Homebrew [Release] 3DS RGB LED test program

[Deleted User]

Somthing else you can do with this is you can use mcu dimmer while mcu bricker is on too if you want the blue battery/wifi light off with the rainbow led on.

So now that this is apart of TWLoader does this actually have a chance of bricking? It's really fucking neat though.

No chance of a brick unless you're making a program and implementing it. If it works it works, no bricks.

as I said a few times, it's safe if you're on 8.1 or above, but it's risky below 7.0

OMG this is awesome!!! Play rave music in 3DS sound or just play Mario kart 7 with this running for no reason XD. Pretty freaking sweet. I wonder if people with 3DS's who don't have this would wonder how the crap are you getting a rainbow notification. XD just simply fantastic.

can you make an homebrew to burn that light to death?
that 3d light is annoying as hell, specially when not using the 3d

Make it opposite day for the 3DS system, 3D light on when it's not needed, 3D light off when 3D is available.

Since it's a LED, I doubt it'll die any time soon :/ I could flicker it, but that would kill the MCU faster than the LED itself.
Also, it's not that easy to control the 3D light independendly, so it would not die either any time soon.

Edit: I thought you were talking about the RGB led in the first sentence... You can't flicker the 3D LED like you can the RGB LED.

Wait... You can kill the MCU by flickering a led light fast?

ALSO I need to report a bug to you all, I just turned my system off while this was running, it looked creepy as the system shutdown but when I turned it back on the light was lit orange for several seconds in a creepy glow then went pitch black. It went back to normal after that... Think you could please take a look at that could you.

No, I believe he means a flickering red light decreases the life of the MCU faster than that of the LED. Not necessarily how fast the red light flickers.

That's not a bug, that happens normally. If your 3DS turns off when the RGB LED is on for anything (including notifications), it will do the same thing.
Try getting an orange light for a friend becoming online, and then have your 3DS turn off while that light is still on. It's happened to me twice on accident (this was before I had any hax) and I thought it was really cool.

Ok 1 question, just so I can fully understand, what exactly is a MCU

(MCU)Microcontroller Unit, it's essentially the brain, it monitors the HOME button, WiFi switch, 3D slider, volume control slider. Controls LEDs, various power supplies via an I²C connection to the PMIC.

That's why it's an unrecoverable brick.

Oh derp, thank you for telling me.

It also controls the screens, right? Or am I mistaken?

I think so. A while ago, there was a rumor that an MCU brick could be recoverable via a a9lh payload that does not use screen-init.

Two I²C buses are attached to the MCU. For one, the SoC is the master; for the other, the MCU is the master.

Devices attached to MCU master I²C bus:

• MCU (master)
• Fuel Gauge
• Accelerometer (slave address 0x18)
• PMIC
• maybe more?

Devices attached to the SoC master I²C bus:

• SoC (master)
• MCU
• LCD
• Camera
• QTM (New3DS-only)

You are correct.

Does the current popular distro of A9LH v2 do screen init?

Not relevant to this thread, but name arm9loaderhax.bin to arm9loaderhax_si.bin

I ask because I like to know I'm playing it safe, and should I want to test out one of these LED programs, I want to know if I could boot my A9LH in non screen init mode and unbrick the MCU. By having to explicitly add "_si" to the name, I take it that it isn't initialized by default so I'm safe to try?

Even if you did get an MCU brick there's no payload to unbrick.

Welp... have you seen the filename? The logo/banner? The application name?

Spoiler

yellows8 permanently bricked his 3DS this way [emoji14]
It's in the EoF, because almost no random noobs browse the EoF, so they can't accidently brick [emoji14] Even tho' this app has auto-exit, I wouldn't like mindless people complaining if they permanently break their 3DS motherboard

Why on earth would this app even exist in the titledb if all it does is brick??

It doesn't actually brick lol. It was assumed that it can brick your 3ds. @MarcusD did research and testing and found it as impossible to brick.

So you promise nothing will go even 0.01% wrong?
