sht15_update_status(9)

✨ sht15_update_status ✨

okay so bestie, welcome to the sht15_update_status page 💅 this is a little gem straight out of the Kernel API Manual, and honestly? it's giving "small function, big responsibilities." periodt.

---

🌸 SYNOPSIS 🌸

int sht15_update_status (struct sht15_data *data );

like, that's the whole signature. one argument, one int coming back at you 🫶

---

🎀 ARGUMENTS 🎀

• data — the device-instance-specific data 🦋 that's your lil' bundle of joy holding everything this particular SHT15 device needs to know about itself. never lose it, bestie.

---

💖 DESCRIPTION 💖

so what does it actually do? it grabs an updated status register from the device — but only if the one you've got is too old 😭. no stale status registers in this house.

and if you want the receipts, the whole thing is laid out in figure 15 and table 5 of the datasheet 📖 — that's literally the source of truth, go read it, iykyk.

💀 reminder bestie: this is kernel API territory, so treat every one of those functions with main-character respect — this is not the place to be guessing at behaviour.
