说明：  通过温度传感器获得温度值，并设定温度值，在温度值大于设定值时，单片机驱动风扇，降温。(The temperature value is obtained by temperature sensor, and the temperature value is set. When the temperature value is greater than the set value, the single chip computer drives the fan to cool down.)

用proteus仿真实现BLDC无刷直流电机的控制，目前仅工作于开环状态，可以参考一下。(BLDC brushless DC motor control is realized by Proteus simulation. At present, BLDC brushless DC motor only works in open-loop state, which can be referred to.)

一个简单的贪吃蛇程序，asdw键控制蛇上下左右，会一直加速，可以保存最高记录，可以通过改很少的参数改变界面大小、蛇的初速度与加速度。(A simple Snake program, asdw control the snake up and down, will always speed up, you can save the record, you can change a few parameters change the interface size, snake initial velocity and acceleration.)

基于stm32 的ov7670模块，带FIFO的(Ov7670 module based on STM32, with FIFO)

说明：  51网站上下载的利用蓝牙控制小车和舵机的程序，可实现蓝牙控制舵机(The program downloaded from website 51 that uses Bluetooth to control the car can realize Bluetooth to control the car.)

adc0832.h 模块程序,自写模块,容易调用.(adc0832.h module program, since the write module, easy call.)

基于STM32的I2C实验，调试成功，可移植使用(Based on the STM32 I2C experiment, the successful commissioning, portable use)

基于430单片机实现的AD9852信号发生器。可以实现键盘输入频率选择，也可实现频率范围内扫频，功能菜单由12864显示(the AD9852 signal productor based on 430 MCU ,the frequency of signal can be controled by 4*4 keyboard .)

基于CP2200的TCP/IP驱动程序,是嵌入式网络连接的最简单方案(The CP2200-based TCP/IP drivers, embedded network connectivity is the most simple program)

基于51单片机的超声波测距模块使用，使用HC-SR04模块，定时器测量回波长度(Ultrasound Ranging Module Based on 51 Single Chip Microcomputer)
