51单片机模拟PS2键盘，当接收到触发信号时，向PC发送特定键值，从而达到预期的目的，可以用在很多工控场合。本程序已经通过开机自检，可以在设备管理器里面看到。(51 single-chip analog PS2 keyboard, when receiving the trigger signal to the PC to send a specific key, so as to achieve the intended purpose, can be used in many industrial applications. This program has passed POST, you can see inside the device manager.)

说明：  对一路工频交流电（频率波动范围为50 ±1Hz、有失真的正弦波）的电压有效值、电流有效值、有功功率、无功功率、功率因数进行测量的数字式多用表。通过LCD12864显示(Frequency of the AC all the way (the frequency of fluctuations in the range of 50 ± 1Hz, there is distortion of the sine wave) RMS voltage, RMS current, active power, reactive power, power factor measurement of the digital multimeter. LCD12864 show through)

说明：  AD9833在stm32f103的程序，模拟SPI通讯，便于移植(The program of AD9833 in STM32F103 simulates SPI communication and is easy to transplant.)

学4年来做过的竞赛以及老师的科研项目所积累下来的c51源代码，一共有40(4 years of study done as well as the Teacher of the competition accumulated research c51 source code, a total of 40)

74hc595芯片的使用 51控制595芯片的io拉高(74hc595 chips 595 chips using 51 control pulled io)

本总体方案完成国标GB20600-2006数字电视地面广播传输系统基带部分功能。 输入数据码流经过扰码器（随机化）、前向纠错编码（FEC），然后进行比特流到符号流的星座映射，再进行交织后形成基本数据块，基本数据块与系统信息组合（复用）后并经过帧体数据处理形成帧体，帧体与相应的帧头（PN序列）复接为信号帧（组帧），经过基带后处理转换为输出信号（8MHz带宽内）。该信号经变频转换为射频信号（UHF和VHF频段范围内）。用C程序设计了图形交互界面，可以在界面上直接设置调制参数。(The overall program completion GB GB20600-2006 digital terrestrial television broadcasting transmission systems baseband function. The input data stream through the scrambler (randomization), forward error correction (the FEC), then the symbol constellation mapping bitstream to the stream, and then after forming the basic block interleaving, the basic data block and information combined system ( multiplexing) after data processing and after the frame body forms a frame body, frame body with a corresponding header (PN sequence) multiplexed signal frame (framing), after post-processing baseband signal is converted to an output (internal 8MHz bandwidth). The signal is downconverted to a radio frequency signal (in the VHF and UHF frequency range). C program designed graphical interface, you can set modulation parameters directly on the screen.)
