✨ stm32f4_i2c_write_msg(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a little kernel-side function page and honestly it's short and sweet — no cap, it's giving "one job, does it well" energy 🎀

🌸 NAME 🌸

stm32f4_i2c_write_msg — literally just fills the data register in write mode 🫶 that's the whole vibe.

🦋 SYNOPSIS 🦋

void stm32f4_i2c_write_msg (struct stm32f4_i2c_dev *i2c_dev );

yep, that's it, that's the whole call. one argument, no return value, in and out 😌

👑 ARGUMENTS 👑

  • i2c_dev — the controller's private data 💖 this is your struct stm32f4_i2c_dev *, the little bundle of state that tells the function which I2C controller we're talking to.

⭐ DESCRIPTION ⭐

so what does it actually do? it fills the data register with the I2C transfer buffer 🔥 that's it. that's the function. write mode, data register, buffer goes in. iconic behavior, zero drama 🌈
