使用STM32F4+usb3300实现虚拟示波器,支持使用外部ADC模式，也就是使用AD9280芯片，最大采样率可达30MSPS.(STM32F4+usb3300 implementation of the virtual oscilloscope, support the use of external ADC mode, that is, the use of AD9280 chip, the maximum sampling rate of up to 30MSPS )

nrf2401 发射机和接收机双向同步跳频，在35个信道上来回跳 超级防干扰(Nrf2401 two-way synchronization of fh transmitter and receiver, jump to and fro on the 35 channels Super tamper-proof)

关于一个滑块显示的程序，可以通过滑块调整实现各种功能(About a slider and its function)

红外报警程序，利用红外发射实现自动报警，当有目标靠近，发出蜂鸣名声(Infrared alarm program)

说明：  时钟芯片PCF8563 C51程序，本人测试通过(Clock chip PCF8563 C51 program, I test through)

简单的鼠标控制程序，可修改控制鼠标点击等(Simple mouse control program)

测试程序ATMEGA8LED的灯亮和灯灭(Test ATMEGA8LED lights turn on and off)

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)

主要是完成Listctr的封装,和对于xlistctrl 的一个实例程序 (The main package is completed Listctr)
