PIT Build Error on DEVKIT-5744P('TIMER_LED_IN_A' undeclared (first use in this function))

Question asked by Martin Zhang on Jul 11, 2018

Does any one can help me?

I want to make a demo on DEVKIT-5744P, which a led's state can  toggle at 1s(1s light on, and then 1s light off) . But it can not  build successfully. It seems that my state A is not known by PIT ISR.
