ab8500_gpadc_ad_to_voltage(9)

💅 ab8500_gpadc_ad_to_voltage 💅

okay so this is a page straight out of the Kernel API Manual, bestie, and it's about one (1) function that takes your raw ADC number and turns it into an actual voltage. glow-up for integers, fr.

✨ NAME ✨

ab8500_gpadc_ad_to_voltage — Convert a raw ADC value to a voltage

like, that's the whole gig. raw number in, voltage out. slay.

---

🦋 SYNOPSIS 🦋

int ab8500_gpadc_ad_to_voltage (struct ab8500_gpadc *gpadc , enum
ab8500_gpadc_channel ch , int ad_value );

it returns an int, she takes three args, and yes the spacing is exactly like that, don't @ me, that's literally how it's written 😌

---

🎀 ARGUMENTS 🎀

• gpadc — the GPADC instance 💖 like, the actual little guy you're talking to.
• ch — the sampled channel this raw value is coming from 🌸 important, because the raw number only means something if you know which channel it came from, iykyk.
• ad_value — the raw value 🫶 that's it. that's the number. the raw one. the before picture.
