Bare Metal Programming
Bare metal programming refers to writing software that runs directly on hardware without an operating system or any abstraction layers. This involves direct control over CPU registers, memory, and peripherals, typically using low-level languages like C or assembly. It is essential for embedded systems, firmware, bootloaders, and real-time applications where performance and resource constraints are critical.
Developers should learn bare metal programming when working on embedded systems, IoT devices, or microcontrollers where operating systems are unavailable or too resource-intensive. It is crucial for firmware development, device drivers, and real-time systems that require deterministic timing and direct hardware access. This skill is also valuable for understanding computer architecture and low-level system operations.
