基于EDA技术中的对LED扫描电路的实验，程序能成功运行，能直接在开发板上看实验结果(EDA-based LED technology to scan the experimental circuit, the program can run successfully, can see directly in the development of on-board results)

与IP核配套的I2C-Master Core，包含了目前主流FPGA芯片的I2C实现，代码包括Altera/Xilinx/OpenCore等公司的VHDL/Verilog/C等。(I2C-Master Core)

/功 能：1.实现与CPLD的通信,从而控制PWM的占空比. 2.实现LCD显示相关信息. // 3.实现对键盘按键的判断和确定相应的操作. 4.实现对电压电流的检测. // 5.实现过载保护功能,电流过大时,切断PWM输出,当排除过流故障后,自动恢复供电 // 6.实现用PID算法跟踪电压,实现稳压输出(/ Function: 1. Achieve communication with the CPLD to control the PWM duty cycle. 2 LCD Display relevant information.// 3. Realize the keyboard keys judgment and determine the appropriate action. 4. Achieve the voltage and current Detection// 5. achieve overload protection, current is too large, cut off the PWM output, when excluding overcurrent fault, automatically restore power// 6. achieve tracking voltage with PID algorithm to achieve the regulated output)
