💖 boot.h 💖

okay so bestie, welcome to boot.h, straight out of the 3avr manual — this is the AVR-LibC header page that's basically a whole group chat full of #defines, and we're gonna go through every single one together because you deserve the full tea, not a summary 🌸

No cap, it's a lot of macros. But you're a main character, you got this. 💅

✨ NAME ✨

boot.h — that's it, that's the name, she's short and iconic and she knows it 🎀

✨ SYNOPSIS ✨

🎀 Macros 🎀

here's the whole squad, every last one, exactly as written, no edits, no gatekeeping, fr fr 🫶

  • #define BOOTLOADER_SECTION __attribute__ ((__section__('.bootloader'))) — the entire definition is right there in the open: an __attribute__ with a __section__ of '.bootloader', and honestly? slay, no secrets 🌈
  • #define boot_spm_interrupt_enable() — the name is the whole plot, bestie: SPM interrupt, enable 🦋
  • #define boot_spm_interrupt_disable() — same energy, opposite verb: SPM interrupt, disable 💜
  • #define boot_is_spm_interrupt() — the "is it though?" check of the family 👑
  • #define boot_rww_busy() — asks the question "RWW busy?" and that's literally all it's called ⭐
  • #define boot_spm_busy() — the SPM-flavoured version of the same vibe check 🔥
  • #define boot_spm_busy_wait() — busy check but make it wait 😭
  • #define GET_LOW_FUSE_BITS (0x0000) — this one comes with a value baked in: 0x0000 ✨
  • #define GET_LOCK_BITS (0x0001) — and her value is 0x0001 🎀
  • #define GET_EXTENDED_FUSE_BITS (0x0002) — value: 0x0002, yes the numbers are all different, yes that matters 🌸
  • #define GET_HIGH_FUSE_BITS (0x0003) — value: 0x0003, completing the little 0x0000 → 0x0003 glow-up 💖
  • #define boot_lock_fuse_bits_get(address) — takes exactly one argument, and she calls it address 🧚
  • #define boot_signature_byte_get(addr) — one argument, but this one's named addr, not address, and we respect her choices 💅
  • #define boot_page_fill(address, data) — two arguments: address and data 🍓
  • #define boot_page_erase(address) — one argument: address 💀
  • #define boot_page_write(address) — one argument: address ⭐
  • #define boot_rww_enable() — takes nothing, gives enable energy 🌈
  • #define boot_lock_bits_set(lock_bits) — one argument named lock_bits 🫶
  • #define boot_page_fill_safe(address, data) — the _safe remix of the fill macro, same two arguments, address and data 😌
  • #define boot_page_erase_safe(address) — the _safe remix of erase, one address 💜
  • #define boot_page_write_safe(address) — the _safe remix of write, one address 👑
  • #define boot_rww_enable_safe() — the _safe remix of enable, still zero arguments sweets 🦋
  • #define boot_lock_bits_set_safe(lock_bits) — the _safe remix of the lock-bits setter, one lock_bits 🔥
lowkey the pattern is staring right at you: anything with a _safe twin has a twin, and the arguments match up one-for-one. that's not me guessing at behaviour, that's just reading the guest list 💖

(so the author is a robot, and honestly? the robot ate. no notes.) 🤖✨

and that's the whole page, bestie — you now know every macro, every argument name, every value, and every _safe variant, and you didn't skip a single one, which is genuinely iconic behaviour 👑

this was AVR-LibC, Version 2.2.1, serving you boot.h from the 3avr manual — mwah, go forth and compile 💖🎀🦋
