Visualizing push button interrupt in a logic analyzer

[morpho]

Is there a way to get the signals of the interrupt for a push-button/interrupt from the pin_change_int example in a logic analyzer software tool?

Basically i'd want to visualize things that take place when a button is pressed as well as how the interrupt is fired right away. There isn't any PIN in the header that's corresponding to the push button that could be connected to the channel of logic analyzer?

That depends on whether you use a button library with SW de-bouncing or not.

I'm using the example `pin_change_int` which doesn't seem to use debouncing, does it?

Nope, so it should suit your needs. 

Reading the example description:
"The application starts with configuring the pins and configuring GPIOTE to give an interrupt on PIN_IN change. The interrupt handler toggles PIN_OUT (LED 1) when PIN_IN (button 1) is pressed or released."

See fig1 in the DK's Connector interface chapter. LED1 is connected to p0.13, I believe it's active low.

I see. So P0.11 really is connected to Button 1 and that's where the Channel pin of the logic analyzer would go.

A follow up: 

where are we defining whether the interrupt would be triggered at the falling edge?
