Is STM32 a RTOS?

FreeRTOS is a free and open source real-time operating system (RTOS) that runs on many popular microcontrollers, including STM32. In 2017, Amazon took control of the FreeRTOS project and now provides regular maintenance and support.

Should I use RTOS?

An RTOS will often be used when there are more interrupt sources, more functions, and more standard communications interfaces that need to be supported. If the application is <64KB in size, an RTOS is not necessary. Conversely if, the applications is 1 MB, an RTOS will likely be used.

What is RTOS good for?

Multitasking, alone, is enough reason to use an RTOS in many systems. It allows you to break a complex problem into simpler pieces (tasks) and focus on the development of each task rather than on scheduling when things run. It also makes it easier to partition work among members of a team.

Why is FreeRTOS popular?

FreeRTOS is tiny, which can lower your cost of goods considerably. When you’re working on these small MCUs, you get ecstatic when you can save a few bytes — space is always tight. Next, FreeRTOS is ubiquitous. It runs on pretty much any small, modern MCU.

How much RAM does FreeRTOS use?

The RTOS kernel itself required about 5 to 10 KBytes of ROM space when using the same configuration as stated for the FAQ “How much RAM does FreeRTOS use?”. How long does FreeRTOS take to boot? FreeRTOS, OpenRTOS and in most cases SafeRTOS are supplied as source code for static linking into the users application.

Where is FreeRTOS used?

Amazon provides an extension of FreeRTOS, referred to as a:FreeRTOS. This is FreeRTOS with libraries for Internet of things (IoT) support, specifically for Amazon Web Services. Since version 10.0. 0 in 2017, Amazon has taken stewardship of the FreeRTOS code, including any updates to the original kernel.

When RTOS is not needed for embedded system?

It is good to know RTOS as it is being used in many applications. But it is not mandatory for embedded software. Similarly it is good to have knowledge of simple PCB design concept but not mandatory for embedded software professional. One can design small products with simple bare board programming .
