STRUCT ST_LSM6DSX_EXT_DEV_SETTINGS(9)

💖 struct st_lsm6dsx_ext_dev_settings(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for struct st_lsm6dsx_ext_dev_settings — yes the header abbreviates it as struct st_ls...dev_settings(9) but we're gonna say the whole thing, periodt ✨

---

🌸 NAME 🌸

struct st_lsm6dsx_ext_dev_settings — the i2c controller slave settings, literally the little config bundle that tells the driver how to talk to an external sensor hanging off the hub. no cap 🫶

---

🎀 SYNOPSIS 🎀

struct st_lsm6dsx_ext_dev_settings {
    u8 i2c_addr[2];
    struct {
      u8 addr;
      u8 val;
    } wai;
    enum st_lsm6dsx_ext_sensor_id id;
    struct st_lsm6dsx_odr_table_entry odr_table;
    struct st_lsm6dsx_fs_table_entry fs_table;
    struct st_lsm6dsx_reg temp_comp;
    struct {
      struct st_lsm6dsx_reg reg;
      u8 off_val;
      u8 on_val;
    } pwr_table;
    struct st_lsm6dsx_reg off_canc;
    struct st_lsm6dsx_reg bdu;
    struct {
      u8 addr;
      u8 len;
    } out;
 };

copy that exactly, don't be out here renaming fields, i'm watching 👀

🦋 Members 🦋

• i2c_addr — the I2c slave address list. that's it, that's the vibe 💅
• wai — Wai address info. who is this sensor? this struct is how we find out 🙈
• id — the external sensor id, so we know which one we're dealing with.
• odr_table — Output data rate of the sensor [Hz]. yes, hertz, we measure in hertz here ⭐
• fs_table — the Configured sensor sensitivity table depending on full scale. scale goes brrr 🌈
• temp_comp — Temperature compensation register info (addr + mask). keep it chill 🧚
• pwr_table — Power on register info (addr + mask). main character energy fr fr 🔥
• off_canc — Offset cancellation register info (addr + mask).
• bdu — Block data update register info (addr + mask).
• out — Output register info. the moment of truth 🍓

ngl all those "(addr + mask)" ones are literally the same shape — register address plus its mask. iconic consistency, we love to see it 💜
