Flashlight Firmware Repository

As useless as my bit of code was at least were making progress I will see if it can get a test rig built this weekend and have a play

Not sure if this works but I’ll try give it a go over the weekend.

Drat, it sounds like the easy method doesn’t work. :frowning:

I've measured some FET drivers PWM on my scope at around 17 KHz, but I've never seen one go up close to 19 KHz.

When I flash that, the driver behaves very strangely. I can’t even work out a pattern.

The driver is responding to the charger being powered, we just need to make it respond in the way that we want.
I tried this, but no dice

Plus, we need to have it check pin 3 continuously, not just when power is first applied.

OK I’ve flashed my latest attempt and I just get the modes in reverse order. My additional Beacon works tho which is a start :slight_smile:

I tried this just to see if it was doing something

If I power the driver with the charger attached but not powered, it comes on in mode 2.
If I power the driver with charger also powered, it comes on in mode 3.

I’d say that’s progress!

The problem is that it doesn’t change if you connect/disconnect the charger while the driver is already on, and I can no longer change modes (it stays in whatever mode it came on in)

-Just tried:
PCMSK = (1 << SWITCH_PIN) | (1 << STAR3_PIN);
But no luck-

It’s just occurred to me that I’m being really stupid. I don’t actually have pin 3 connected. I hadn’t but a resistor inline

OK I’m done for tonight I’ll have another crack at this tomorrow.

I’ve even tried adjusting MTN-Mom as it has temp sensor so any input would shut off but no luck so far.

Yes, but… what happens if you power up the light without the charger attached? It needs to distinguish between either of these two…

  • Charger isn’t attached.
  • Charger is attached but not powered.

… and this:

  • Charger is attached and powered.

Earlier it sounded like “attached and powered” gave the same result as “not attached”, which isn’t very useful.

Given a way to distinguish those different states, making it change while on isn’t terribly difficult.

but the charger will always be attached…. When i say charger, I am referring to the X6R charging circuit, not the actual charging cord

… oh. Then that definitely makes things easier. :slight_smile:

Sometimes I over-complicate things.

I’ve spend a good few hours today playing with this trying different tweaks on different firmwares.

Best I go was tweaking MTN_momentary_temp so that if the temp sensor reads 255 then mode_idx = 0 when I had the if, else the wrong way round it would just set mode to 0 when ever I tried to change mode but when they were to correct way round I just got very odd mode changes.

Hi TK,

Someone asked me to flash some micros for him with this firmware.
http://bazaar.launchpad.net/~toykeeper/flashlight-firmware/trunk/files/head:/ToyKeeper/blf-a6/cypreus2/

His boards are not the FET+1 so my question is will this firmware work with a regular FET driver?

I was thinking maybe if I disable the second channel and change the PWM values for the first?

Or is it more complicated than than?

It should work on a FET-only driver if you disable moon and replace all the 7135 modes with FET modes and recalculate the levels and recalibrate the OTC and voltage values.

I have been making some progress with this Pin3 turn off. The code here turns the light off when the usb cable is connected. :slight_smile:

It does have a bug tho. Once it’s turned the light off and you unplug the charger cable it will allow you to change modes then turn off again after .5s

EDIT: Made one last tweak and now it works!!! Code HERE

I’ve added an extra beacon mode, very long press to activate.

But hey it’s getting there. (BTW voltage monitoring is switched off atm so I know its not interfering with turning off ect…)

Sweeeet. I’m excited to try it this afternoon. When you unplug the cable, does it automatically come on, or do you need to press switch?

press switch and it comes back on. Sometimes it needs a moment to check its unplugged but i think if we just reduce the ticks it will be ok.

hmm did you try it with or without a resistor on pin3?

I flashed the one in the second link above and it isn’t reacting to the charger cord. I do have a resistor on it.
