Used on an Onion Omega2 Plus to read one json item of 0 and 1s from a url containing: [{"content":"0001100000001000","columns":8}]


  • opkg update
  • opkg install nodejs
  • opkg install node-oled-exp
  • opkg install npm
  • npm install request -g

Option to add this to the /etc/rc.local file to start the script on boot:

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.

node /root/oled-node.js

exit 0

Pending Goals:

  • add an sd card to my Onion Omega2 Plus, I ran out of space
  • get git auth working on my microcontroller, user posts were not helpful
  • show more than one pixel image, pages on the Omega were not what I had expected (they are rows)
