STRUCT AD7606_CHAN_INFO(9)

💜 struct ad7606_chan_info(9) — channel configuration, bestie

okay so this is a page from the Kernel API Manual and it's literally just the vibe check on one struct, so let's get into it 🫶

---

✨ NAME ✨

struct ad7606_chan_info — channel configuration. that's it, that's the whole name. it's giving "i configure one channel and i do it fabulously" 💅

---

🌸 SYNOPSIS 🌸

struct ad7606_chan_info {
  #define AD760X_MAX_SCALES               16;
    const unsigned int              (*scale_avail)[2];
    unsigned int                    num_scales;
    unsigned int                    range;
    unsigned int                    reg_offset;
    unsigned int                    r_gain;
 };

yes she has a #define living inside the struct declaration, no i will not be explaining that further, i did not write it 😭 — it's AD760X_MAX_SCALES and it's 16. iconic of her.

🎀 Members 🎀

quick tour of every single field, no skips, no cuts, we're doing all of them 💖

• scale_avail — pointer to the array which stores the available scales. like a lil menu of scales, and this points at it 🍓
• num_scales — number of elements stored in the scale_avail array. how many things are on the menu. counting is important bestie ✨
• range — voltage range selection, selects which scale to apply. this is the actual choosing, the main character of the struct lowkey 👑
• reg_offset — offset for the register value, to be applied when writing the value of range to the register value. yes it's offsets on offsets, that's the bit, that's the deal 🔥
• r_gain — gain resistor value in ohms, to be set to match the external r_filter value. ohms!! real units!! she's matching her external r_filter, as one does 🦋

iykyk 💀

fr fr: keep r_gain in ohms and matched to the external r_filter value, that's literally what the member says and i'm just the messenger 🧚

⭐ that's the whole page, nothing missing, no cap. this one's from ./drivers/iio/adc, dated October 2026, and it's called struct ad7606_chan_info(9) — mwah, periodt 💜🎀
