ENUM AD7793_REFSEL(9)

💅 enum ad7793_refsel(9)

okay so bestie, real talk — this is from the Kernel API Manual and it's literally just a little enum that tells the AD7793 driver which reference voltage to use. that's it. that's the whole vibe. but it's an important vibe, so let's go 🫶

---

✨ NAME ✨

enum ad7793_refsel — the AD7793 reference voltage selection, aka "which voltage am I measuring against" the enum 🎀

---

🌸 SYNOPSIS 🌸

enum ad7793_refsel {
    AD7793_REFSEL_REFIN1 ,
    AD7793_REFSEL_REFIN2 ,
    AD7793_REFSEL_INTERNAL

};

look at her. three constants. no cap, she's simple and she knows it ✨

---

🦋 Constants 🦋

• AD7793_REFSEL_REFIN1 — an external reference voltage, applied between REFIN1(+) and REFIN1(-). external ref says hi 👋
• AD7793_REFSEL_REFIN2 — another external reference, this one applied between REFIN2(+) and REFIN1(-) (yes, note that it pairs REFIN2(+) with REFIN1(-), that's not a typo bestie, that's just how she is 💀). Only valid for AD7795/AD7796 — so if you're on a different chip, this one's not for you, sorry 🙈
• AD7793_REFSEL_INTERNAL — the internal 1.17 V reference. built-in, lowkey iconic, no external parts required 👑
