Flashlight User Interface Cheatsheets

Came across couple of firmware name at aliexpress, i wonder where i can learn about firmwares. I found it right here. Thanks Crx, great thread. :+1:

While this thread is on top again thought I’d just say thanks CRX for taking the time to gather all the BLF cheatsheets in one place, very helpful thread. :wink:

Thanks guys :+1:

Keep coming back just to check what exactly i f&@“ up… LOL
Many thx CRX for this thread and everyone who’s sending updates

A little OT, im sorry, but what is the Firmware for driver with 2 channel output, 1 for main led, and 1 for aux led, clicky switch, thank you very much

Thank you CRX. I use your cheat sheets almost daily. Saves a lot of frustration.

There could be many. What light is it or what driver specifically?

it’s convoy s2+ with biscotti driver, triple leds, and i’m planning but an AUX led under TIR lens

since the driver is 1 channel , i can hook a wire from MCU to aux led

I’m not really understanding you. Are you saying you have Biscotti now, but want to flash a different UI, but you don’t know the name of the new UI?

I’m not familiar either. You might try asking Toykeeper since she wrote Biscotti.

Your sure such a UI exists?

Yup, my s2+ has Biscotti driver, now i want to mod it with AUX leds, but i am not sure what firmware support aux led?, anduril supports AUX led, but it’s only for e-switch

You already know how to get power to the driver when the rear switch is off?

Well, my plan is not turning it off at all.

You want to have the main LED on all the time? Battery will run down fast. I’m not understanding your logic.

you misunderstood me, i’m sorry since English is not my native language, so it’s maybe hard for you to understand me

i have stock convoy s2+, it has 8*amc7135 driver, now i want to have an AUX leds under the TIR len( the tir len is install by me), the problem is the stock driver doesn’t support AUX leds, so right now i’m looking for firmware that support AUX leds. Something like Anduril Firmware, but changing mode through tail switch, not e-switch

the driver will be powered all the time, like E-switch driver. MCU will be in low power state so it won’t consume much energy

So useful, thank you.

Rear clicky drivers like the one in the S2 are designed to be controlled by removing power from the driver since there is no other input. The rear switch connects the battery to the driver.

The way the driver knows if the power has been removed for a second or a day is through an OTF or Off Time Capacitor. This keeps the driver MCU powered up very briefly (a few seconds). This allows it to measure the amount of time it was off.

Since the usual point of Aux Leds is to be On when the main Leds are Off, you would need to keep the rear switch in the On position while the main Leds are somehow turned Off.

This fundamental problem is why you never see Aux Leds on rear clicky lights. I certainly have never seen it.

This is why I asked you if you somehow found a way around this basic problem.

The only solution I can think of is a special UI that includes an “Main Led Off” as part of the brightness cycle. So you would blink the rear switch quickly to cycle through the modes such as: low, med, high, off/standby, low, med, etc…

I don’t know if such a UI exists. I would suggest you ask Toykeeper or Tom E if they have ever heard of such a thing. Also, would you even want a UI like this?

Hey, this is a great guide!

I have a Surefire 6P running a Dr. Jones H17F behind an XP-L2 on a Keeppower 16650 that’s one of my frontline lights. I’m also testing my newest concoction, a 17mm FET driver zener-modded running Guppydrv rev2 powering an XHP50 on two 17500’s in a Surefire M3. I’ve already referred to this page a dozen times. Thanks for putting this up.

Anyone know how to reset a d4v2?

I read somewhere that this will delete muggle mode and is what I would like to accomplish, I have some harbor freight flashlights to lend to muggles during camping trips, etc

I don’t have that light, but you can try disconnecting the tailcap (battery power), hold down the button and then retighten the tail cap. If you keep that button held down more than 3 seconds that should do a factory reset.
