本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

这是一个为数不多的用C语言编写的PIC12C508的RGB灯的小型控制器，交流同步信号检测，七彩跳变+七彩渐变，做LED的朋友可以参考，程序可以直接使用的；(This is a small controller RGB lights a few written by C PIC12C508, AC synchronous signal detection, colorful jump+ colorful gradient, do LED friends can reference, the program can be used directly )

基于STM32F4的四轴航拍平台。以STM32F407为控制核心，四轴飞行器为载体，辅以云台的航拍系统。硬件上由飞控电路，电源管理，通信模块，动力系统，机架，云台伺服系统组成。算法上采用简洁稳定的四元数加互补滤波作为姿态解算算法，PID作为控制器，实现飞行，云台增稳等功能(Four axis aerial platform based on STM32F4. Taking STM32F407 as the control core, the four axis flying vehicle as the carrier, and the aerial camera system with ptz. The hardware is composed of flight control circuit, power management module, communication module, power system, frame and PTZ servo system. The algorithm uses a simple and stable four yuan number plus complementary filtering as the attitude calculation algorithm, and PID is used as a controller to achieve flight, PTZ stability, and other functions)

基于示波法的电子血压计程序，包括脉搏测量。控制器采用STM32F103C8T6。包含数据核心算法程序。( Based oscillography electronic sphygmomanometer procedures, including pulse measurements. Controller uses STM32F103C8T6. It contains data core algorithm program.)

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)

AVR,JTAG仿真软件，内涵源程序和电路图，直接烧写进单片机就可以在线仿真的(AVR, the simulation software of JTAG, content of the source code and circuit diagram, directly burned into the microcontroller can online simulation )

基于VC++的，以操作文件的方式（CreateFile,WirteFile,ReadFile）来操作串口实现的射频卡门禁系统，实现了包括读卡写卡，寻卡防冲突等功能。(Based VC++ in order to manipulate papers (CreateFile, WirteFile, ReadFile) to operate the serial interface of the RF card access control systems, including the realization of the card reader to write, look for cards anti-collision function.)

这是有关pwm的控制，可以控制它周期的长短来控制灯的亮度，还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)

单片机键盘扫描程序 微处理器课程设计 八位抢答器(SCM keyboard scanning procedures microprocessor eight Responder Course Design)
