基于中断控制的声光报警器的设计.采用中断方式，设计一个声光报警器的硬件电路和控制程序。程序运行时，一旦8位开关信号量状态满足设定条件，就触发中断，使发光二级管按规律闪烁，同时扬声器播放一段音乐。 硬件设备包括一台微机、一个MFID微机实验箱、一块T型板，2输入四与门 74ls08、8位总线驱动器 74ls245、LM386A音频放大器、排阻、扬声器各一个，发光二极管8个，470uF电容2个、104电容4个，插线若干。 -Interrupt-based control of sound and light alarm design. Using interrupt mode, designing a sound and light alarm hardware circuits and control procedures. The program is running, once the 8-bit switch signal to set the amount of state to meet the conditions to trigger interrupts, so that light-emitting diode flashes according to the law, while speakers play a piece of music. Hardware includes a computer, a computer simulation, MFID box, a T plate, 2 input 4 and gate 74ls08, 8-bit bus driver 74ls245, LM386A audio amplifier, exclusion, speakers of a light-emitting diode 8, 470uF capacitor 2 a, 104 capacitors 4, plug-line number.

LPC2103的第一个实验：流水灯，用proteus7仿真，C语言代码，在Keil3中编译，文件内已有完整的工程和仿真图了。-The first experiment LPC2103: water lamp, with proteus7 simulation, C language code, compiled at Keil3 in the paper that has a complete map of the engineering and simulation.

请将下载的2个插件内容拷贝到uVision 的安装目录下的 KeilC51BIN 中 2. 修改 Tool.ini, 此文件位于 uVision 的安装目录 keil 下. 请将下面的内容 添加到 [C51] 部分的后面. AGSI1=ledkey.dll ("ledkey") AGSI2=simboard.dll ("simboard") 3. 重启uVsion. 进入Debug 模式, 打开菜单Peripheral, 发现增加了2项 分别是键盘LED仿真板，51实验仿真板。-Please download the contents of two plug-ins are copied to the installation directory uVision under KeilC51BIN 2. Modify Tool.ini, this file is located in the installation directory uVision under keil. Please Add the following line to [C51] part of the back. AGSI1 = ledkey.dll (ledkey) AGSI2 = simboard.dll (simboard) 3. Reset uVsion. entered the Debug mode, open the menu Peripheral, found an increase of 2 are keyboard LED emulation board, emulation board 51 experiments.
