✨ iio_write_channel_raw(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this is the page for iio_write_channel_raw(9), and honestly? it's a whole little icon. let's get into it 🦋

---

🌸 NAME 🌸

iio_write_channel_raw — write to a given channel. that's it, that's the vibe 🎀

---

⭐ SYNOPSIS ⭐

int iio_write_channel_raw (struct iio_channel *chan , int val );

---

💖 ARGUMENTS 💖

• chan — the channel being queried 👀 like, this is the one you're talking to.
• val — value being written ✍️ the actual number going in.

---

🦋 DESCRIPTION 🦋

okay so this is the part you actually need to read, bestie, don't skip it 🙈

note that for raw writes to iio channels — if the value you're providing is in standard units — you gotta remove the effect of the scale and offset first. the way that works is:

(value / scale) - offset

that's the formula, periodt. no cap. 💀
