I wonder why the comparison table does not include FreeRTOS or Zephyr. From a high level view, I don't really what's really different for RIOT OS

  I would read the extensive list of features and look at the code first before hurling content-free FUD. It even supports Arduino too. https://github.com/RIOT-OS/RIOT/tree/master/cpu https://github.com/RIOT-OS/RIOT/tree/master/cpu

    Found some answers on another HN thread : https://news.ycombinator.com/item?id=19016945 https://news.ycombinator.com/item?id=19016945 But asking questions is not spreading FUD in my book

    Not comparing to Zephyr, which ticks all the same boxes, is absolutely a problem. And I would argue that Arduino support nowadays is a negative, not a positive. Arduino support means that you are going to do a bunch of things to support 8 and 16 bit systems that look absolutely silly on 32 bit systems. And, it's not even clear that Arduino systems are actually cheaper or lower power than ARM Cortex-M4 systems anymore--which negates the advantage of Arduinos.

      I completely switched to the Adafruit Feather M4 series for my hobby electronics about 5 years ago. Each board might be a little more expensive than a base Arduino, but they are way more powerful and have a lot of great features.

        If you want to go "budget", STM32 hardware (like the common "blue pill" STM32F103C8 board) is priced comparably to a knockoff Arduino, if not cheaper.
        • pantalaimon 7y ago
          You can now get much more powerfull STM32F411CEU6 boards for the same price.
          • duskwuff 7y ago
            Which boards are you thinking of? "Blue pill" STM32F103C8 boards are $2 to $3, if you're willing to run the risk of getting a cloned microcontroller. (The clones are actually quite usable for most purposes.)
            • pantalaimon 7y ago
              The clones even tend to have more memory. But I was thinking of those boards: https://aliexpress.com/item/4000103610226.html https://aliexpress.com/item/4000103610226.html (also supported by RIOT btw https://github.com/RIOT-OS/RIOT/pull/12778 https://github.com/RIOT-OS/RIOT/pull/12778)

                Oh, those! I have one of the F401 models -- I didn't know there was a F411 variant, though, nor that they've gotten so cheap. There might be a purchase in my future. :)

                Some clones even have chip errata fixed.
      • elcritch 7y ago
        Those M4's are handy! I use the Adafruit Itsy M4s. Wait does this support them?!
      • stevekemp 7y ago
        For a similar reason I switched over the Wemos Mini-D1. In my case having onboard Wifi is usually more important to me than having extra I/O ports.

        Not sure why you're being downvoted. ISAs like avr, 8051, and msp430 aren't really any crazier than arm. The archs that are a pain aren't because they're 8/16 bit.
      • bsder 7y ago
        Just talking about memory--far pointers, banks that have to be switched in and out, non-uniform memory accesses, etc. Putting those into a compiler puts an enormous amount of surface into a compiler that is completely useless on 32-bit architectures.

      ...and then you can start to use mbed.

  The website hasn't been updated in a while, back then Zephyr wasn't thing yet…
  • anon4242 7y ago
    But FreeRTOS has been around for quite some time with wide support among HW manufacturers, so why not include that?
    • pantalaimon 7y ago
      FreeRTOS doesn't come with drivers or a networking stack, it's more a building block than a whole operating system.
