**ERROR** Invalid pin number, "unusable" pins in `new-gpio` (IRQ version)? How to make them accessible.
I found that some pins, by some reason, staying inaccessible (
**ERROR** Invalid pin number, GPIOAccess::isPinUsable returns
new-gpio), despite of that I made them as "inputs" with
fast-gpio. Is there any way to make them "free"?
fast-gpioworks just fine. But I would like to utilize IRQ instead of permanent polling.
