STRUCT ST_SENSOR_BDU(9)

💅 struct st_sensor_bdu(9) — the Kernel API Manual, bestie edition 🎀

okay so you're in the kernel API manual and you found struct st_sensor_bdu — that's the ST sensor device block data update situation, and honestly? it's tiny but it matters. let's get into it ✨

---

🌸 NAME 🌸

struct st_sensor_bdu — ST sensor device block data update. that's the whole vibe. it's a struct, it's about block data update on ST sensor devices, and it's here to help 🫶

---

✨ SYNOPSIS ✨

struct st_sensor_bdu {
    u8 addr;
    u8 mask;
 };

two little u8 fields. that's it. iconic minimalism, no notes 💅

---

🦋 Members 🦋

• addr — the address of the register. like, which register we're talking to. that's the one 📍
• mask — the mask you use to write the block data update flag. yes queen, mask it up 🎭

---

👑 SEE ALSO 👑

• the kernel file ./include/linux/iio/common/st_sensors.h — go read it, it's giving main character energy 🌈
• struct st_sensor_das(9)
• struct st_sensor_int_drdy(9)
• struct st_sensor_data_ready_irq(9)
• struct st_sensor_settings(9)
• struct st_sensor_data(9)

all the sibling structs, the whole friend group, fr fr 💖

---

lowkey reminder: addr is the register address and mask is the mask for writing the block data update flag. that's the entire fact set, don't let anyone tell you otherwise ✨

and that's the page bestie!! 🦋 sign-off time: this one lives over in ./include/linux/iio/common, it's dated October 2026, and it's filed under struct st_sensor_bdu(9). slay, go forth and update your block data 💜🎀
