A small application to drive LED matrix displays, such as the pimoroni unicorn, from nodejs. My intention is to create a digital graffiti/guestbook system.
|

|
|
Make sure you are on a recent nodejs version. Raspbian has an old version. Use nodesource ;).
|
|
|
|
Also, use a decent modern browser. I wrote recent syntax, so probably works best in Chrome 62+. Firefox is known to have some issues, Edge works, Safari is a PITA. Just wait for your browser to play catch up then with recent standards. If you dislike Chrome, you can put this trough Babel. But you're on your own there.

Copy config.example.json to config.json and pick a driver + display size.
|
|
|
|
execute:
|
|
|
|
npm install
|
|
nodejs pixdisp.js
|
|
|
|
Navigate to http://localhost:8080/
