✨ ds2482_send_cmd_data ✨

okay so bestie, welcome to the ds2482_send_cmd_data page from the Kernel API Manual 💅 this one is short and sweet and honestly kind of iconic — it's the little helper that sends a command plus a parameter byte out to your DS2482 chip. no cap, tiny function, big main character energy 🎀

---

🌸 SYNOPSIS 🌸

int ds2482_send_cmd_data (struct ds2482_data *pdev , u8 cmd , u8 byte );

like, literally that's the whole vibe. three args, one int back. slay 🫶

---

🦋 ARGUMENTS 🦋

• pdev — the ds2482 client pointer 💜 this is your little handle to the device, the whole reason we're here fr fr.
• cmd — the command you're sending. and bestie, it has to be one of these four, no substitutions:
  • DS2482_CMD_WRITE_CONFIG
  • DS2482_CMD_1WIRE_SINGLE_BIT
  • DS2482_CMD_1WIRE_WRITE_BYTE
  • DS2482_CMD_1WIRE_TRIPLET
• byte — the data to send 🌈 literally just the byte going along for the ride with the command.

---

🎀 RETURN 🎀

• -1 on failure 😭 (the vibe check did not pass)
• 0 on success ✨ (ate, no notes)

ngl, keep an eye on that -1 — it's the only heads-up you get that something went wrong.
