说明：  stm32f407 ucGUI port

能利用stm32f4+ov5640去识别黑色(Recognition of Black Using stm32f4+ov5640)

stm32无刷电机驱动程序，所适用于MOS管所搭分立元件，是自平衡车的程序(stm32 brushless motor driver, which is suitable for the ride MOS transistor discrete components)

以前电子竞赛时写的M3 ARM控制TFT液晶显示正弦波波形可以连贯的左移，没有闪烁感，我还写了一个也是正弦波左移，只不过有一点闪烁，我也上传了，你们需要可以找一下！(Writing contest before the electronic control M3 ARM TFT LCD sinusoidal waveforms can be coherent left, no flashes, I also wrote a sine wave is left, just a little flicker, I also uploaded, you need to be able to Get it!)

PIC模拟两路PWM输出,采用中断加按键10MS扫描可调占空比功能,解决模拟PWM调占空比冲突(PIC simulation of two PWM outputs, with adjustable scan interrupt duty cycle plus function keys 10MS resolve conflicts analog PWM duty cycle modulation)

正点原子STM32F103精英板蜂鸣器例程(Punctual Atom STM32F103 Elite Plate Buzzer Routine)

通过串口采集OV7725摄像头像素数据，可发送至PC端进行解析。(Through the serial port to collect OV7725 camera pixel data, it can be sent to the PC terminal for parsing.)

说明：  stm32板上的SD卡的使用，通过SPI接口控制SD卡，不涉及文件系统，只是简单的实现底层读写接口，编译环境为IAR。(stm32 board SD card, SD card through the SPI interface to control the file system does not involve simply the realization of the underlying reader interface, IAR compiler environment.)

用液晶1602 来显示r日期 年月日和分和秒计时器(ｕｓｅyejing 1602 to display thedate and the time mintate ang scend)

实时时钟芯片DS1305用AVR90usb1287显示读秒的测试程序，对初学单片机的接触实时时钟的很有帮助(The test program for real-time clock DS1305 with AVR at90usb1287, very helpful for learner of AVR microcontroller )
