LJ Laser Server v0.8.1
Inspiration for new WebUI icon menu :
https://codepen.io/AlbertFeynman/pen/mjXeMV
Laser server + webUI servers (ws + OSC)
- get point list to draw : /pl/lasernumber
- for report /lstt/lasernumber /lack/lasernumber /cap/lasernumber
- A nice ws debug tool : websocat
- a "plugin" is a generator that send points to LJ. Plugins if they have an open OSC port can be checked and restart if in the same computer.
Todo :
- If no plugin ping is not received, restart the plugin.
- upgrade to python3
All used ports:
8002 OSC incoming
9001 WS communication with WebGUI
Plugins OSC Ports (see LJ.conf)
