Bare-metal vs RTOS in Embedded Systems

Should you go bare-metal or use an RTOS in your embedded project?

✅ Bare-metal → ultra-lightweight, minimal memory, predictable timing. Best for simple, single-purpose devices.
✅ RTOS → multitasking, priorities, and modular design. Ideal for complex apps with networking, logging, and deadlines.

Trade-off: bare-metal = efficiency but less scalable; RTOS = overhead but better structure and concurrency control.
