Just a quick note about the firmware… It’s not mine. I don’t have answers about it. The manual for Bistro is not the correct documentation for the D80v2.
The D80v2 uses code called Bistro OTSM, which is Lexel’s version of Bistro HD, which is Flintrock’s nearly complete rewrite of Bistro. It seems to mostly copy the UI for Bistro, but there are some differences. And the exact code details aren’t really known since Lexel hasn’t provided the D80v2 source code yet.
Flintrock left BLF a while ago, but I have Flintrock’s published version of Bistro HD in my firmware repository and I don’t think Lexel changed it much. So one of its build targets should be pretty similar to what’s on the D80v2. But it appears that Lexel is currently in violation of the license and I’m hoping he’ll resolve that soon by providing source code and answers.
For now, I’d suggest that people read Flintrock’s thread for details about how to use the light.
