init_display(9)

💖 init_display(9) — Kernel API Manual 💖

okay so we're out here in the kernel API manual, and this page is init_display — she's the one who initializes the display controller, and honestly? iconic entry-level main character energy ✨

---

🌸 NAME 🌸

init_display — literally just: initialize the display controller 🖥️💅

---

✨ SYNOPSIS ✨

int init_display (struct fbtft_par *par );

like yes bestie that's the whole signature, she's not complicated 🫶

---

🎀 ARGUMENTS 🎀

• par — the FBTFT parameter object 💖 this is your little bag of everything the driver needs, hand it over and we're good

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — most of the commands in this init function set their parameters to the same default values that are already in place after the display has been powered up. so like, a lot of it is "yes queen, we know, you're already like that" 💀

the main exception to this rule is the pixel format, which would default to 18 instead of 16 bit per pixel. so yeah, that one actually matters 👀

nonetheless (love that word), this sequence can be used as a template for concrete displays, which usually need some adjustments. so think of it like a starting fit, not the final look — you'll be tailoring it, fr fr 🧵✨

---

🔥 RETURN 🔥

• 0 on success 🥳
• < 0 if an error occurred 😭
