双馈风电机组的PSCAD模型，是通用模型，有助于帮助解决双馈风电机组建模问题(PSCAD doubly-fed motor model)

Battery management system for up to 15 Li-ion cells based on bq76940 or bq76930 IC from Texas Instruments

说明：  法国Humirel公司新一代HTU21D温度和湿度传感器驱动(The Humirel HTU21D is a new generation of temperature and humidity sensors)

说明：  轮流点亮P1口所接LED并循环显示，间隔0.5s(Turn on the LED connected to P1 port in turn and display circularly, with an interval of 0.5s)

用TM1652基于C51做的一个简单的6位显示驱动，方便移植。(TM1652 based on C51 to do a simple 6 bit display driver, easy to transplant。)

使用51单片机和cc2530模块组成的路由器程序，可以实现收发和存储功能(51 machines use a single product and get the router module cc2530 program)

待检测pcb板和标准pcb对比，然后对待测pcb腐蚀及膨胀处理，进行缺陷标注显示图像并输出焊盘缺失数，导线缺失数，短路数等。所以源图像均有，并再次测试无误，可以直接运行。(To be detected and the standard pcb board pcb contrast, then treat corrosion test pcb and the expansion process, defect labeling displays images and outputs missing number pad, missing a few wires, short circuit and number. So were the source image, and test again correctly, you can run directly.)

simulation of induction motors and how to drive it in industrial

可实现用stm32串口读取mpu6050数据(Mpu6050 data can be read by stm32 serial port)
