Error in input mode of cc3200 GPIO [Copy Link]

Use the DO of the photoresistor to output high and low levels, read the level value with the input of GPIO, and control the light on and off. However, the desired phenomenon is still not found. Moreover, Mingming turned off all the lights at the beginning, but it is still on. Here is the code

//control the input
void ReadDeviceConfiguration()
{
     unsigned int uiGPIOPort;
     unsigned char pucGPIOPin;
     unsigned char ucPinValue;

     GPIO_IF_LedOff(MCU_ALL_LED_IND);

     while(1){
         //Read PIN1 ucPinValue
     GPIO_IF_GetPortNPin(GPIOIN,&uiGPIOPort,&pucGPIOPin);
     ucPinValue = GPIO_IF_Get(GPIOIN, uiGPIOPort,pucGPIOPin);

     console.log(ucPinValue);
     //LIGHT slow
     if(ucPinValue == 1)
     {
         GPIO_IF_LedOn(MCU_RED_LED_GPIO);
     }
     //light high
     else
     {
         GPIO_IF_LedOff(MCU_RED_LED_GPIO);
     }

     //Enable GPIO Interrupt
     MAP_GPIOIntClear(GPIOA0_BASE,GPIO_PIN_7);
     MAP_IntPendClear(INT_GPIOA0);
     MAP_IntEnable(INT_GPIOA0);
     MAP_GPIOIntEnable(GPIOA0_BASE,GPIO_PIN_7);

     ucPinValue=0;
     }

}


int
main()
{
//Set vector table base Set the base address of the interrupt vector table, allow interrupts, and initialize MCU
    BoardInit();

    // Power on the corresponding GPIO port B for 9,10,11.
    // Set up the GPIO lines to mode 0 (GPIO)
    PinMuxConfig();

    GPIO_IF_LedConfigure(LED1|LED2|LED3);

    GPIO_IF_LedOff(MCU_ALL_LED_IND);

    ReadDeviceConfiguration();

    return 0;
}

Thanks~

Regardless of the input status, the control light turns on and off. See if it can be realized, but it can't. There is a problem with the initialization configuration. Go to modify the initialization. If it can be realized, check the input configuration and control output logic.

First, measure the output level of your IO, and then look at the lighting mode of your hardware LED lamp, whether the IO should be turned on for high level or low level.
