led.c

可以实现44B0的底层所有通信

#include <string.h>
#include "..\inc\def.h"
#include "..\inc\44b0x.h"
#include "..\INC\44blib.h"
#include "..\inc\led.h"

//LedNum=0，则同时对4个LED操作
//LedNum为1~4的时候，分别进行操作
void Led_Display(U8 LedNum,U8 LedStatus)
{
	//PC1,PC2,PC3 High available
	U16 temp;
	if(LedNum==0)
		{

				temp=0x1e0;
			else
				temp=0x0;
			rPDATF=(rPDATF & 0x1f)|temp; // rPDATF&0x1f->rPDATF=0x1ff--edited by tianjh 05.03.19
		}
	else
		{
			temp=0x10<<LedNum;
			if(LedStatus==0)
				rPDATF=(rPDATF & 0x1e0)|temp;
			else
				rPDATF=(rPDATF & 0x1e0)&(~temp);
		}
