stm32f4_i2c_isr_error(9)

💅 stm32f4_i2c_isr_error(9) — from the Kernel API Manual, bestie

Okay so picture this: it's a kernel API manual page, it's giving <purple>serious documentation energy</purple>, and the star of the show is a little interrupt routine for I2C bus errors. Yes, that one. Let's get into it 🫶

✨ NAME ✨

stm32f4_i2c_isr_error — literally the interrupt routine for I2C bus error, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

irqreturn_t stm32f4_i2c_isr_error (int irq , void *data );

Not me just dropping the signature like it's nothing 😭 it's exact, copy it character for character, no cap.

---

🎀 ARGUMENTS 🎀

• irq — the interrupt number, hi bestie 👋 this is which interrupt we're talking about
• data — the controller's private data, iykyk, it's the little bag of stuff that belongs to this controller ✨

🌸 SEE ALSO 🌸

First up, the source-of-truth file situation — this lives in the kernel file ./drivers/i2c/busses/i2c-stm32f4.c, and there's a struct situation going on there too 👑

Then the whole friend group, because nobody does it alone:

• stm32f4_i2c_msg(9)
• struct stm32f4_i2c_dev(9)
