬件定时8253, 编制秒表延时(0~9秒)程序.要求: 按任意键,开始计时, 在屏幕上以1秒间隔从0到9显示 按ESC键,计时停止.-use of PC hardware-timed 8253, the establishment of a stopwatch Delay (0 ~ 9 seconds) program. Requirements : by the arbitrary button, the timer on screen to a second interval from 0 to 9 shows by the ESC key, a time to stop.

关于8086汇编的一些实验程序，对于汇编程序的编写很有借鉴。-on the 8086 compilation of some experimental procedures, procedures for the preparation of the Compendium very useful reference.

一个记事本源程序-a notebook source

masm,debug,link还有上课时的源程序，希望对大家有用-can, debug, link still class of the source, a member of the useful

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.
