4位密码锁完成

共享完整的LIN通讯程序代码，适用于主节点和从节点，适用芯片MC9S12XEP100,飞思卡尔的16位单片机在此程序的基础之上稍微修改下寄存器就可以适用了(LIN communication procedures to share the complete code for the master node and slave nodes, for chip MC9S12XEP100, Freescale 16-bit microcontrollers based on this procedure can be slightly modified for the next register)

LCD液晶显示程序，在AT89S52上运行成功，其也可以用于其 他的处理器(LCD liquid crystal display program, run on AT89S52 is successful, it can also be used for the processor)

stm32舵机控制程序，完整工程源码。pwm波输出(stm32 steering gear control procedures, complete source project)

红外遥控七彩led灯带，包好贪吃蛇，流水灯等多种模式(Infrared remote control lamp belt, pack a variety of modes)

按键控制PWM占空比，利用按键控制PWM的占空比调节直流电机转速，LED显示(Key control PWM duty ratio)

根据stm32f103自带DA功能和DMA实现输出正弦波,可根据改变定时器周期改变正弦波频率。(According to the DA function and DMA of stm32f103, the output sinusoidal wave can be realized, and the frequency of sinusoidal wave can be changed according to the period of timer.)

基于atmega16l usart的实现(atmega16 usart)

测试电脑鼠各个红外探测器的算法，可自行调试(Test each computer mouse infrared detector algorithm, self-debugging)

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.)
