这里有很多我自己做的凌阳单片机源程序

#include<spce061a_chf.h>
unsigned int count=0;//会不会每次进入中断程序都初始化为0？？？？？？？？？
extern temp;
extern time;
extern key_scan();
unsigned int showval[4]={1,2,1,0};//要显示的值
unsigned int a[16]={0x0011,0x00d7,0x0049,0x0045,0x0087,0x0025,0x0021,0x0057,0x0001,
0x0005,0x0003,0x00a1,0x0039,0x00c1,0x0029,0x002b };//段选码,a-IOB7,dp-IOB0
unsigned int b[4]={0xf7ff,0xfbff,0xfdff,0xfeff};//位选码*/低电平点亮
void IRQ6(void)__attribute__((ISR));
void IRQ6(void)
{
	asm("int off");	
	if(*P_INT_Ctrl==0x0002)
		*P_INT_Clear=0x0002;//若是TMB1中断就清中断
		else
		{		
			count++;
			time++;			
	 		if(count==4)
	 		{	 			
	 			count=0;
	 			temp=key_scan();
	 			time=0;						
				*P_IOB_Data=a[showval[3]];
				*P_IOA_Data=b[3];
	 		}	 				
			*P_INT_Clear=0x0001;			
			*P_IOB_Data=a[showval[count]];				
			*P_IOA_Data=b[count];		
		}
		asm("int irq");
}
