DSP2833X实验_点亮第一个LED_GPio结构

GPIO结构框图：

void LED_Init(void)
{
    EALLOW;
    SysCtrlRegs.PCLKCR3.bit.GPIOINENCLK = 1;// 开启GPIO时钟

    GpioCtrlRegs.GPBMUX2.bit.GPIO60 = 0; //设置为通用GPIO功能
    GpioCtrlRegs.GPBDIR.bit.GPIO60 = 1; //设置GPIO方向为输出
    GpioCtrlRegs.GPBPUD.bit.GPIO60 = 0; //使能GPIO上拉电阻

    GpioDataRegs.GPBSET.bit.GPIO60 = 1;//默认输出高

    EDIS;
    }

#define LED1_OFF        (GpioDataRegs.GPCSET.bit.GPIO68=1)
#define LED1_ON            (GpioDataRegs.GPCCLEAR.bit.GPIO68=1)
#define LED1_TOGGLE        (GpioDataRegs.GPCTOGGLE.bit.GPIO68=1)
