Battery Level Access

kalus · November 16, 2006, 10:37:43 AM

Is there any function in any currently available library that returns how much battery power the DS has?

Nope. There's no such thing.

But MAYBE you can check the green/red status over a period of time and see how much the ratio is.
Simplified: green, green, red = 66%

not quite sure if you just said this lick =\

but i remember reading on nintendos site that red= around 1 third of batt power left

Red is thirty percent, im sure

I've always wanted to do that. Even the PSP has a battery indicator that shows the amount of battery, and some emulators have a percentage of the battery as well. Is it possible to write some homebrew program to check the battery level? Or better yet, maybe the next SC firmware can have this built in?

P.S. Where is this indicator your talking about. Where is this green, green, red thingy. Can someone post a pic of what we should be loooking at?

i thought maybe you means green was 66% of the charge, leaving a third red

also, what is quite cool is if ur batters is at JUST the right level, when ur playing a game with music, the light will flashh red-green-red-greend along with the music

No I mean like for 30 frames you keep track of the green-or-red-bit (it's either 0 or 1) and you check how the ratio is.

If 15 in the 30 tracked frames were 0, and the other 15 were 1, then your battery level is roughly at 50%.

- This is great experimenting material! -

Well if you go into the boot menu, at the top, there is a icon that says how much battery you have left. So battery access is PossIBLE!!

the ds knows when the light goes red,thats for sure, but i dunno about how it works internally/ in the hardware, sounds like an interesting idea though
