ENUM ES58X_EVENT(9)

✨ enum es58x_event ✨

okay bestie, welcome to the Kernel API Manual page for enum es58x_event — it's giving "small enum, big feelings" 💅

---

💖 NAME 💖

enum es58x_event — the CAN error codes that the device hands back to you. no cap, that's literally it. 🎀

---

🌸 SYNOPSIS 🌸

enum es58x_event {
    ES58X_EVENT_OK ,
    ES58X_EVENT_CRTL_ACTIVE ,
    ES58X_EVENT_CRTL_PASSIVE ,
    ES58X_EVENT_CRTL_WARNING ,
    ES58X_EVENT_BUSOFF ,
    ES58X_EVENT_SINGLE_WIRE

};

(and yes, the spelling is CRTL in the source, not CTRL — we do not fix the icon's typo, we respect the icon's typo 🙈)

👑 Constants 👑

so here's the whole cast of characters, one by one, main character energy each:

• ES58X_EVENT_OK — no errors. everything's fine, the vibe check passed, we're thriving 🦋
• ES58X_EVENT_CRTL_ACTIVE — the active state: both TR and RX error count is less than 128. both of them. like a healthy friendship 💜
• ES58X_EVENT_CRTL_PASSIVE — the passive state: either TX or RX error count is greater than 127. so once either one tips over 127, that's the state we're in 😭
• ES58X_EVENT_CRTL_WARNING — the warning state: either TX or RX error count is greater than 96. not a crisis yet, but it's giving ⚠️ energy 🔥
• ES58X_EVENT_BUSOFF — bus off. periodt. that's the whole description 💀
• ES58X_EVENT_SINGLE_WIRE — lost connection on either CAN high or CAN low. one of the wires said "i'm out" 🙈

🧚 Description 🧚

for the extra details, bestie, please refer to ISO 11898-1:2015, section 12.1.4 "Rules of fault confinement". that's where all the real lore lives 📖✨
