ds2482_set_channel(9)

💅 ds2482_set_channel — kernel API manual, but make it make sense 🎀

okay so bestie, this page is ds2482_set_channel(9) from the Kernel API Manual, and it's literally the littlest function with the biggest "do not mess this up" energy. it picks which w1 channel you're talking to, and there's exactly one rule you cannot fumble: the 1-wire interface must be idle before you call this. not "kinda idle", not "idle-ish", idle. periodt. 💖
