Top 23 C Microcontroller Projects

  • MicroPython

    MicroPython - a lean and efficient Python implementation for microcontrollers and constrained systems

    Project mention: Where can I start testing python on real-life objects? | reddit.com/r/learnpython | 2023-02-04

    The lowest friction way would probably be to get some microcontroller that can run MicroPython.

  • lvgl

    Embedded graphics library to create beautiful UIs for any MCU, MPU and display type. It's boosted by a professional yet affordable drag and drop UI editor, called SquareLine Studio.

    Project mention: Embedded gui interfaces | reddit.com/r/embedded | 2023-01-30

    Have you considered https://lvgl.io ?

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Platform where developers build real-time applications for analytics, IoT and cloud-native services. Easy to start, it is available in the cloud or on-premises.

  • zephyr

    Primary Git Repository for the Zephyr Project. Zephyr is a new generation, scalable, optimized, secure RTOS for multiple hardware architectures.

    Project mention: Git archive generation meets Hyrum's law | news.ycombinator.com | 2023-02-02

    I think that's uncharitable. Almost no one realized these things were being generated. We all assumed that links to github's "releases" were just links to files because they look like links to files! Here's one to Zephyr 3.2.0: https://github.com/zephyrproject-rtos/zephyr/archive/refs/ta...

    You pull that and get a tarball that is presented to the world as an "official release". Looks like a file. Acts like a file. It's a file.

    So now your package manager or reproducible build engine or whatever needs a reference to the "official source code release", and what do you point it to? That file, obviously. It's right there on the "release" page for the download. And of course you checksum it for security, because duh.

    Then last week all of a sudden that file changed! Sure, it has the same contents. But the checksum that you computed in good faith based on the official release tarball doesn't match!

    If there's a misunderstanding here, it's on github and not the users. They can't be providing official release tarballs if they won't guarantee consistency. "As documented", this feature was a huge footgun. That's bad.

  • littlefs

    Use u8g2, awesome library, very flexible, works with everything.

  • circuitpython

  • nuttx

    Apache NuttX is a mature, real-time embedded operating system (RTOS)

    Project mention: Integrating rustix on NuttX | reddit.com/r/rust | 2022-12-08

    Hi Rust experts, we are willing to integrate rustix on NuttX RTOS, the initial effort was done by rustix author: https://github.com/bytecodealliance/rustix/tree/nuttx but it hit the wall since we don't know the right way to integrate cargo with the old-school NuttX's Makefiles. Any help or suggestion is welcome. More about NuttX here: https://nuttx.apache.org and here: https://nuttx.apache.org/docs/latest/

  • PikaPython

    PikaPython - Python runs with only 4KB of RAM, zero dependencies, easy to bind with C. Similar project: MicroPython, JerryScript.

    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.

  • embox

    Modular and configurable OS for embedded applications

    Project mention: Query: Alternatives to Zephyr? | reddit.com/r/embedded | 2022-03-21

    Look at Embox (https://github.com/embox/embox). It can run on EFM32ZG with 32kB ROM 4kB RAM

    +1 littlefs, we have used it in production, and it ran pretty well. One more option is reliance edge, it has nice GUI configuration tool, but it distributed over GPLv2
