利用stm32f4采集ov2640摄像头图像，将图像二值化处理后，得到黑白图像，再经过算法，识别出图像的形状，目前可以识别：正方形、三角形、圆形(Using stm32f4 to capture ov2640 camera image, the image two value processing, get black and white images, and then through the algorithm to identify the shape of the image, can now identify: square, triangle, round)

1.传感器适用于土壤的湿度检测； 2.模块中蓝色的电位器是用于土壤湿度的阀值调节，顺时针调节，控制的湿度会越大，逆时针越小； 3.数字量输出D0可以与单片机直接相连，通过单片机来检测高低电平，由此来检测土壤湿度； 4小板模拟量输出AO可以和AD模块相连，通过AD转换，可以获得土壤湿度更精确的数值； 使用STM32驱动时，一般使用ADC读取其模拟量输出，以gokit stm32f103c8t6为例；">

非常不错的一款STM32开发板资料。 含原理图、用户手册、各类例程：USB虚拟串口、TFT显示例程、U盘例程、TCP通信、uCOS例程、MP3解码、步进电机例程等。有KEIL和IAR两套例程。 (A very good STM32 development board. Including schematics, user manual, all kinds of routines: USB virtual serial ports, TFT display routines, U disk routines, TCP communication, uCOS routines, MP3 decoding, stepper motor routines and so on.)

ARM7 CAN收发代码 已经测试成功(CAN COMUNICATION!)

C++ 编写的string类库，并实现string的各项函数操作。(string function)

ARMSYS6410(V1.1),立宇泰6410开发板随板关盘里的资料，扩展板的原理图，我买的板子(ARMSYS6410 (V1.1), Li Yu-tai 6410 development board with the board off the data plate, expansion board schematics, I bought the board)

说明：  对OLED进行显示，分别用IIC的以及SPI的来进行测试(Display OLED and test it with IIC and SPI respectively)

正点原子F429的本身CAN口例程太过简单；为此做了一点改进，优化了发送和接收效率。(The CAN routine of the punctual atom F429 is too simple; some improvements have been made to optimize the efficiency of sending and receiving.)
