Details

After reading the irc log shortly after the flashlight plugin was committed i noticed that some want the ability back to finetune the colour of the display. This time i've added a fixed point version of the hsv_to_lcd version (thanks to amiconn) and added some more predefined colours. You can "skip" forwards or backwards to the nearest predefined colour (however, it's probably not the nicest way of doing it i guess).

I've also implemented another request to switch the backlight on and off (even for non colour targets) and it now uses the remote backlight too.


Controls:
Targets with a 4 button cross:
Up/Down: fine tune
Left/Right: jump to next predefined colours (including white)
Select: switch backlight on and off

Targets with scroll wheel:
Scroll left/right: fine tune
Left/right or fwd/rew: jump to next predefined colours (including white)
Select: switch backlight on and off

I've tried to guess the most intuitive button layout on all targets and even use the remote buttons. However i only own a small number of targets so if you think it can be done better let me know. :-)

Tested on iPod Video, Mini (sim), H300 (sim) and m:robe 100.
This task depends upon

One feature that's specific for the Sansa e200 series would be to also turn on the blue wheel light, since i always have it off (i presume other users also). So with the brightness set to max and the wheel light on, it really becomes a flashlight.

* Added missing Keypad (Ondio)
* Added support for buttonlights and (where available) setting the buttonlight to max brightness (gigabeat f for example)

If you can explain me the need of being able to turn the backlight of, I'll by chance like it.

Don't know. It was a feature request in IRC and i thought i can't hurt.

* Make sure the plugin quits if USB is connected.

@kugel: the need is very easily explained. The plugin should work like a real flashlight which you usually can turn on and off.

@DerPapst: shoudn't the plugin return a special value (and not just PLUGIN_OK) if USB has been detected?
Comment by Thomas Martitz (kugel.) - Friday, 25 April 2008, 22:03 GMT+2
That's why you can exit the plugin with like every button (except the one to change the color of course).

BTW: Does a real flashlight offer some fancy color spectacle? I don't think so.

> That's why you can exit the plugin with like every button

...and then having the problem to start it again (with another button). A real flashlight does not usually have fancy colors but this not related to the ability to turn it on/off.
Comment by Thomas Martitz (kugel.) - Friday, 25 April 2008, 23:45 GMT+2
Let me get this right. Without this the ability to turn the backlight off, you exit the plugin with select and (re-)start it with select (select button in most cases). With the ability you do turn the backlight on and off.

I don't see any difference. Isn't exiting the plugin the same as turning the flashlight off?
Comment by Thomas Martitz (kugel.) - Friday, 25 April 2008, 23:46 GMT+2
Ok, the only difference is, that in one case the backlight is off, and in the other the menu shows up. Looks like a big deal.

I had some discussions with other users about flashlight before i implemented this whole stuff. Someone preferred one button to quit the plugin instead of any undefined one since one might press it accidentally.
Also i don't quiet get what the problem is with turning the backlight on and off in flashlight. It's not like that it hurts somebody. If you don't like it, don't use it and quit the plugin instead of using this feature. Also one could argue that if you quit the plugin the backlight (and button light) isn't instantly off. But whatever. I didn't expect so much emotions because of such a small plugin :-)

* return PLUGIN_USB_CONNECTED if usb is connected.

@DerPapst: quality control passed ... almost :-) Just one question. Is it ok to call "rb->default_event_handler(button)" twice? (It gets called twice in case of USB.)
Comment by Alexander Levin (fml2) - Saturday, 26 April 2008, 08:39 GMT+2
Attached is a patch improving that (hoefully).
Comment by Alexander Levin (fml2) - Saturday, 26 April 2008, 08:40 GMT+2
*hopefully :-)
Comment by Alexander Papst (DerPapst) - Sunday, 27 April 2008, 19:13 GMT+2
I think it is OK to call the default_event_handler twice. It at least worked OK in my tests. I think either version is fine :-)

Oops... :-)

This patch only implements the request of Jeton (button light) since i think this is still a good idea.
