temperature_from_RAM(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

Okay so bestie, welcome to the Kernel API Manual, and today's main character is temperature_from_RAM(9) — she takes the read info and converts it to temperature. That's the whole job description, and she does it slayfully. 💖

✨ SYNOPSIS

int temperature_from_RAM (struct w1_slave *sl , u8 rom[9] );

Like, look at her. Two args, returns an int, no drama. 🌸

🎀 ARGUMENTS

  • sl — the device that sent the RAM data. She's the one who brought the receipts, so we know where the data came from.
  • rom — the read value on the slave device RAM, chillin' there as a u8 rom[9] array. Nine bytes of pure potential. 🦋

🧚 DESCRIPTION

Okay so here's the vibe: this function is device dependent, and what she does is bind the correct computation method. Different device families, different math — she's basically the group chat admin who knows exactly which friend to tag for which question. No cap, that's the whole flex. 💅

🔥 RETURN

The temperature comes back in 1/1000degC (yes, thousandths of a degree, she's precise like that ✨), and 0 on error. So if you get a zero, don't celebrate — check yourself before you wreck yourself. 😭

🌈 SEE ALSO

Kernel file ./drivers/w1/slaves/w1_therm.c struct — and honestly the whole friend group is here, so let's go:

Fr fr, go read them if you want the full lore. The whole squad ate and left no crumbs. 👑

That's the page, babe — sourced from ./drivers/w1/slaves, dated October 2026, and it's temperature_from_RAM(9) all day. 🫶💜 Byeee! 🎀
