Forum Post: RE: EK-TM4C1294XL: Unusually Large Interrupt Latency
cb1's answer is excellent! A few more pointers: - Be careful with specific interrupt clearing, such as GPIOIntClear(GPIO_PORTF_BASE, GPIO_INT_PIN_0); - it is wiser to read the interrupt mask, and then...

Just in case someone might be interested, the problem lies where hour * 3600. If hour 18 then somehow resulted value of seconds is 65536 smaller than correct value. I believe this is something related...

Rather than use a if statement for every interrupt vector in the library a more maintainable solution might be to use a macro such as RUN_TIME_RESOLVE_INT: #include #include #include #include #include...
