说明：  使用正点原子的精英板/战舰板，使用带FIFO的ov7725 实现普通二值化(Ordinary binarization using the elite plate/warship plate with punctual atoms and ov7725 with FIFO)

ZigBee联网，多传感器数据无线采集,CC2530,协调器使用串口将数据传回上位机显示(ZigBee networking, wireless multi-sensor data acquisition)

说明：  控制说话的内容输出,因为现在基本上都需要用到语音控制模块，在学校公司家庭等等。语音播放控制，家庭智能锁开门，门禁系统控制。(Control the content of the output, because now basically all need to use voice control module, school, company, home and so on. Voice playback control, home intelligent lock door, access control system control.)

说明：  STM32F103VET6用LCD画坐标轴(Drawing coordinate axes with LCD in STM32F103VET6)

本实验利用STM32F407开发板连接TFTLCD模块，实现TFTLCD模块的显示，下载成功后，通过把LCD模块插入TFTLCD模块接口，按下复位之后，就可以看到LCD模块不停的显示一些信息并不断切换底色。同时该实验会显示LCD驱动器的ID，并且会在串口打印（按复位一次，打印一次）。(This experiment uses STM32F407 development board to connect TFTLCD module to realize the display of TFTLCD module. After downloading successfully, by inserting the LCD module into the interface of TFTLCD module, after pressing reset, we can see that the LCD module keeps displaying some information and changing the background color. At the same time, the experiment will display the ID of the LCD driver and print it on the serial port (press reset once, print once).)

pid温控c程序算法，这是一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算，而将所有参数全部用整数，(pid temperature control algorithm c program)
