## What it is
A tutorial series with C example code for bare metal programming on the 64-bit Raspberry Pi 3, covering hardware interfacing like serial console, framebuffer, and MMIO. It targets hobby OS developers and explicitly excludes OS theory topics like memory management or multitasking.

## Use cases
- learn bare metal programming on raspberry pi 3
- write a freestanding C program for ARM64 hardware
- get started with hobby OS development on raspberry pi
- learn how to use MMIO and the serial console on raspberry pi
- draw to the framebuffer on raspberry pi without an OS
- set up a cross-compiler for bare metal ARM development

## When to choose
- you want hands-on examples of interfacing with Raspberry Pi 3 hardware in C
- you are new to bare metal or hobby OS development on 64-bit ARM
- you want to learn serial I/O, framebuffer graphics, and hardware peripherals without an OS

## When to avoid
- you want a full guide to OS theory like memory management, VFS, or multitasking
- you need 32-bit Raspberry Pi tutorials or C++ with a runtime library
- you need production-ready OS code rather than educational examples

## Facets
- artifact type: learning-resource
- maturity: stable
- function: developer-tools, embedded
- domain: embedded-systems, operating-systems, tutorials, hardware
- platform: embedded, cpp
- tags: bare-metal, raspberry-pi, arm64, osdev, tutorial, mmio, freestanding-c, linux
