//PID的数据结构
struct PID {
int   gpwm;			//跟踪值
float Proportion;	//比例常数 Proportional Const
float Integral;  	//积分常数 Integral Const
float Derivative;	//微分常数 Derivative Const
int LastError;   	//Error[-1]
int PrevError;	//Error[-2]
float SumError; 	//Sums of Errors
float P;
float I;
float D; 
}pid,*Ppid;


//LCD显示的相关字符串
bit clear;							//清屏标志
bit waitin;							//等待输入标志
unsigned char outu_list[5]="00.0";	//输出电压字符串
unsigned char outi_list[5]="0.00";	//输出电流字符串


//ADC测量的数据
int outu;			//输出电压值,扩大10倍保存
int outi;		 	//输出电流值,扩大100倍保存

//电源状态标志
bit flagpower;		//电源开关标志
bit flagguo;		//过载保护标志
bit I_Oput;			//输入/确定标志,1为输入状态
bit error;			//输入错误标志
char buff[2];		//按键记录
unsigned char inu;	//按键输入电压值,扩大10倍后再赋值给fixoutu
char putcoun=0;		//输入数字个数
int  fixoutu;	//输出电压给定值

//保护状态相关变量
unsigned char timer;		//用于定时1.8s计数用,开始数据为80



//ADC转换查表
