Your First Bare-Metal Project on ESP32 | Blinking of LED
Bare-metal programming refers to writing software that runs directly on the hardware — without the support of an operating system (OS), middleware, or high-level abstraction layers. It’s the most fundamental form of embedded development, where you, as the developer, manage the hardware resources manually using register-level programming.
