Supports UTF-8 strings in application layer

Device tree language-independent

No native i18n for kernel or DSL

External tooling can adapt outputs

Primarily technical audience usage

Targeted at embedded developers

CLI and console-based tools

Documentation-driven learning

Simulation frameworks for accessibility

Community support for troubleshooting

No native GUI

Serial console and logging via printk

External visualization via connected host

Debug LEDs or hardware indicators

Optional dashboards for IoT telemetry

Kernel threads maintain execution state

Semaphores and mutexes manage shared resources

Timers handle delayed or periodic actions

Device tree overlays define persistent hardware configuration

Application state coordinated via APIs and kernel objects

Use structs, arrays, and kernel objects for structured data

Device tree nodes define hardware resource mapping

Memory optimization critical for constrained devices

Queues and FIFOs manage inter-thread data

Low-level drivers handle raw peripheral data
