isr.c

iic总线控制led,我就这是根据linux下面的驱动自己改的

#include "lib.h"
#include "/inc/macro.h"
#include "reg2410.h"
void IIC_IrqHandler(void);

void ISR_IrqHandler(void)
{
	U32 IntOffSet = rINTOFFSET; 
	
	if(IntOffSet==27){
		IIC_IrqHandler();
	} 
	else{
		rSRCPND = rSRCPND;
		rINTPND = rINTPND;
		return ;
	} 
}
