yes, sorry. I didn't remember correctly when i wrote the post.

Just some more details:

led current in flash and torch are checked against an intensity table to validate them:
static struct brightness_entry flash_brightness_map[] = {
{0x0, 38},
{0x1, 75},
{0x2, 113},
{0x3, 150},
{0x4, 188},
{0x5, 225},
{0x6, 263},
{0x7, 300},
{0x8, 338},
{0x9, 375},
{0xA, 413},
{0xB, 450},
{0xC, 488},
{0xD, 525},
{0xE, 563},
{0xF, 600}
};

static struct brightness_entry torch_brightness_map[] = {
{0x0, 18},
{0x1, 37},
{0x2, 56},
{0x3, 75},
{0x4, 93},
{0x5, 112},
{0x6, 131},
{0x7, 150},
};

where the second number is intensity. So it should not be the risk to damage led (at least in torch mode). Duration is max 1024 (milliseconds?) for flash mode.

I've just submitted an update to LED Torch.

v0.2.7 - October 12, 2011
- Re-added SysToolsMgr package dependency flag (forgot to include it in 0.2.6)

v0.2.6 - October 11, 2011
- Special compatibility improvements for Pre3's led flash brightness scale, thanks to mpx

Supports the brightness range from 18mA to 150mA

Won't be on the feed for a few hours until the feed gets refreshed and notices the updated app. So in the meantime, feel free to install the .ipk manually from http://dl.dropbox.com/u/2774158/ca.c..._0.2.7_all.ipk


Make sure you have the new just-released v1.0.5 SysToolsMgr is you're using it on a Pre3.

Huge thanks. I just donated a very small token of appreciation. Much more is owed to you and the rest of the Homebrew/Internaz folks.

Torch, Torch, Hurray!

Just to confirm - works like charm - both application as well as alternative methods to turn it on (I use one of the system menu mods).

thanks for the new version Jason, it was the biggest thing I was missing on my Pre3.

a little bug though with the app: it won't respect the brightness setting if I set it with the led off - I have to turn it on then set the brightness. this is on an AT&T Pre3 w/2.2.3 if that makes any difference.

also the first time I tried it I couldn't get it to turn off without closing the app then re-opening it, but that hasn't recurred since so it was probably a one-time glitch.

oddly, I'm not able to reproduce the bugs you mention. Can you confirm you are on v0.2.6 of LED Torch and v1.0.5 of SysToolsMgr?

[mpx]

I confirm the bug.

But it's not a bug, it's a feature. :-P I think it is caused by the fact that the kernel ignore all settings made until the led is turned on.
You can see the reject on /var/log/messages

definitely on v0.2.6 & v1.0.5. didn't have either package installed before, as I knew they didn't work.

perhaps after you make the call to turn on the LED, you could set the brightness again?

Thanks Jason.
You are great!!!

Any chance to work in the Pixi Plus?

[nattysinister]

Please can someone tell about it's compatibility with pixi.

as has been noted many time on previous pages, and other forum threads, the pixi uses an unknown proprietary LED flash controller format and thus doesn't work in LED Torch or any other flashlight apps currently

Jason - do you know if anyone has ever asked HP to release the info on this controller?

Not sure. I know the most that's been offered up so far was the camera c headers.
