💖 __adis_write_reg_16 — the Kernel API Manual page, but make it make sense 💖

okay so bestie, we're in the Kernel API Manual, section 9, and the star of the show is __adis_write_reg_16. the name literally tells you the whole vibe: it writes 2 bytes to a pair of registers, and it does it unlocked 🔓✨ (yes, "unlocked" is part of the deal — that's the underscore-underscore energy, iykyk).

✨ NAME ✨

__adis_write_reg_16 — Write 2 bytes to a pair of registers (unlocked)

like. that's it. that's the whole job. two bytes, two registers, no lock. slay. 💅

🎀 SYNOPSIS 🎀

int __adis_write_reg_16 (struct adis *adis , unsigned int reg , u16 val
);

it hands you back an int, so like, it's gonna tell you how it went. main character behavior fr fr.

🌸 ARGUMENTS 🌸

  • adis — The adis device. this is your little device buddy, the whole reason we're here 🫶

  • val — Value to be written. the actual 2 bytes going in. this is the payload, the moment, the whole point ✨
