STRUCT BQ256XX_STATE(9)

💅 struct bq256xx_state(9) — a Kernel API Manual moment

okay so real talk, we're in the Kernel API Manual bestie, and this page is literally about struct bq256xx_state. yes that's the whole name. the NAME section is blank. no description. nothing. it's giving mysterious main character energy and honestly? we respect it. 🎀

---

✨ NAME ✨

struct bq256xx_state — and that's it. that's the name. the description slot is lowkey empty, no cap. moving on before we cry 😭

---

✨ SYNOPSIS ✨

here's the whole vibe, copy-pasted exactly because we do NOT play with struct definitions:

struct bq256xx_state {
    u8 vbus_stat;
    u8 chrg_stat;
    bool online;
    u8 wdt_fault;
    u8 bat_fault;
    u8 chrg_fault;
    u8 ntc_fault;
 };

seven little fields. that's the whole struct. she's compact, she's iconic, she's the state of your BQ256xx charger. 👑

✨ Members ✨

okay so here's the group chat roster of every field, and what each one means — keep these names EXACT, they're load-bearing 🫶

• vbus_stat — the VBUS status, decoded according to BQ256XX_CHARGER_STATUS_0. that's the port power situation.
• chrg_stat — the charging status, also according to BQ256XX_CHARGER_STATUS_0. how's the charge going? this tells you.
• online — the PG status per BQ256XX_CHARGER_STATUS_0. it's a bool, so like… yes or no, are we plugged in and good. 🦋
• wdt_fault — watch out, watchdog fault! this one comes from BQ256XX_CHARGER_STATUS_1.
• bat_fault — battery fault, per BQ256XX_CHARGER_STATUS_1. something's up with the battery, not slay.
• chrg_fault — charging fault, again from BQ256XX_CHARGER_STATUS_1. the charging is not charging.
• ntc_fault — the TS fault, according to BQ256XX_CHARGER_STATUS_1. TS = the temperature-sense situation, and this field is telling you it's faulted.

ngl bestie, all four fault fields (wdt_fault, bat_fault, chrg_fault, ntc_fault) are just "is this broken?" flags, and they all vibe off BQ256XX_CHARGER_STATUS_1. the first three fields vibe off BQ256XX_CHARGER_STATUS_0. iykyk 💅
