Which is better, RTOS or bare metal for MCU programming?
Benefits of RTOS vs Bare Metal for MCU Programming? Please note: This question specifically mentions two RTOSes but is more generic and can probably be answered by anybody who has written C code for embedded RTOSes before, and had their software run directly on MCUs.
Can you write C code for embedded RTOSes?
Please note: This question specifically mentions two RTOSes but is more generic and can probably be answered by anybody who has written C code for embedded RTOSes before, and had their software run directly on MCUs. I am interested in learning more about embedded RTOSes and writing applications for them.
How does RTOS context switching work for ARM Cortex-M MCUs?
To understand how RTOS context switching works for ARM Cortex-M MCUs, it’s critical to have foundational knowledge about the primitives the architecture provides to make it possible.
What do you mean by context switch in RTOS?
The operation of switching from one task to another is known as a context switch. A Real Time Operating System ( RTOS) will typically provide this functionality. Having a foundational knowledge of how the core of an RTOS works can be a valuable skill set for an embedded engineer to have.
How does the RTOS Kernel switch between tasks?
Applications designed for use with a real time operating system (RTOS) are structured as a set of autonomous tasks. The RTOS kernel will switch between tasks as necessary to ensure the task with the highest priority that is able to run is the task given processing time.
How is the scheduling policy used in RTOS?
The scheduling policy is the algorithm used by the OS to decide which task should be executing at any moment in time. The scheduling policy is designed to meet the objectives of the OS—which for an RTOS is to provide a timely response to real world events. The application designer must assign a priority to each task.
