了解 CAN 总线通信原理，实现利用 CAN 总线完成通信 在进行实验的时候，需要将两块开发板连接 USB 线进行充电，因为利用 CAN 总线进 行通信需要有较高的驱动能力。(Learn CAN bus communication theory, to achieve complete CAN bus communication when carrying out the experiment, you will need two development boards connect the USB cable for charging, because the use of CAN bus communication requires a higher drive capability.)

PSCAD differential relay simulation, can be used for educational and for real substation simulation

STM32F407信号发生器输入一个正弦波，AD采样，DA输出，系统频率应该是输入的波形的频率的10倍以上保证输出波形的完整性，系统的输出频率可以使用示波器测试出。(Stm32f407 signal generator input a sine wave, AD sampling, Da output and system frequency should is 10 times the frequency of the input waveform to guarantee that the above output waveform of integrity, the output frequency of the system can use oscilloscope to test out. )

iic接口的程序，可以用于f149单片机(iic interface procedures can be used F149 microcontroller)

说明：  基于WiFi的温湿度监测与显示，(1)主控芯片采用STM32系列单片机、数字温湿度度传感器DHT11、WiFi模块ATK-ESP8266； (2)通过数字温湿度度传感器DHT11采集数据； (3)将数据通过WiFi模块在电脑上进行显示。(Temperature and humidity acquisition)
