Top 23 C IoT Projects

  • Netdata

    Real-time performance monitoring, done right!

    Project mention: How to claim nods/ connect to cloud Netdata with agent in Docker on Synology NAS? | reddit.com/r/netdata | 2022-11-17

    What can change between installs is under /var/lib/netdata (see https://github.com/netdata/netdata/issues/2516). This is why we want this directory mounted from the host. /var/cache/netdata is even more important, as it holds the db with the metrics. Still, worst case scenario is that you'll have in cloud a dead node along with the live node, so yhere's no need for a fresh install.

  • TDengine

    Project mention: How do you all monitor ambient temps for your drives? Cooking drives is no fun... I think I found a decent solution with these $12 Govee bluetooth thermometers and Home Assistant. | reddit.com/r/DataHoarder | 2022-11-28

    My fridge and other homelab gear is plugged into Sonoff S31 smart plugs (flashed with Tasmota) + Prometheus endpoint exposed), so I can monitor the current and graph that.

  • TimescaleDB

    An open-source time-series SQL database optimized for fast ingest and complex queries. Packaged as a PostgreSQL extension.

    Project mention: Embedded Web Server for electronic devices | news.ycombinator.com | 2022-11-14
  • rt-thread

    RT-Thread is an open source IoT operating system.

    Project mention: The Most Popular Open Source IoT Operating System from China | news.ycombinator.com | 2022-11-14

    There's a bunch of documentation (in english) at 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:

  • Zigi

    Close all those tabs. Zigi will handle your updates.. Zigi monitors Jira and GitHub updates, pings you when PRs need approval and lets you take fast actions - all directly from Slack! Plus it reduces cycle time by up to 75%.

    Project mention: Looking to setup GitHub actions pipeline with google test, memory checker, documentation generator, etc. | reddit.com/r/cpp_questions | 2022-11-10

    The Zephyr RTOS has a large range of workflows that you can check out and you check how they run in the actions tab.

  • jerryscript

    Ultra-lightweight JavaScript engine for the Internet of Things.

    Project mention: Arduino Announces MicroPython Support | reddit.com/r/programming | 2022-11-12
  • wasm3

    🚀 The fastest WebAssembly interpreter, and the most universal runtime

    Project mention: The Pine Formula | news.ycombinator.com | 2022-08-03

    > This product family will never run Linux, as developers will need to develop a new firmware from scratch. This is obviously not a problem for the earbuds, but a big limitation for the player

    Perhaps not Linux, but I suspect there would be a place here for a Unix-like platform that feels familiar. If for example we could get wide-adoption of something like the JVM or wasm3 [0] on these platforms, code could become quite portable, despite wildly different architectures.

    For example, Apache's NuttX [1] (that I first learned from Lupyuen, a guy making great progress working with Pine64 products).

    > Processing wise, this chip is well sufficient for TWS headphones, but very inadequate for an audio player. It will not drive a good screen, it nor run high-resolution flacs or (probably?) support a high-quality, high-bandwidth codec. In fact, a first generation iPod Nano (retailing for $149 in 2006) had 16MB RAM, so over 16 times what the PinePod would offer. In fact, even the features of any custom firmware are limited from so little memory

    I wouldn't call it time just yet. Displays can be interacted with intelligently (to reduce pixel bandwidth) and ultra high quality audio codecs offer diminishing returns, especially when you don't have a DAC or headphones to make the most of them.

    My advice to Pine64 would be this:

    1. Consolidate your product lines. The Pinebook is just a slower Pinebook Pro, just go with the Pinebook Pro. The PineTab is just a Pinebook without the keyboard, again I would consolidate this with the Pinebook Pro and just make the keyboard detachable.

    2. The SBCs should just go straight into the device, thus creating a clear upgrade path for future products. If you want a PineBook Pro running Quartz, just swap the boards (of course with daughter boards for USB expansion, display driver, power, etc).

    3. Don't be afraid to kill off products. The Pinebook and PineTab have never seen a new release. The PinePhone appears to be taking a back seat to the PinePhone Pro. The PineCube is basically DoA due to the processing power struggling to process the camera image.

    More generally, try to do fewer things, but do them well.

  • RIOT

    RIOT - The friendly OS for IoT (by RIOT-OS)

    Project mention: Programming arduino in actual C | reddit.com/r/embedded | 2022-10-20

    Alternatively, you can also write your code in an RTOS. They often have scripts that make flashing and debugging easy. One that I personally like, and also supports Arduino, is RIOT-OS.

  • wasm-micro-runtime

    WebAssembly Micro Runtime (WAMR)

    Project mention: Learning Embedded rust | reddit.com/r/rust | 2022-11-18

    A very interesting solution for high level interface access by less professional developers could be seen in pikascript, which works even on very small devices. WAMR is another project with similar capabilities. Both of them can be very well combined with core infrastructure realized as embedded rust code.

  • mongoose-os

    Mongoose OS - an IoT Firmware Development Framework. Supported microcontrollers: ESP32, ESP8266, CC3220, CC3200, STM32F4, STM32L4, STM32F7. Amazon AWS IoT, Microsoft Azure, Google IoT Core integrated. Code in C or JavaScript.

    Project mention: Toit – A Language Designed for Microcontrollers | news.ycombinator.com | 2022-06-08

    As long as Toit is licensed under the GNU Lesser General Public License v2.1, I am unlikely to consider using it. By contrast, MicroPython is licensed under the MIT License (MIT).

    As others have noted, Toit seems like a bad name. I suppose non-French speakers will tend to inadvertently mispronounce Toit.

    Getting traction is hard. In my opinion, having a restrictive license and a bad name make it less likely Toit will gain traction. Finally, Toit licensing reminds me of Mongoose OS https://github.com/cesanta/mongoose-os#mongoose-os---an-iot-....
