What is Bare-Metal?
Bare-Metal Firmware
Bare-metal firmware runs directly on the microcontroller with no operating system, giving full control and minimal overhead — well suited to simple, resource-constrained, or hard real-time applications.
Without an RTOS's scheduler, the developer manages timing and concurrency directly. Bare-metal maximizes performance and minimizes memory use, but grows harder to maintain as a project's complexity increases.
