Zephyr VS FreeRTOS

Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino. Source: 9 months ago

NimBLE comes from the Apache Mynewt real time operating system project. Mynewt is similar to other efforts like Zephyr. It continues to be maintained in 2023 and issues posed to the Github repository go answered. Source: 9 months ago

I'm looking at https://zephyrproject.org/ as an alternative to esp-idf for a new project, as it enables compatibility with other boards, plus a simulator for debugging. Source: over 1 year ago

That whole caboodle is available in an SoC now. Likewise, Zephyr is replacing Linux, thank God. Source: about 2 years ago

Time to upgrade to something more minimal - https://zephyrproject.org/. Source: over 2 years ago

In this post, I will step through an example setup that shows how to debug a FreeRTOS application in the Visual Studio Code (VSCode) editor using QEMU to emulate an Arm Cortex-M3 microcontroller. No actual hardware is required for this example, except a laptop or desktop as your development environment. - Source: dev.to / about 1 year ago

Https://freertos.org/ for example is a popular OS, that has realtime capabilities and fits in 9KB of RAM. https://micropython.org is basically a µC OS too, understands Python 3 Syntax and works with 16KB of RAM already. It might appear more convoluted at first, but you can get it to be real-time too by following the same principles as in any RTOS (react to stuff by means of ISR, allocate memory only initially and...

Just mentioning but, you can port FreeRTOS to your MCU and compiler and you are done. All thats left is tell the RTOS what to do. Ofc there is alot to learn about rtos. FreeRTOS. Source: about 2 years ago
