If all you wanted was single mode it would be easy enough to use STAR momentary with only 0,255 setup in the modes (off and 100%). That would achieve the stated goal but probably isn’t what priest77 meant.
Apparently STAR Momentary 1.4 adds a mode that might do what priest77 is asking for, I don’t have a documentation link but I guess it’s probably discussed somewhere in the 100-post range of 424 through 524 in the STAR Firmware by JonnyC - Source Code and Explanation thread. Here is the direct link to the actual source code for 1.4.
I think a more permanent solution should be easy to implement. That might actually be something I’d like to use. I’ll have to think about it a little bit. Something like:
- Short press for on/off
- Long press from “on” to advance modes - with offtime memory ideally.
- Long press from “off” - special function. Compile time option for: 1. direct high 2. direct low 3. unlock disco modes 4. no action
