There are any NodeJS Library for manage GPIO?

[Laurence HR]

Hi, I know that exists official python library for manage GPIO.
I would like a Node Library for manage gpio, and get values from a temp sensor or similar, because I have a Cayenne library (in node) for send values to dashboard, but I need read from onion.
Thanks

Hi!

There's a Johnny Five IO plugin: https://github.com/gunderson/omega2-io (i love J5 )

It "simply" wrap fast-gpio exec, for ex: require( 'child_process' ).spawn( 'fast-gpio', params );

If you don't want to use J5, you can code you own js driver (see https://github.com/gunderson/omega2-io/blob/master/lib/omega2.js#L97)

(I haven't test it for now)

Thanks @Balda , and with Johnny Five plugin, JF is running in Omega? I only hear about that using Arduino, but in that case running in PC the main code. I will try

I actually did not want to use the spawn function, I was expecting an official library, but for the moment I do not have another option hehe

I haven't found any official NodeJS for the GPIO.

But I did come across this last night: https://github.com/OnionIoT/onion-gpio-sysfs/blob/master/python/onionGpio.py

It should be possible to create a library that could control the GPIO using the filesystem entries like this python code.
