STRUCT STM32_ADC_VREFINT(9)

💅 struct stm32_adc_vrefint(9) — like, the whole page, bestie

okay so you're reading the Kernel API Manual (that's the manual name, periodt) and the page is struct stm32_adc_vrefint(9). It's giving very niche, very ADC, very internal-reference-voltage core. Let's go ✨

---

✨ NAME ✨

struct stm32_adc_vrefint — literally the stm32 ADC internal reference voltage data. that's her whole job 🎀

---

🦋 SYNOPSIS 🦋

like, here's the shape of her, verbatim, don't touch:

struct stm32_adc_vrefint {
    u32 vrefint_cal;
    u32 vrefint_data;
 };

ok yes the closing brace has a lil extra space, we do not gatekeep, we do not "fix" it 💅

---

🌸 Members 🌸

• vrefint_cal — the vrefint calibration value, and she gets it from nvmem. that's the factory-issued vibe check, iykyk 🧚
• vrefint_data — the vrefint actual value. the real one. the main character reading 🔥

👑 SEE ALSO 👑

ok this is the friend group and honestly? it's a big friend group. highkey iconic 💖

ngl bestie there are no options, no env vars, no exit statuses, no signals and no bugs listed on this page — it's just a struct and her two u32 fields. no cap. that's the entire serve 💀
