The driver can be configured in user settings not to use the main LED for battery, Temp and LVP blinks
The only thing on 2S light is that the pin 7 of the MCU either has LVP detection input or indicator output
If you got the indicator output is still possible to use another LED color in side switch to show if the driver gets Battery voltage simply connecting this LED with a resistor to the drivers supply voltage
Yeah, that’s right. On 2S models, you have to choose between indicator light or LVP. I always choose LVP because that is more important.
Both my Narsil lights are 2S so I have no indicator function. It’s no big deal, though. I still have a lighted side switch that tells me if power is connected or shut off. That’s all I need.
2S are also the only ones I see as potentially truly calibration free, assuming the LDO has good specs. invered, or "Internal" read, divider-less 1S still uses the 1.1V internal reference (so does the normal method not referred to as "internal"), but on 2S you can reference the LDO. The inerntal 1.1V reference has a +/-10% tolerance, so I don't see anyway around needing calibration on that in principle, although I've had good luck with the couple of inverted read builds that I've tried. I doubt narsil is referencing to the LDO either, but I'm not sure. I doubt it because generally you'd try not to use different methods for everything. OTSM 2S requires referencing to the LDO though, as there's just no other way for OTSM without using another pin. It just happens to get the benefit of a hopefully more stable reference.
Of course for FET+1, not triple, there's an extra pin available for indicator. On HD it's just a matter of defining that pin as the indicator pin and setting the use indicator option and you're in business. But HD doesn't really work right on e-switch yet.
Of course one more way is to just make a dumb hardware-controlled indicator. Just wire it to the switch. it will be on normally, and off when the switch is pressed. No programming obviously.
doing the last drivers of this batch programming, testing and calibrating today
also upgraded my testing gear a bit
XHP50 High CRI now for 2S
Heatsink upgraded now has fan running when I turn the switch on
the tip with ground is my switch emulation
Swapped the MF01 to NarsilM. Great driver. Works great! BAM!! Turbo. Smooth ramp. Feels like the Q8. Batt check, lockout…perfect. Did not use the sw indicator. Keep up the great work. Now re-charging…lol. Power levels are super!!! CW version. Saved the NW.
