@Middleware & OS and @MCU, MPU & Firmware, do you build devices that leverage embedded virtualization? I'm interested to know how many "IoT devices" utilize virtualization these days.

Haven't used virtualization in production until now
Just learning purposes

What are the processors you've deployed on in production? I'm interested because I wonder a lot of time if the devs even know what they're deploying on these days?

Hi @kristof-at-embeetle if you don't mind may I know from where you've got the membrane overlay printed on Embeetle's tiny scarab? Also, which software do you use for the design

kristof-at-embeetle•10/9/24, 10:33 AM

Hi @Umesh Lokhande ,
I used https://www.jrpanel.com/
They have a great online system to enter your files.

The Beetle Board is open source. You can find the files for the graphical overlay here:

RRenuel Roberts when working with Zephyr OS for embedded systems, what do you find most benefici...

Boss lady•10/9/24, 10:42 AM

Zephyr OS has become a popular choice for embedded systems due to its real-time performance, modular architecture, extensive hardware support, and built-in security features. Designed for time-sensitive applications such as industrial automation and medical devices, Zephyr ensures that tasks are executed predictably, meeting strict timing requirements.

I prefer it because of its modular design allowing developers to tailor the OS to fit specific project needs, keeping it lightweight and efficient for resource-constrained environments. Zephyr also supports a wide range of hardware architectures like ARM, RISC-V, and x86, offering flexibility for multi-platform projects. Through its use of the Hardware Abstraction Layer (HAL) and device trees, it simplifies hardware configuration without code changes.

Also it takes security as a core feature, with integrated support for secure boot, trusted execution environments, and memory protection, making it a strong option for IoT and connected devices. Zephyr also includes cryptographic libraries and network security features, ensuring safe communication over networks.

If you would like to know more about zephyr you can check out the Zephyr Project GitHub repository and the Zephyr documentation. You can also access the Zephyr OS PDF guide for a comprehensive overview of its capabilities.

Hey guys, what do you think about the future of Open-source contributions in embedded systems. Are corporate interests slowly undermining the true spirit of open-source contributions in embedded systems? Can big companies and the open-source community ever find common ground, or are we heading toward inevitable conflict over control and innovation? @Middleware & OS and @MCU, MPU & Firmware

ke7c2mi•10/9/24, 4:21 PM

Flip that round - open source has over time filled more and more of the niche. Things were far more proprietary a decade ago.

barafael•10/9/24, 4:23 PM

I strongly believe and also weakly hope that open source software systems are and will be simply better in many metrics.

CChoRam I want to know why this question now? Has anything happened in recent times?

Dtynin•10/9/24, 4:37 PM

not per say tho...but I hope the future of open-source contribution in embedded system should be community driven as opposed by some folks that thinks otherwise tho

Ming•10/9/24, 6:12 PM

Looking at things like the Linux Kernel....
The most commits to the kernel come from corporations (Microsoft is actually one of the biggest contributors to the Kernel!).
A lot of the kernel maintainers are employed by corporations.

However, none of that stops individuals from contributing their bits to the kernel.

I see it as a positive that enterprises can commit things that improve software for their use case and as is the spirit of open-source - everybody benefits.

If an enterprise tried to block commits to an open-source project, then with the 'cancel culture' the bad PR would be bad for their bottom line and so very quickly counter-productive.

CChoRam Zephyr is FOSS right? Is it becoming closed source?

Ming•10/9/24, 6:53 PM

Zephyr is run by the Linux Foundation so is not going closed source anytime soon!

Hi Community ! Myself Mogal Roshan Baig , done Bachelors in Computer Science and Engineering currently working to enhance my skills on embedded systems , and Iam very much interested in open source projects. Any help or suggestion would be appreciated. Iam totally beginner please suggest me some new opensource projects.
Thanks.

Marvee Amasi•10/10/24, 6:32 AM

Hi Mogal, nice for you to join us

. Since you are starting out in embedded systems and want to get into open source projects, I will suggest that you look into some beginner friendly platforms like Arduino, ESP32, or STM32. They have active communities and plenty of projects to contribute to. You can explore open source repositories on GitHub related to IoT, robotics, or home automation great places to start

matthewflynn_•10/10/24, 8:30 AM

Hi there. I've been working as a .net dev and want to use the

Iot.Devices.Imu

Iot.Devices.Imu

library to calibrate and use a acceleormeter on a project I am building.

I have had issues with a bug using an

MPU-6050

MPU-6050

. I went to buy another in case it was a dud and was sent a

Adafruit TDK InvenSense ICM-20948 9-DoF IMU (MPU-9250 Upgrade) (STEMMA QT / Qwiic)

Adafruit TDK InvenSense ICM-20948 9-DoF IMU (MPU-9250 Upgrade) (STEMMA QT / Qwiic)

as they were out of stock.

I've tried writing my own class to get the data and calibrate but I my readings seem to really vary in the sample set on the Gyro side?

Does anyone know where I can find a details of the unit so I can make sure I'm reaidn ghte right data? (I can share my code if anyone wants to look).

Camila_99$$•10/10/24, 9:42 AM

Hi @matthewflynn_ welcome!
I’d be happy to take a look at your code to help pinpoint the calibration issues. For the ICM-20948, you might want to check the specific register map and data sheet to ensure you're reading the right values, as it differs a bit from the MPU-6050. Could be helpful to review your Gyro calibration routine too.

Hey guys, what do you think? Is the use of Proprietary software better than Open-source software in Critical systems such as those used in healthcare, aviation, or government? I'd like to know your judgments when it comes to critical systems. Let me hear your view.
