💫 ow — the Dallas Semiconductor 1-Wire bus, bestie 💫

okay so like. the manual name is ow and it lives in section 4 of the Kernel Interfaces Manual, and honestly? iconic. let's get into it 🫶

✨ SYNOPSIS ✨

device ow

that's it. that's the whole vibe. one line. ate. 💅

🌸 DESCRIPTION 🌸

so the ow module is the one that implements the Dallas Semiconductor 1-Wire bus, and if you're like "what does that even mean" — no worries, we got you 💖

here's the tea: ow doesn't do the low-level signaling stuff itself. nope! it attaches to the owc(4) driver, and that driver is the one implementing the low-level signaling of the 1-Wire bus. so they're a lil duo — ow handles the bus, owc(4) handles the actual wire-level chatter. main character + supporting character energy, fr fr 👑
