ca8210_get_ed(9)

💅 ca8210_get_ed — Kernel API Manual ✨

okay so bestie, this is ca8210_get_ed from the Kernel API Manual, and it's honestly one of the more chill functions in the whole ca8210 saga. It literally just goes "hey, what's the energy on the channel right now?" and tells you. That's it. That's the function. 🎀

---

🌸 NAME 🌸

ca8210_get_ed — returns the measured energy on the current channel, like, at this exact instant in time. right now. not a second ago, not in a sec. now. ⏱️✨

---

🦋 SYNOPSIS 🦋

int ca8210_get_ed (struct ieee802154_hw *hw , u8 *level );

like yes that's the whole signature, she's compact and she knows it 💅

---

💖 ARGUMENTS 💖

• hw — the ieee802154_hw of the target ca8210. this is your main character — the hardware you're asking about 🌈
• level — the Measured Energy Detect level. this is where the answer lands, so it's giving "output parameter" energy fr fr 📥

---

👑 RETURN 👑

returns 0 or a linux error code. so like, either everything slayed or something went off and you get an error code back. no in-between, no cap. 💀

quick vibe check bestie: level is where the measured value goes, so don't hand her a null and expect magic. and the return is 0 or a linux error code — check it, always. 💅

and that's the page!! this one ships out of ./drivers/net/ieee802154, dated October 2026 — so like, mark your calendars, she's got a whole month named after her era 🌸💜 mwah, go measure some energy, ily, bye!! 🫶✨
