led1.h

LPC214X_ulink_keil3测试过的没问题280版本.主文件新建几个任务了

//const usigned int  LED1=(1<<28);
//const usigned int  LED2 =(1<<29);
//const unsigned int  LED=(1<<24);          //P1.24控制LED,低电平点亮

void LED_init()
{
//	PINSEL2=PINSEL2&(~0x08);
	PINSEL0=0x00000000;
	PINSEL1=0x00000000;
	IO0DIR|=1<<28;//LED1;
	IO0DIR|=1<<29;//LED2;
}

void LED1_on()
{
	IO0SET=1<<28;
}

void LED1_off()
{
	IO0CLR=1<<28;
}

void LED2_on()
{
	IO0SET=1<<29;
}

void LED2_off()
{
	IO0CLR=1<<29;
}
