 Let me give you second last slide, and that's about the Friartos footprint. So you can see a table that gives you a comparison with other RTOs, and the size of the ROM and RAM implementation without any other functionality. So depending on the setup and the included functions of the Friartos, you can see that it's coming somewhere between 2.7 and 3.6 kilobytes in size. And the RAM used by a pure Friartos is 200 bytes. All objects add extra on top. But that's what you can expect from this RTOs. Speaking about others, you have got a CMX, RTX kernel from a CMX company. A little bit bigger. You have got a Kyl RTX operating system implemented by Kyl and supported by Kyl Microvision, which is a little bit smaller and as well very nice. And then you have got examples of other operating systems like Micro-COS 2 and MOS. Again, fully supported and running on STM32s. I would say that most of them have a very similar functionality. All of them support task switching. You can see whether they have a primitive or cooperative modes. All of them support message queues and mutexes, semaphores. So all the standard elements of the RTOS world. They may differ in licenses, so you need to study a little bit. Nowadays, the very modern development is, for example, on the Zephyr OS, which is equipped with quite a big ecosystem of different plugins and drivers.
