Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Anyone Waiting on BT Auracast?
Hey folks. Anyone out there waiting for BT Auracast? It was announced June 2022, and immediately struck me as must have.
I lost my earbuds, but it seems ridiculous to get a replacement without Auracast, seems like surely if I'm going to make a decent sized purchase like that it needs to support group playing. I want to tune into the radios of other people on the metro or on the bus, want to be able to watch a movie on the plane with someone.
Auracast was announced in June 2022. Anyone else out there struggling with expectations here? I'm really hoping the product announcement season that's right around the corner had a good number of Auracast announcements.
Side note, a ton of it is over my head but it's been so so fun tuning in every once and again to see how Zephyr's Bluetooth Audio work is going. Just wild now much has gone into this! https://github.com/zephyrproject-rtos/zephyr/commits/main/subsys/bluetooth/audio

VisionFive 2 ROM addresses for Zephyr RTOS
I am working on adding support for VisionFive 2 in Zephyr RTOS. I have created a device tree by referencing the starfive linux, patches of hifive_unmatched FU740 SoC and patches of BeagleV Starlight.

Adding support for visionfive2 in zephyr rtos
We are unsure on how to proceed further with this error. We have opened a github discussion regarding the same issue.

Learning to write device drivers using C/C++ in Zephyr OS
Then there are samples. Look through it for anything useful. RC522 uses SPI, so getting that to work would be a good first step.

Building with cmake can't find cross-compile objcopy
Hey, I've been trying to build an app with cmake+ninja instead of west to integrate it into a larger build system and everything works correctly except for the final stage where it uses `/usr/bin/llvm-objcopy` instead of the `${CROSS_COMPILE}` one it tries to find here.

Arduino Joins Zephyr Project
Zephyr has a lot of good points, but I really wish it didn't use Kconfig. Getting a working config seems to be mostly a matter of copying an already working example. It might be okay for hardware side of things, but it's a really bad at software/feature dependency.
Set https://docs.zephyrproject.org/latest/build/kconfig/tips.htm... and the issue: https://github.com/zephyrproject-rtos/zephyr/issues/52575. And don't even get me started on trying anything to group options together.

PlatformIO and Zephyr is a bad idea
In this thread u/ikravets explained that there hasn't been much demand for Zephyr, which is why they aren't doing anything with it, and in this pull request Zephyr decided to no longer recommend PlatformIO in their documentation.

Zephyr RTOS RAM Tracing
The answer is always in the source: https://github.com/zephyrproject-rtos/zephyr/blob/bdaac354f4cb0ad91d952c2f6941c16240d84da2/subsys/tracing/tracing_backend_ram.c

Microsoft opens sources ThreadX RTOS used in Raspberry Pis
It is not open source. The source code is open but with an evaluation, i.e. proprietary license:
https://github.com/azure-rtos/threadx/blob/master/LICENSE.tx...

Eclipse ThreadX
License looked alright, until I came across this: https://github.com/azure-rtos/threadx/blob/a8e5d0946c31385ff...

PlatformIO and Zephyr is a bad idea
Portability, mainly. Zephyr runs on a wide variety of architectures and 450+ variations of popular boards are already supported upstream (adding more often being pretty easy). In your particular example, your own preferences with regards to building on top of open-source software may play a role too. For example, Azure RTOS is not open source, and its license will, among other things, prevent you to use it in production on other hardware than what's listed herehere. So easily moving from one hardware vendor / SoC to the other might be a problem, should this be a requirement (and it kind of becomes one for a lot of people in these times if silicon shortage)

Linux vs. QNX/VxWorks for a climate control system - Education
Honestly as long as you use one of the supported MCU families ThreadX is probably a better choice these days given how much better NetX is over FreeRTOS’ TCP implementation.

As a guess, what percentage of embedded projects actually need the R in RTOS?
Azure RTOS/ThreadX is only free on approved pre-licensed uCs, but with that said, there's a ton of devices covered by it so it's an option for a lot of projects.

What are some cool modern libraries you enjoy using?
I'm interested in something equivalent to tx_byte_pool but for non-embedded usage where I want a custom allocator for defined pools. Do you know if mimalloc can do this? I see it has custom heaps, but I didn't see any functions to create one from raw memory.
