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.

Project mention: Curious to see if everyone pays full price for sonos products or are there ways to get discounts? Would appreciate any guidance to save $s. | reddit.com/r/sonos | 2023-02-03
If you’re interested, you might be able to get Airplay 1 & 2 support by running shairport-sync on your pi.

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.

Project mention: I need some help, I want to "rotate" the screen by 180 degrees. I am just printing some simple data on the screen for my modified nerf gun. Any advice on how to do it? | reddit.com/r/arduino | 2022-12-28
Use u8g2, awesome library, very flexible, works with everything.
-
printf
Tiny, fast, non-dependent and fully loaded printf implementation for embedded systems. Extensive test suite passing.
Project mention: Nolibc: A minimal C-library replacement shipped with the kernel | news.ycombinator.com | 2023-01-22Seems unlikely. My spot check of the the two vfprintf implementations shows no flow from one to the other, and shows that part of the Cosmopolitan code has an older lineage than nolibc.
The nolibc source has many reference to copyright held by "Willy Tarreau", under LGPL-2.1 OR MIT license, with a copyright date starting in 2017.
The string "Tarreau" does not exist in the Cosmopolitan library, so that's a strong negative there. Let's look closer.
The file organization is quite different. And so is the implementation. So that's another negative.
Compare the vfprintf in nolibc at https://elixir.bootlin.com/linux/v6.2-rc4/source/tools/inclu... (a 'minimal vfprintf()') with the one in cosmopolitan starting at https://github.com/jart/cosmopolitan/blob/master/libc/stdio/....
Right away we can see nolibc places many functions in the same file while Cosmopolitan uses a one-function-per-filename organization.
Cosmopolitan's fvprintf locks the file (which nolibc doesn't need to do) then calls vfprintf_unlocked which calls __fmt at https://github.com/jart/cosmopolitan/blob/master/libc/fmt/fm... , which is the actual implementation. It look very different from NOLIBC's.
Okay, so perhaps that's they way now but not at the beginning?
We can also go back to Cosmopolitan's original implementation and see how vfprintf goes through https://github.com/jart/cosmopolitan/blob/c91b3c50068224929c... to call "palandprintf", which https://github.com/jart/cosmopolitan/blob/c91b3c50068224929c... says is copyright "Marco Paland" from 2014-2019.
That's a few years older than the start of nolibc, available from https://github.com/mpaland/printf , and part of https://github.com/embeddedartistry/libc , a "libc targeted for embedded systems usage".
Thus, multiple factors seem to agree that nolibc code is not used in the Cosmopolitan library.

Project mention: Tilck – A Tiny Linux-Compatible Kernel | reddit.com/r/patient_hackernews | 2023-01-08
-
I don't know if it's the best place to post that but on the meson subreddit there is not much people. I want to include the library INIH (which use meson too) to my project but I don't know how.

Project mention: Xilinx HLS AXI4-Lite registers don't update right away | reddit.com/r/FPGA | 2022-08-15
Here is the top level function. It is a modified version of the convolution HLS provided in one of Xilinx's Vitis tutorials. I've run into a similar problem for other HLS IP where the AXI4-Lite registers don't update right away. ``` void Filter2DKernel( const float coeffs[MAX_COEFFS], float factor, short bias, unsigned short width, unsigned short height, unsigned short stride, hls::stream &input_stream, hls::stream &output_stream) {

xboot
The extensible bootloader for embedded system with application engine, write once, run everywhere.
-
MuditaOS
Mobile operating system based on FreeRTOS™ optimized for E Ink displays - developed for Mudita Pure minimalist phone
Maybe the MuditaOS for the Mudita Pure phone based on FreeRTOS is free (GPL) succesor ?
-
libhydrogen
A lightweight, secure, easy-to-use crypto library suitable for constrained environments.
Project mention: libsodium-wrappers on a Raspberry Pi Zero W | reddit.com/r/raspberry_pi | 2022-04-22See if you can use this library instead of libsodium, as it'll probably work on your raspi zero: https://github.com/jedisct1/libhydrogen (Node bindings: https://github.com/trampi/node-libhydrogen-binding)
-
luos_engine
Open-source and real-time orchestrator for cyber-physical-systems, to easily design, test and deploy embedded applications and digital twins.
After much research and experimentation, Ada discovered Luos. Luos is a framework for building and managing microservices on embedded devices. It provides a set of tools and libraries that make it easy to develop, deploy, and manage microservices on embedded systems. Ada was thrilled with Luos and knew that it was the perfect solution for her client's project.

libc
libc targeted for embedded systems usage. Reduced set of functionality (due to embedded nature). Chosen for portability and quick bringup. (by embeddedartistry)

Project mention: My Descent 1 setup with modern trims | reddit.com/r/retrobattlestations | 2023-01-06
The USB4VC is a RPi based project allowing you to send modern mouse, keyboard and joystick signals to a vintage computer. In this case, a wireless bluetooth Playstation 4 gamepad is used. More info on its github: https://github.com/dekuNukem/USB4VC

QuarkTS
An open-source OS for embedded applications that supports prioritized cooperative scheduling, time control, inter-task communications primitives, hierarchical state machines and CoRoutines.
Project mention: Looking for a non-preemptive (cooperative) multi-tasking library in C. | reddit.com/r/embedded | 2022-07-10 -
Project mention: DeckMTP, a decky plugin for transfering files via USB | reddit.com/r/SteamDeck | 2023-02-02
You might also notice that there's no SD card mount in the config. That's because it's added during runtime, since uMTP-Responder supports it. They show example usage on their github, and I show example usage of that in my start script, where it detects the SD card. The runtime way is temporary, though, and it disappears when it restarts.
