false condition if statement getting executed inside ISR
I’m sorry Bernard, My bad.
You were right 
I added a counter to watch how many time the ISR was executed. I noticed that code was interrupted anywhere from 15 to 100 times every time the signal switched. What caused me to believe it wasn’t a bouncing issue was that the exact same code ran perfectly well on my STM32F411 but behaved funny on the F303 Motor Control Board (Obviously because of the speed of operation). I do have debouncing hardware and my scope however doesn’t show any noise at a fair scale. I believe I can’t do much to the hardware.
Is there a way I can control the Interrupt Handler ?
I would like prevent interruption for 1µs after a trigger detection.
