The GT driver has one pin to control the constant current circuit’s current level, and one pin to turn it on and off. For the top 90% of its power range, it’s set to “on” (255/255) while varying the power level. For the bottom 10, it’s PWM’d at 10 power.

Thank you TK. Very good info. Was looking at the circuit for the GT driver just a bit ago and saw both pins feeding the buck converter. One via a voltage divider with a cap and the other directly connected. Might be able to use the hex file for a FET only driver for the time being. Having trouble building a solution on my own and want to move on with the build.
I have recently translated Sofirn's manual for the new SP36 into German language. This flashlight comes with NarsilM 1.2. Since more and more native speakers ask for a German version I thought it might be good idea to share the translation of NarsilM here and on TLF (German flashlight forum). Sofirn agreed upon this plan, too. Before actually releasing it to the community - are there any constraints like copyright, licensing agreements etc. I need to consider. What would be the best format to share it? I could provide it directly into this or a new thread or I could also provide a link to a pdf-file.
Let me know what you think. :-)
Cheers,
Thomas
With NarsilM on the Lumintop GT Micro, is there a way to leave the e-switch locator led on while the main LED is on? It can be hard to find in the dark.
Sorry, no unfortunately. I really wanted to get it implemented as a feature though. My GT Micro's switch LED is pretty dull though - not sure how well it would show up with the main LED on.
What is the latest version of Narsil?
Where can it be downloaded?
Still V1.3 - I've still be using it often.
I just posted my latest v1.3 source code here: https://drive.google.com/open?id=1i42GnkD6LBvxEK3_fiZVdrZsFkNuLZsU
Let me know if you can access it ok. If you are used to building NarsilM, I got a ton of Setups.h files that Iv'e used. You have to carefully go thru things and make sure you pick a proper setup config to use, then tweak as you like. Please check the Rev History.txt file carefully for the most recent changes.
Thanks Tom, got a message about a network error but it downloaded fine.
Thanks, Tom!
It’s pretty stellar UI.
Thanks. I updated the copy in my repository to this version.
Was just reading random parts of the message thread and came across this. Is there some already some Olight S-Mini clone with e-switch firmware?
There is Olight S1 clone with e-switch firmware, but not S-Mini.
Hey hey people
Just got my Astrolux FT03 today - the end of the ramping is not the maximum brightness - but I don’t want to have a turbo-mode, I want that light to ramp up to it’s full power like I can with Anduril.
Since this is my first NarsilM driver - is it possible, too?
didn’t find it in the manual though
Thanks!
No you can’t change ramping floor and ceiling in Narsil
OK thanks.
I think older versions of Narsil had the ramp ceiling equal to max output. My BLF Q8 seems to work like that. But the FT03 uses a more recent version of Narsil. I guess they changed it for some reason.
NarsilM had the ramp ceiling separated from the turbo level during development of the BLF GT. The GT works really well at 2.0A, but not at the full power of 2.5A. It can’t keep the output flat for very long at full power. So the ceiling was set to 2.0A, with an extra 2.5A turbo level.
This is configured at compile time though… it’s not a user-configurable option.
Yes - TK is right. I really don't like the the ramps that fall short of full max... 
I just configured a NarsilM v1.3 tonight for the SP36, for Barry, and made sure it has the full ramping to max/turbo 
.
Possible the Lexel/TA/Astrolux connection configured NarslM that way -- just checked, I NEVER used that feature for any of my own stuff, but added it in for the GT.
Not to blame anyone, but that's probably how Astrolux wanted it -- could have even been me that configured it for them - I forget a lot of things...
I don’t think you forgot it. The product listing says “Firmware: Tom E’s open-source GPL NarsilM v1.3 adapted by Texas_Ace”.
However, I don’t see a link to the code there, and don’t see a FT03 build target in the repository or in any of the scattered copies of NarsilM derivatives I’ve gathered over time. I don’t see it in TA’s Avenger driver thread either. Maybe there’s a link which comes with the light itself?
Or maybe it’s another license issue to clean up. Sigh. Hopefully I just looked past the link somewhere.
Any idea where the FT03 source code is?
