Simple Control Loop in Embedded Systems

Most embedded systems start simple — with a control loop.

✅ One while(true) loop runs forever
✅ Reads inputs → processes logic → updates outputs
✅ Lightweight, predictable, and easy to debug

But as tasks grow (timers, comms, multitasking), it quickly becomes harder to manage, that’s when interrupts or RTOS come in.

The simple control loop = the foundation of embedded software.
