Suggestions for content:

  • I have difficulties to track the flow of data from it is fetched from the USB Pro until it is printed to the console by the app lla_usbpro. Some diagrams over the structure and data flow diagrams, or text that gives a good overview would be nice
  • What is the structure of the plugins?
  • What is the interface between the LLA core and LLA plugins?
  • What is the interface between the LLA core and other apps/clients to LLA like QLC?
  • What is it with the hidden web server?

How is functionality split between the usbpro plugin and the example program?
