iio_read_channel_raw(9)

💖 iio_read_channel_raw(9) 💖

okay bestie, welcome to the Kernel API Manual page for iio_read_channel_raw(9) — this is the little manual moment for reading from a given channel. ✨

---

🌸 NAME 🌸

iio_read_channel_raw — read from a given channel. 💅

---

✨ SYNOPSIS ✨

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

---

🎀 ARGUMENTS 🎀

• chan — the channel being queried. 🫶
• val — value read back. 💖

---

🦋 DESCRIPTION 🦋

Note, if standard units are required, raw reads from iio channels need the offset (default 0) and scale (default 1) to be applied as (raw + offset) * scale. That's the math, no cap — literally the whole glow-up. ✨
