Will EPOLL C or PIGPIO C work on pine64? - dkebler - 02-15-2018
I write in nodejs exclusively and on RPI I use this library to control GPIOs
https://github.com/fivdi/pigpio
This module creates bindings to the excellent PIGPIO C library here https://github.com/joan2937/pigpio
and with it and this i2c bus module https://github.com/fivdi/i2c-bus I can anything on the GPIO bus.
I am sure I can get the PIGPIO C library to compile but will it be compatible with the "Pi2" bus on the Pine64?
If so tada I can use my nodejs code directly from RPI to Pine64 without alteration (well except maybe for some pin number translations as pointed out in other posts????)
If PIGPIO C won't work the same dev has a library that uses EPOLL.
So the EPOLL C should compile but will it work with the PINE64 pi2 bus???

I'd much rather use PIGPIO C library as I have discovered it's much more robust than the EPOLL
What are my options here?
I understand I can just write sysfs calls directly in nodejs but I've discovered that's not very robust.
One thing I definitely do frequently on the Pi is use pins as interrupts and that is easy with PIGPIO or EPOLL. As far as I understand if only using sysfs then you have to manually poll the pin state in your code continuously (in nodejs that would be setInterval) looking for a state change (which is really not robust at all).
