使用AT89C2051的红处遥控窗帘 作者：徐福成 　　本文介绍一款使用微电脑管理的、红外遥控器控制的多功能窗帘控制器。该窗帘控制器采用 89C2051 单片机的最小系统设计，控制一个 220V 的可逆、变速电动机控制窗帘的拉开和关闭。 　　窗帘控制器可以使用红外遥控器进行远程手动开、手动关和手动停控制；可以执行事先输入的开启时间和关闭时间进行时间控制；还可以根据室外环境亮度实现环境亮度光控。三种工作方式可以方便地进行选择，当选择时间控制的方案时，数码管还能显示当时小时和分钟时间，不过时间数据只能顺序显示，显示一遍后，略等片刻再显示下一遍时间。另外、电机拉动窗帘的工作的时间长度，电机工作的时候是否有鸣响提示，以及光控状态下环境亮度的控制参数的调整等等都可以通过遥控器进行设置。-use of the red remote control curtain Department Author : Xu cost of introducing the new management of the use of microcomputer, infrared remote control of the multi-function controller curtains. The curtain controller 89C2051 the minimum system design, control of a 220V reversible, variable speed motor control and opened the curtains closed. Curtain controller can use infrared remote control for remote manual open, manual clearance and stopped manually control; Input can be implemented prior to the opening time and the closing time to time control; Also under the outdoor environment can achieve environmental brightness optical brightness control.

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
