If anyone is trying to use their Omega 2 with Blynk the edit required to use some digital pins directly is:
Locate blynk-node.js in /usr/bin/blynk-library
Around line 329 change
var Gpio = require('onoff').Gpio;
to
var Gpio = require('/usr/bin/onoff-node/onoff').Gpio;
Some digital pins means pins that are common to the original Omega and the Omega 2 (or 2+) until such time as the pin definitions are updated.
@vshymanskyy Onion have a potentially useful browser tool to control GPIO’s that will look something like this when it is updated and the pins match the image of the MCU.
Currently if you try to update a GPIO, via the browser, that is also being controlled by Blynk the connection to Blynk will drop with a js error. Would be nice one day for it all to work together.
