按键SW101则LED303亮

代码如下

int main(void)

{

 

 

	InitSysCtrl();/*将PLL配置成10倍频1分频，配置系统时钟为120M */

 

	InitKEY();

 

	InitLED();

 

	while (1)

	{

 

		if (GpioDataRegs.GPADAT.bit.GPIO3 == 0)

 

		{

			GpioDataRegs.GPBCLEAR.bit.GPIO44 = 1;

 

		}

		else if(GpioDataRegs.GPADAT.bit.GPIO27 == 0)

		{

			GpioDataRegs.GPBCLEAR.bit.GPIO43 = 1;

		}

		else

		{

			GpioDataRegs.GPBSET.bit.GPIO44 = 1;

			GpioDataRegs.GPBSET.bit.GPIO43 = 1;

		}

 

	}

 

	return 0;
