Homebrew 3DS Devkitpro infrared - minimal functioning program

[Ventuaer]

Hey, I've been trying to find anything about the IR transciever on the 3DS, but looks like I am unable to find absolutely anything. The devkitpro library looks like it does not have any code.
I have a feeling that my only remaining hope is to analyze some assembler code from games that use it :/

I wonder if the 3DS has some functionality (assembler instructions) built in for the ease of IR, but my hopes are thin.

How can I proceed, has anyone met this sort of problem?

I remember seeing in the assembler code of Pokémon ORAS routines related to IR/Wi-Fi and other features used for Mystery Gifts. I can take a look and see what I can find.

If you can take a look, that would be amazing. I will probably have to dive into it as well, but I haven't yet tried reversing 3DS code, I only have knowledge with the x86-64 assembler.

What do you actually want to do with the IR btw ? // Because the libctru can already handle IR, I just checked: you have iruInit,
iruSendData, etc. x)

Oh! Did not know that! I was scouting with google yesterday, no mention of iruInit, but seems that I was wrong! I was only looking around devkitpro, not just the libctru.
I want to try to emulate pokewalker on the 3DS
There exist hardware versions, but I feel like the 3DS is theoretically capable, as it has IR transmitter and a pedometer, though I am not sure if I can use daily steps in the app or that information is not available through games. Will have to figure that out either way.

If you can send me the docs I would be very happy, because as of right now i can't find it it seems

Ah ok, funny project x'D

Amazing, will get to it in the evening, cheers! Amazing, will get to it in the evening, cheers!
