Problem on ADC TM4C1294

Hello,

I'm having some problemson the ADC of TM4C1294

The ADC can not go to the interrupt, I have tested many times. I considered many codes on this forum and followed them. I also changed the sequence from 0 to 3 and ADC0 to ADC1. However, the ADC's interrupt didn't occur.

May be I could be lacked anywhere. Can anybody help me with this. Thanks so much.

In the startup file:

    ADC0SS3IntHandler,                      // ADC Sequence 3

Here is my code:

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "inc/hw_ints.h"

        UARTprintf("trigger ok \n\r");

    }
}

    UARTprintf("having interrupt \n\r");
    ADCSequenceDataGet(ADC0_BASE,3,ADC0Value); // Get Data from ADC and store it in ADC0Value
    if (ADC0Value[0] > 0) UARTprintf("having connect\n\r");
