board: nRF52 DK
[update - fixed this - see #2]
When I use the following (shortened) code, the LED blinks when I press button 2 but I see no logs. NRF_LOG_INFO() is working in other areas of the code.
It doesn't make sense to me that nrf_drv_gpiote_out_toggle(LED1) gets called but foo does not get set to true.
[#2]
For an extra challenge, when I add the following function call to main (setup pins: sck=2, dout=26), LED1 turns on but pressing button 2 does not actuate the led anymore.
For this problem, I suspect it has something to do with GPIOTE channels, but I can't watch the registers because my vscode cortex debugger is not working right now. I'm not overlapping any pins I believe.
