FAQ
Embedded Systems FAQs.
Questions we get before kicking off microcontroller C/C++ firmware and custom PCB layout engineering.
- Bare-metal firmware executes a continuous C loop without an operating system, providing maximum speed and low memory usage for simple devices. An RTOS (Real-Time Operating System like FreeRTOS) introduces multi-tasking, mutexes, and queues for complex hardware with multiple sensors.
