I have implemented WiringNP on my NanoPi NEO according to FriendlyARM wiki:
http://wiki.friendlyarm.com/wiki/index. ... direct=no=

When I test example isr.c or isr-osc.c (or any other code with wiringPiISR function) the following fatal error comes up:
wiringPiISR: Not implemented

I got the same result when trying use gpio isr. That is a limitation of wiringNP. GPIO isr handler works on other pi platform? Is there any plan to support that?

I looked to the code at https://github.com/friendlyarm/WiringNP ... wiringPi.c : there is no support code for event/interrupt mode of the GPIO. The support code has been there in the past, but major wiringPi.c procedures have been siimply shrinked to allow a quick delivery. The library looks useless in this state.

I found the original code for the Orange PI at https://github.com/zhaolei/WiringOP/blo ... wiringPi.c and I m pretty sure this code would work great with minor adaptation to the nanopi.

I'm interested aswell, any news on the topic?

I too was disappointed to learn that interrupts are not supported. I am trying to find a (relatively) simple method of detecting fan speed - other than meltdown of board. Am seeking path to use interrupt to measure tach output from fan in Node Red and this seems the place to start. Someone correct me if not.

I assume that once it works for NanoPi NEO2 it will also work for NanoPi NEO Plus2. I have both and have more projects that could use this capability.
