STRUCT LED_PATTERN(9)

💖 struct led_pattern(9) 💖

okay so bestie, welcome to the struct led_pattern page — this is a chunk of the Kernel API Manual and it is literally the entire personality of a blink pattern, no cap. It's a tiny struct, only two members, but it's giving main character energy because it's the thing that tells a LED how to dance. 🕺✨

✨ NAME ✨

struct led_pattern — pattern interval settings 🎀

That's it. That's the whole vibe. It's the little struct that holds one step of a lighting pattern, and honestly? iconic.

---

🌈 SYNOPSIS 🌈

struct led_pattern {
    u32 delta_t;
    int brightness;
 };

like… two fields. two. and yet so much power. 😭💅

---

🦋 Members 🦋

• delta_t — the pattern interval delay, in milliseconds. so basically "how long does this step of the pattern last" — the timing of the whole thing. ⏱️
• brightness — the pattern interval brightness. the actual glow level for this step. how bright are we shining, bestie? 🔥

ngl, delta_t is a u32 and brightness is an int, and yes, that's exactly what the manual says, so we're keeping it exactly like that. 🫶
