Hello,

I am trying to use interrupts on my NanoPi NEO.
I have installed WiringNP. Simple commands works.
But when I tried /examples/isr-osc.c I get: "wiringPiISR: Not implemented".

Is it possible to "unlock" wiringPiISR for NanoPi NEO? Or use any other part of WiringNP for interrupts?

And widely, could you give me any advice about best and simple ways to use interrupts on NanoPi?
My goal is to make simple application which counts interrupts on GPIO and save it on files.
I expect maximum up to 10.000cps, but typically up to 1.000cps.
