The processor I am using is the MK22FN256VLH12. A GPIO bit in a Port is configured
as an Input which will interrupt on both edges of the signal.The ExtInt component is
used to configure the interrupts. An ExtInt_Ldd has been built with an Initialization
function, the Interrupt handler, and the GetVal function. I use the GetVal to determine
which edge caused the interrupt.
First the Initialization function in ExtInt_LDD is never called, is this correct?
My main problem is the first time that an interrupt is generated my ISR is entered
at the function's entry point. However, the next interrupt results in the ISR being entered
in the middle of the function.Is this a result of the data structure not being initialized?
What can I do to make this work correctly?
I must have had a brain freeze. What I need to do is have 1 ISR which checks which pin caused
the interrupt and processes accordingly. I apologize for wasted time.
SORRY - The problem description is incorrect. My reply to Robin describes the problem that I am having.
I was relying on Breakpoints that did not trigger.
