Hi TI:
I am unable to get a GPIO Callback running with the TI-RTOS driver.
This is pretty easy stuff; but, I'm not seeing what I am missing.
I have a similar function running fine without using the TI-RTOS GPIO Driver.
The Output at the bottom shows that I can clearly read the state of the Pin.
I just can not get the Interrupt to fire in order to increment a global counter.
Since I could not find an example of a GPIO Driver using an Interrupt,
I'm wondering if I'm missing in the DK_TM4C129X_initGPIO(void) routine.
Any help would be greatly appreciated.
Thanks
Rick
