38.c

这里有很多我自己做的凌阳单片机源程序

//将38kHz的方波做成子程序的形式
#include<spce061a_chf.h>
unsigned int uiData=0xffff;
void khz_38();
void main()
{
	//unsigned int i;
	asm("int off");	
	Set_SystemClock(0x00f8);
	
	Set_IOA_Dir(0xffff);
	Set_IOA_Attrib(0xffff);
	Set_IOA_Data(0xffff);
	
	//*P_INT_Ctrl=0x0008;
	//asm("int irq");
	
	while(1)
	{
		Watchdog_Clear();
		khz_38();
	}
}
void khz_38()
{
	unsigned int i=5;
	uiData^=0xffff;
	while(i--)
	{
		Watchdog_Clear();
		Set_IOA_Data(uiData);
	}
}
