STRUCT ST_SENSOR_DATA_READY_IRQ(9)

🌸 struct st_sensor_data_ready_irq(9) 🌸

okay so bestie, this one comes from the Kernel API Manual and it's literally the blueprint for the ST sensor device data-ready interrupt. Think of it as the group chat notification that says "fresh sensor data just dropped" — but in struct form. 💅✨

✨ NAME ✨

struct st_sensor_data_ready_irq — ST sensor device data-ready interrupt. That's the whole name, no cap. 🫶

🎀 SYNOPSIS 🎀

bestie, here's the struct in all its exact glory — don't let the nested structs intimidate you, they're just little babies doing their jobs:

struct st_sensor_data_ready_irq {
    struct st_sensor_int_drdy int1;
    struct st_sensor_int_drdy int2;
    u8 addr_ihl;
    u8 mask_ihl;
    struct {
      u8 addr;
      u8 mask;
    } stat_drdy;
    struct {
      u8 en_addr;
      u8 en_mask;
    } ig1;
 };

👑 Members 👑

• int1 — data-ready configuration register for the INT1 pin. It's giving INT1 main character energy. 🎀
• int2 — data-ready configuration register for the INT2 pin. INT2 said "me too, bestie." 💖
• addr_ihl — address to enable/disable active low on the INT lines. Lowkey the address that flips the active-low setting. 🌈
• mask_ihl — mask to enable/disable active low on the INT lines. The matching mask for that active-low toggle. ✨
• stat_drdy — status register of DRDY (data ready) interrupt. In the struct it's this little combo: struct { u8 addr; u8 mask; }. 🍓
• ig1 — represents the Interrupt Generator 1 of sensors. It's the struct { u8 en_addr; u8 en_mask; } part, just doing its generator thing. 👑
