💅 PCALED(4) — like, the LED dimmer era 💅

okay so bestie, gather round, because we're talking about pcaled today — the Philips PCA9532/PCA9552 GPIO LED dimmer and honestly? she's iconic. this is the manpage for the pcaled kernel driver, and yes i'm gonna walk you through every single line because that's what besties do 🫶

✨ SYNOPSIS ✨

like, here's how she shows up in your kernel config, fr fr:

pcaled* at iic?

🌸 DESCRIPTION 🌸

okay so the pcaled driver? it provides support for the Philips PCA9532 and PCA9552 GPIO controllers. and these aren't just any controllers, bestie — they're specifically optimized to dim LEDs in 256 discrete steps. two hundred and fifty-six. that's not a vibe check, that's a whole vibe curriculum. the way that 256 steps of dimming just... exists? obsessed. 💖
