51单片机C语言的编程技巧 在进行单片机应用系统设计时．汇编语言是一种常用的软件工具。它能直接操作硬件．指令的执行速度快。但其指令繁育统的固有格式受硬件结构的限制很大．且难于编写与调试．同时其可移植性也较差。随着单片机硬件性能的提高．其工作速度越来越快．因此在编写单片机应用系统程序时．更着重于程序本身的编写效率。本文介招的C51交叉编译器就是解决连一问题的利器-51 microcontroller C programming language skills during SCM application system design. Assembly Language is a common software tools. It can directly operate the hardware. Order Execution speed. But their breeding EC Directive format by the inherent structural limitations of hardware great. It is not easy to prepare and debugging. While its portability also poor. With SCM performance of hardware. Their work ever faster. Therefore, in preparing microcontroller applications procedures. More focused on the preparation process itself efficiency. This paper introduces the C51 cross compiler is not even solve the problem of a sharp object

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.
