Part Number:EK-TM4C1294XL

Tool/software: TI C/C++ Compiler

Hi all,

currently working on tm4c1294xl eval kit, currently iam working on project were i need to monitor input signal for every second if any change is there i need to perform neccesary action.

i tried with instruction  i32Val = GPIOPinRead(GPIO_PORTE_BASE,GPIO_PIN_2) before starting the timer later on on i checking changes by if(i32Val == GPIOPinRead(GPIO_PORTE_BASE, GPIO_PIN_2))

by setting timer for every 1 second but it is not working , can any guide regarding this issue
