## What it is
A collection of bare-metal ARM assembly and C examples for Raspberry Pi boards, from the BCM2835-based Pi 1 through the Pi 3, with no operating system involved. It serves as educational material for learning low-level embedded programming on the Raspberry Pi hardware.

## Use cases
- learn bare metal programming on raspberry pi
- arm assembly examples for bcm2835
- blink an led without an operating system
- understand raspberry pi peripheral base addresses
- write a kernel.img from scratch
- study low-level embedded arm development

## When to choose
- you want to learn bare-metal ARM programming on Raspberry Pi hardware
- you need concrete examples of GPIO, timers, and peripherals without an OS
- you are teaching or self-studying low-level embedded systems

## When to avoid
- you want a maintained library or framework with a stable API
- you need support for Raspberry Pi 4 or newer boards
- you prefer well-documented, organized code over rambling notes and legacy directories

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, embedded, documentation
- domain: embedded-systems, education, hardware, operating-systems
- platform: embedded, cpp
- tags: bare-metal, arm, raspberry-pi, assembly, examples, bcm2835, low-level-programming, linux
