室内报警系统（51单片机实现）,实现室内温度监测，室内气体异常监测，室内安全监测！(Indoor alarm systems (51 MCU) realize the indoor temperature monitoring, anomaly monitoring indoor air, indoor security monitoring!)

说明：  C51 DOS与WINDOWS环境下，开发MCS51系列机器的VFD（等离子显示器）的驱动程序(C51 DOS and Windows environment, the development of MCS-51 series machines VFD (PDP) driver)

使用stm32f407单片机的CAN通信控制驱动电机，并且该程序可以通过红外遥控(CAN communication with stm32f407 MCU is used to control the driving motor, and the program can be controlled by infrared remote control.)

说明：  基于无功补偿控制器的MODBUS实现，用于高低压无功补偿控制器及其应用算法(Realization of Modbus based on reactive power compensation controller)

说明：  stm32制作的示波器资料，涉及FFT变换的算法。(The data of oscilloscope made by STM32 involves the algorithm of FFT transform.)

说明：  单片机 LCD12864显示演示程序(Singlechip LCD12864 show demo)

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).)

说明：  code for events which is there.
