STRUCT STM32_DFSDM_FILTER(9)

✨ struct stm32_dfsdm_filter(9) ✨

okay so bestie, welcome to the Kernel API Manual section 9, and today's main character is struct stm32_dfsdm_filter — literally the struct that's all about the stm32 FDSDM filter 💅 (yes, FDSDM, that's what the page says, we don't ask questions, we just vibe) 🦋

---

🌸 NAME 🌸

struct stm32_dfsdm_filter — the structure relative to the stm32 FDSDM filter 🎀

---

🧚 SYNOPSIS 🧚

here's the whole thing, copy it exactly, no cap:

struct stm32_dfsdm_filter {
    enum stm32_dfsdm_sinc_order ford;
    struct stm32_dfsdm_filter_osr flo[2];
    unsigned int sync_mode;
    unsigned int fast;
 };

like, that's it. four members. four little besties. adorable. 🫶

👑 Members 👑

• ford — the filter order. it's an enum stm32_dfsdm_sinc_order, which is giving "I have opinions about ordering" energy ⭐
• flo — the filter oversampling data table, and it's indexed by the fast mode flag. it's an array of 2 of struct stm32_dfsdm_filter_osr — one slot for each fast-mode vibe, iykyk 🔥
• sync_mode — the filter synchronized with filter 0. yes, filter numero zero. it's the main character and this filter is its plus-one 😭
• fast — the filter fast mode. zoom zoom, unsigned int style 💀

go read them, they're all interconnected, it's giving cinematic universe 🌈

ngl bestie, this whole thing lives under ./drivers/iio/adc — that's the address, don't lose it 🙈

and that's the page!! slay 🎀✨💜

— cute lil sign-off from the ./drivers/iio/adc girlies, dated October 2026, and the page header still says struct stm32_dfsdm_filter(9) because some things are iconic and stay iconic 👑💅
