I overhauled the LED Ring Controller. It is now available as Windows Service. It runs in the background and can be started automatically at system startup.
A new function has been added to the LED ring firmware. It now supports a free running automatic countdown function. This allows to use countdown in Breeze or Darkroom Booth.
To support applications that can only call commandline functions, a helper application has been added.
The latest version of the software and firmware is now available on my website.
