单片机P1口与4个按键连接,用于信号幅度和频率调节操作键。单片机P0、P2.7、P3.6(-WR)与DA0832、2个741(运放)连接构成波形信号输出电路。
编程使波形信号输出电路输出正弦波信号,并且可通过操作键调节信号的幅度和频率。幅度和频率调节级别从0~10,共11个等级。
-Singlechip P1 I connect with the four buttons for the signal amplitude and frequency adjustment operation keys. Singlechip P0, P2.7, P3.6 (-WR) and DA0832, 2 months 741 (operational amplifier) to connect constitute waveform signal output circuit. Programming so that waveform signal output circuit output sine wave signal, and can be operated keys adjust the signal amplitude and frequency. Amplitude and frequency adjustment level from 0 ~ 10, a total of 11 grades.

经过一段时间的使用,上次的硬盘MP3播放器增加了USB下载文件功能;
汉字LCD显示功能;子文件夹功能等。并对软件做了一些修改。并将
硬件电路图画出来了。由于做得仓促,难免有不妥之处,请大家谅解,
欢迎指出错误。谢谢。-After a period of use, the last of the hard disk MP3 player, an increase of USB download files function characters LCD display Subfolders functions. And the software to do some modifications. Hardware circuit and the pictures came out. As a result of doing a rush, inevitably something wrong with the U.S. understanding, please welcome to point out the error.谢谢.

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.
