Features:
ctr-led-brary is a small 3ds c++ library to allow homebrew developers to create and play color patterns with the 3DS LEDs. The library can do the following:

• Generate different types of color patterns, including constant, linear and sinusoidal.
• Set the pattern and loop delay and smoothing values.
• Play and Stop the generated color patterns with the Notification LED.

Planned Features:

• Add blending operations to allow a bigger range of color patterns to be made.
• Support the other LEDs (power, camera, 3D slider, wifi)

Documentation & Download:
You can find all the documentation on how to use the library and the download here: Github Page

Sure, but what exactly would you want?

 

[Deleted User]

Nice. Gonna mess around with this later.

 

[Beerus]

just have it in the misc menu so we could change notificaion led colours any time we want instead of going into a howbrew to launch mcu changer

Wow, nice work

 

[DanBro]

I was actually looking for something like this a while back, thanks and good work!

 

[Borbelli]

Ooh, this is pretty fun to mess around with. Can't wait to see where this goes!

 

[Manurocker95]

Nice! Gonna add this to Anim3DS x)

Pretty cool, maybe you can add a color wheel on the touch screen so users can pick a color to be lit up as. Kinda like how TWLoader has it where you can select what ever color you want while playing a DS game.

This is a library to make developers interact with the led in an easier way, it's up to the developer to choose adding a color wheel in their homebrew app.

Hoping it's possible to change the color of the power LED. For DS games, I want it to be green, like on the DS Phat/Lite consoles.

Not possible, that led is only Blue/Red. No idea if purple could be made tho.

I would be happy with a strobe of colors all the time on the home menu and in all games

It'd be really cool if someone built an NTR plugin for some of the Zelda games so that when your health is low and the low health beeping plays that it also flashes red from the LED, or something like that.

Afaik, @Nanquitas may be able to help with that game

just make sure it's slower, preferably in sinc with the beep, as the 3ds already rapidly flashes the notification light red when about to die

Really any game with health could be good to tie to the LED, have the LED green when you have full health, then cycle down to yellow, orange, and red as you lose it. I know such NTR LED plugins have been possible for some time now considering there was a topic on it a year or so ago with a proof of concept for Mario Kart 7 where in the Time Trial mode if you hit a ramp the LED would flash. A rather random thing to showcase the ability I suppose, but a proof of concept none the less that such things are definitely possible.
