iio_read_max_channel_raw(9)

🌈 iio_read_max_channel_raw(9) 🌈

okay so bestie, welcome to the Kernel API Manual page for iio_read_max_channel_raw(9). This one is short, cute, and lowkey all about asking a channel for its biggest possible raw value. ✨

---

✨ NAME ✨

iio_read_max_channel_raw — read maximum available raw value from a given channel, i.e. the maximum possible value. 💖

---

🌸 SYNOPSIS 🌸

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

---

🫶 ARGUMENTS 🫶

• chan — the channel being queried. 🦋
• val — value read back. 🎀

---

💅 DESCRIPTION 💅

okay so here's the note, and it's important, bestie:

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 formula. The offset default is 0, the scale default is 1, and the whole vibe is (raw + offset) * scale. no cap. ✨
