Homebrew [Release] 3DS RGB LED test program

[Sono]

so its safe¿?

Yes, I'm now speaking with yellows8, and I just tested his code, and it didn't brick my old3DS, so I guess it was just extremely bad luck

Edit: yes, you can power off and it'll even have a cool effect when you turn it back on

can u do something like to do a special notification with a custom-choice led¿?

Well, this is an RGB LED, so it can display 2^24 possible colors, so you can program it as you want! You have 32 pattern slots for each color, and you can set smoothing and speed, so I guess it's good enough

This wouldn't risk an I2C firmware wipeout? MCU brick is unrecoverable even with Hardmod.

 

[leerz]

there should be sound "tugs tugs tugs tugs!" amazing work

Any way to make it not die when you close and open your ds?

In 3DS mode? 'cause it doesn't die in DS/DSi mode.

It stops when you shut it and open (put it in sleep mode I guess)

Probably because the Home Menu clears the pattern when opening the lid, just like when you have a notification.

It doesnt for me; shutting and opening my o3DS xL doesnt clear it
EDIT: The fading in white is really funny; it paused when I put in my PIN

In the ds mode it still shines after standby and when u open the lid. I haven't tested it in agb mode yet.

Just compiled it to 3dsx. launched via Homebrew Launcher. this makes HBL Very cool! on the HBL will automatically close the program itself and blinking background! and keep blinking after you close the HBL.

In x86, there's a [kernel-level] cli instruction that'll disable interrupts. If there's an ARM equivalent, you could possibly use it to protect against bricks.

Ye, use any makefile, and just put the sooscode in the soos folder

I have mentioned countless times, this is safe!

It takes a little bit of time to enter sleep mode I said "exiting sleep mode" for a good reason

iirc you are not allowed to disable interrupts, but it doesn't matter anyways because how the MCU communication works.

ARM11:
homebrew -> ptm:sysm -> mcu::RTC or mcu::HWC -> mcu sysmodule queue -> I2C -> MCU
ARM9:
I2C <--> MCU

as you can see, disabling interrupts would have no effect at all.

I use this function to get an accurate rainbow pattern (it's made in lua, so you'll have to translate it to C)

red = math.modf(math.sin(0.00202683548*Timer.getTime(rnbw_timer) + 0) * 127 + 128)
green = math.modf(math.sin(0.00202683548*Timer.getTime(rnbw_timer) + 2.0943951) * 127 + 128)
blue = math.modf(math.sin(0.00202683548*Timer.getTime(rnbw_timer) + 4.1887902) * 127 + 128)

Note that rnbw_timer is a variable that goes from 0 to 3100.

Read the channel description sooscode, and you'll notice something...
