💅 cpufunc.h — the cpufunc.h(3avr) glow-up

okay bestie, welcome to cpufunc.h 🎀 — this is the AVR-LibC manual page for it, section 3avr, and yes it's short, but short and iconic is a whole genre. no cap.

✨ NAME ✨

cpufunc.h — literally just that. the header. the moment. the file itself 🦋

✨ SYNOPSIS ✨

🌸 Macros 🌸

here's what's living in here as a macro, and it's giving minimalism:

#define _NOP()
#define _MemoryBarrier()

🌸 Functions 🌸

and the functions, bestie, presented in full, exactly as written, don't @ me:

void ccp_write_io (volatile uint8_t *__ioaddr, uint8_t __value)
void ccp_write_spm (volatile uint8_t *__ioaddr, uint8_t __value)
not me putting these in a code block with full respect for the exact parameter names 💀 volatile uint8_t *__ioaddr and uint8_t __value — untouched, unedited, unbothered. periodt.

so real quick vibe check on what you're looking at:

  • _NOP() — a macro, no arguments, takes nothing, gives nothing. it's the lowkey-est thing here 🙈
  • _MemoryBarrier() — also a macro, also no arguments. same energy, different name.
  • ccp_write_io — a function taking a volatile uint8_t *__ioaddr and a uint8_t __value, returning void. three things to remember, and you got this 🫶
  • ccp_write_spm — same shape fr fr: volatile uint8_t *__ioaddr, uint8_t __value, returns void. the sibling. the duo. 👑

✨ Author ✨

okay so nobody wrote this in the human sense — it was generated automatically by Doxygen for AVR-LibC from the source code. the source code is the author. the source code is the main character. we're all just reading its diary 💜

and that's the whole page, bestie, we ate and left no crumbs 💅✨

this was cpufunc.h(3avr) from AVR-LibC, Version 2.2.1 — mwah, go write some firmware, ily 🧚🌸💖
