So here it is: Anduril: implement quick aux LED on/low switching, see description at the top · GitHub, implemented as a diff patch against TK’s latest and greatest multi-channel branch rev 721.
The above is tested and working perfectly on both my Wurkkoses (TS10 and FC13), and I don’t see a reason for it not to work in every flashlight supported by @Toykeeper’s multichannel branch revision 721. In fact I’ve changed to it as my “daily driver”[1] firmware on both my lights.
In case you don’t want to patch/configure/compile a new hex from the diff above, tell me your flashlight model number (or send me your cfg-brand-model.h file) and I will do it for you and send you the hex.
Hope that helps!
