I'm facing with problem.I don't know why it cant't operation

}
void Tem_ISR(void)
{
ADCIntClear(ADC1_BASE,1);//clearn flag interrupt
ADCSequenceDataGet(ADC1_BASE,1,(uint32_t *)&Temp);//force type for data read
//the date was read form sensor is digital type.should change for number.
TempC=(1475 - ((2475 * Temp[0])) / 4096)/10;//total vref- +((vref+ -vref-)/4096)*Data
}
void main (void)
{
// Configure clock 40 MHz
SysCtlClockSet(SYSCTL_SYSDIV_5 | SYSCTL_USE_PLL | SYSCTL_OSC_MAIN | SYSCTL_XTAL_16MHZ);
config_TempSensor();
while(1)
{
ADCProcessorTrigger(ADC1_BASE, 1);
}
}
the tempC=0 any time.
Thanks for your supports.
