mc8051代码，里面功能齐全，调试方便(mc8051 code, inside a full-featured, easy debugging)

/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)
