AT89C2051单片机与PC机的RS232通讯接口子程序，实现管理科学。

HZK24，单片机编程必备，基于UCDOS的24点阵-HZK24, single-chip programming necessary, based on the 24 lattice UCDOS

刚购买的51单片机sch原理图和c语言程序，里面有详细的电路原理图和c语言程序，自己做单片机学习班的可以下载来参考-Just purchased 51 Singlechip sch schematic and c language program, which has a detailed circuit schematic diagram and c language program, to do their own single-chip learning classes can be downloaded to a reference

51单片机上实现对PS2手柄的解析，已经实验通过。-51 microcontroller implemented on PS2 handle parsing experiment has already been passed.

简易信号发生器+Protues仿真,函数波形发生器产生波形表，通过DA转换产生正弦波。-Simple Signal Generator+ Protues simulation, waveform function generator waveform table, have a sine wave through the DA converter.

利用单片机控制的8255键盘控制实验汇编成序-MCU 8255 using the keyboard to control the experimental sequence was compiled

使用89S52为核心做的USB键盘,注意修改了一下windows设备描述符以及端点处理等就行了。用了一个4*4的小键盘,有0-9十个数字键, Num Lock键,Caps Lock键,Shift键,Ctrl键,Alt键,回车键等。 最多可以有三个键同时按下，如果相交的话，最多只能两个键按下-89S52 use as the core of the USB keyboard to do, pay attention to modify the look and the windows device descriptor, such as treatment endpoint on the list. Used a 4* 4 small keyboard, has the number keys 0-9 10, Num Lock keys, Caps Lock key, Shift key, Ctrl key, Alt key, enter key and so on. Can have up to three keys pressed at the same time, if the intersection, then a maximum of only two keys pressed

具有固定的“红灯―绿灯”转换间隔，并自动切换。它们一般由“通行与禁止时间控制显示、红黄绿三色信号灯和方向指示灯”三部分组成。在交通灯的通行与禁止时间控制显示中，通常要么东西、南北两方向各50秒；要么根据交通规律，东西方向60秒，南北方向40秒，时间控制都是固定的。交通灯的时间控制显示，以固定时间值预先“固化”在单片机中，每次只是以一定周期交替变化。-having fixed the "red light-green light" switch partitions, and automatic switching. They are generally from "prohibiting access and time control, red-yellow-green lights and direction indicator" is composed of three parts. Traffic lights in the passage of time and prohibit control indicates that things are usually either the north-south direction of the two 50 seconds; either on the basis of traffic laws, an east-west direction 60 seconds, 40 seconds north-south direction, the time control are fixed. Traffic lights to the time control, a pre-fixed time value "cured" in SCM, each is a certain cycle alternation.
