TM4C1294NCPDT: timer1 input capture，cannot run into the interrupt

Hi,
Which timer do you want to use?

In your code you have the below two lines that setup the TIMER0 instead of TIMER1. Please change to TIMER1_BASE if you want to use TIMER1.
TimerPrescaleSet(TIMER0_BASE, TIMER_B, 24);
ROM_TimerLoadSet(TIMER0_BASE, TIMER_B, 624);

Also the line GPIOPinTypeGPIOInput(GPIO_PORTA_BASE, GPIO_PIN_3) should be removed.

Vendor's Charles excellently identified your code 'irregularities.'

However - as you've noted, 'Failure to enter the (assumed) Timer1 Interrupt' - should you 'NOT' have provided (some/slight) mention (ideally a code listing) of that 'Yet to be entered' Timer1 Interrupt?

In addition - that Timer1 Interrupt must appear properly w/in the 'Start-Up file' (while 'name matching' (w/in Start-Up and your other code)  - or be 'Registered' - to insure that it is recognized.    (Recognition precedes Entry!)

thanks for your advice
i fell sorry that i paste the wrong code here.
according to your advice , i rectify my code, as follow:
void Timer1_Capture_Config(void){
SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMER1);

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA);
SysCtlDelay(200);
GPIOPinConfigure(GPIO_PA3_T1CCP1);
GPIOPinTypeTimer(GPIO_PORTA_BASE, GPIO_PIN_3);
TimerConfigure(TIMER1_BASE,TIMER_CFG_B_CAP_TIME_UP|TIMER_CFG_SPLIT_PAIR);
TimerControlEvent(TIMER1_BASE,TIMER_B,TIMER_EVENT_POS_EDGE);
ROM_TimerLoadSet(TIMER1_BASE, TIMER_B, 32768);
IntEnable(INT_TIMER1B);
TimerIntEnable(TIMER1_BASE, TIMER_CAPB_EVENT);
IntMasterEnable();
TimerEnable(TIMER1_BASE, TIMER_B);

}


and Timer1 Interrupt appear properly write the 'Start-Up file' , but i still cant run into my interrupt.
is any other problem in my Config?

thanks for your advice!
the 1kHz square wave are provided for the PA3, and for testing the TIMER1 , i just configure the timer1 in the main function. and my 'Start-Up file' is right. i suppose that mt config is wrong.
