onion-oled-js is a JS library that exposes a collection of functions that wrap the oled-exp executable that controls the onion omega OLED display. This library is promise oriented and aims to provide higher level functionality in the future.
npm install onion-oled-js
var OLEDExp = require('onion-oled-js').OLEDExp;
OLEDExp.powerOn()
.then(OLEDExp.initialize)
.then(() => OLEDExp.write('first thing', 0, 5))
.then(() => OLEDExp.write('second thing too', 1, 1))
.then(() => OLEDExp.cursor(3, 0))
.then(() => OLEDExp.write('really really really really really really long sentence'));
