It would be great to better understand how this compares to RTOS and FreeRtos. E.g., if one wanted to build a baremetal version of a small programming language, like minilisp or Forth, what would one like to use ? I would like to understand where the various implementations of rtos have been used in a production settings, is this one stable enough to use ? This rtos seems pretty small, but documentation seems mostly in Chinese, e.g. https://github.com/RT-Thread/rt-thread/tree/cca2f40ae05a6eff108febbf39c7198a9c64c9ea/components/net/lwip/lwip-2.1.2 https://github.com/RT-Thread/rt-thread/tree/cca2f40ae05a6eff... Some code seems from older code bases: https://github.com/RT-Thread/rt-thread/blob/cca2f40ae05a6eff108febbf39c7198a9c64c9ea/components/net/lwip/lwip-2.1.2/src/api/api_lib.c https://github.com/RT-Thread/rt-thread/blob/cca2f40ae05a6eff... (C) 2001-2004 Swedish Institute of Computer Science. It's hard for a person new to embedded RTOSes to judge the stability or capabilities of a project like this. Overall, its great to see projects like this sprouting up!

There's a bunch of documentation (in english) at https://github.com/RT-Thread/rt-thread/blob/master/documentation https://github.com/RT-Thread/rt-thread/blob/master/documenta... One thing that stands out is that one of the selling points would be the inclusion of middleware etc. Internet of Things related software packages: Paho MQTT, WebClient, mongoose, WebTerminal, etc. Scripting language related software packages: JerryScript and MicroPython are currently supported. Multimedia related software packages: Openmv, mupdf. Tools packages: CmBacktrace, EasyFlash, EasyLogger, SystemView. System related software packages: RTGUI, Persimmon UI, lwext4, partition, SQLite, etc. That was surprising as I thought the key point was a small footprint. I haven'd dug in, a key point for me would be to create a minimal system, maybe just ethernet, wifi and bluetooth, and make those modular, so maybe just have a version with wifi only.
