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.

8279键盘单片机c语言编码，很实用哦。-8279 keyboard Singlechip c language coding, it is practical Oh.

at89s51小系统（带有LCD），用来测试系统及LCD显示的程序，有一定的代表性，可在上面作更改，作为开发的参考资料-AT89S51 small system (with LCD), to test the system and the LCD display procedures, a certain level of representativeness can be changed in the above, as the development of reference materials

停车场显示是日常生活中使用很平常的系统，停车场显示系统的核心是LED显示。本次设计使用KH-310实验箱，使用点阵模块和数码管模块，根据显示的扫描原理，利用8X8点阵模拟实际停车位并由数码管显示车位信息。- Parking is a show system that everyday life is usual to use the information.parking display system is the core of the LED display. The design of the experimental use of KH-310 boxes, the use of dot-matrix modules and digital control module, according to the scan shows that the principle of the use of dot-matrix 8X8 analog actual parking spaces by the digital display of information.

采用12位MAX 197对外部信号采样。采用全周波傅立叶积分算法，对采样信号进行处理，对电力系统的电压有效值、功率等特征量进行实时在线监测；采用全数字测量法测量相位差；并采用自适应技术调整采样间隔，消除非同步采样对计算造成的误差，利用PIC18F458捕获功能实时监测电力系统频率波动，修订采样间隔。分析了各量的测量误差，均达到标准。并提供友好的人机交互界面。-used 12 MAX 197 pairs external signal sampling. Using Fourier-Cycle Integration Algorithm for the sampling signal processing, power systems to the RMS voltage, power characteristics of the volume in real-time on-line monitoring; All digital measuring method phase difference; Adaptive technology and the sampling interval, the elimination of non-synchronous sampling of the calculation error using PIC18F458 capture real-time monitoring of power system frequency fluctuations amended sampling interval. The analysis of the measurement error are up to standard. And to provide a friendly man-machine interface.
