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)
