stm32h7_adc_check_selfcalib(9)

🌸 stm32h7_adc_check_selfcalib(9) — from the Kernel API Manual, bestie 💅

okay so picture this: you're deep in the kernel, flipping through the manual, and you land on stm32h7_adc_check_selfcalib(9). Welcome. This is the whole page, and yes, I'm gonna walk you through every single bit of it ✨

---

💖 NAME 💖

stm32h7_adc_check_selfcalib — literally just checks the linear calibration status. That's the vibe check. That's the whole job. 🎀

---

✨ SYNOPSIS ✨

int stm32h7_adc_check_selfcalib (struct iio_dev *indio_dev );

One function, one argument, returns an int. no cap, that's it 🦋

---

🫶 ARGUMENTS 🫶

• indio_dev — the IIO device instance. like, the actual device we're checking up on. main character energy 💜

---

🔥 DESCRIPTION 🔥

So this is the function you call when you need to know "has linear calibration actually been done or not?" — that's the entire point of it.

It returns true if the linear calibration factors are already saved in private data, or if a linear calibration has already been done at the boot stage. Either way: calibrated, bestie, we're good 😭👑

That's literally the description. Short, sweet, iconic. periodt.
