What Is RP2040 Bare Metal Programming?
Understanding Bare Metal Programming
Bare metal programming refers to writing code that runs directly on hardware without an operating system or high-level abstraction layers. This allows developers to control hardware components at the lowest level.
It is commonly used in embedded systems, robotics, aerospace, and performance-critical applications.
Why RP2040 Is Used
The RP2040 microcontroller is popular because it offers strong performance, flexibility, and low-level hardware access. It is ideal for learning how microcontrollers work internally and how software interacts with physical systems.
Assembly Language Fundamentals
