电子负载原理, 负载效应讲的很好，很多恒压源，恒流源，恒阻源模型(The principle of electronic load, load effect speak well, a lot of the constant voltage source, constant current source, constant resistance source model)

PIC单片机I2C功能 电后,LED闪亮,单片机硬件I2C读写24LC64,LCD显示读出数据,LED5运行指示(PIC microcontroller I2C function after power, LED flash, microcontroller hardware I2C read 24LC64, LCD display read out, LED5 operating instructions)

PMSM 电机FOC控制单片机程序，SPANSION Cortex-M4 单片机(PMSM FOC control sample code)

stm32的一些程序，其中包括一路pwm生成，一路是pwm捕获，一路接受一路捕获(Then use the display show the duty ratio and frequency )

C51下温度传感实验 检测温度，并用数码管显示出来 。(C51 experimental testing temperature of the temperature sensor and a digital control display.)

单片机入门推荐实验可以帮助大家快速入门，有大量代码，可供调用(experiment for 51MCU)

说明：  利用DHT11采集温湿度，利用中断，每2秒采集一次，并利用串口传输至上位机系统(use DHT11 to get temperature and humidity)

stm32硬件SPI方式控制ADS1247采样驱动程序(stm32 hardware SPI driver controls the ADS1247 sampling)

模型为新能源汽车制动能量回收模型。根据加速踏板，SOC等来确定制动扭矩。(The model for new energy automobile braking energy recovery.According to the accelerator pedal, SOC and so on to determine the braking torque.)

说明：  亿光EL817光耦的应用资料，我已经在电路板上使用了模块，很好用，可以用在低速开关领域(100 million light EL817 optocoupler application information, I have used the modules in the circuit board, well used, can be used in the field of low-speed switch)
