STRUCT STM32_DFSDM_FILTER_OSR(9)

✨ NAME ✨

struct stm32_dfsdm_filter_osr — okay so this is the DFSDM filter settings struct that's linked to oversampling 💖 it's from the Kernel API Manual, and yes bestie we're reading kernel headers for fun now, that's the vibe 🎀

🌸 SYNOPSIS 🌸

struct stm32_dfsdm_filter_osr {
    unsigned int iosr;
    unsigned int fosr;
    unsigned int rshift;
    unsigned int lshift;
    u64 res;
    u32 bits;
    s32 max;
 };

seven members, one struct, zero notes of caution — she's a plain lil data holder and we love that for her 🫶

💅 Members

• iosr — the integrator oversampling, literally the integrator's oversampling value 👑
• fosr — the filter oversampling, same energy but for the filter ✨
• rshift — output sample right shift — and this one's the hardware shift, no cap 💀
• lshift — output sample left shift, and this one is the software shift — yes they're two different things, iykyk 🦋
• res — output sample resolution 🌸
• bits — output sample resolution in bits, the same resolution but counted in bits, she's giving metric-and-imperial 😭
• max — output sample maximum positive value, the ceiling, the limit, the main character's upper bound 🔥

🦋 SEE ALSO 🦋

• Kernel file ./drivers/iio/adc/stm32-dfsdm.h — the actual home of this struct 🏠
• struct stm32_dfsdm_filter(9)
• struct stm32_dfsdm_channel(9)
• struct stm32_dfsdm(9)

go read the whole little family, they're all in the same header and they slay together 💜

mwah 💋 that's the whole page — brought to you by ./drivers/iio/adc, Kernel API Manual, dated October 2026, aka struct stm3...m_filter_osr(9) if you're squinting at a narrow terminal 💅✨
