Rapid embedded with Zephyr RTOS

It’s time for another foss-gbg! On November 16th Tobias Olausson of Elektronikutvecklingsbyrån will talk about Zephyr RTOS.

Zephyr is an RTOS with ”batteries included”. It comes with built-in support for a large number of boards, and includes many libraries useful for the firmware developer. Furthermore, Zephyr uses KConfig and device trees to select features and describe hardware.

The large ecosystem together with the flexibility of device trees, makes Zephyr an excellent RTOS for rapid development. I will show how we work at EUB where we can write almost all the firmware before we have the actual hardware available, and how you can do the same!

There will be demos! There will be hardware! Hopefully there won’t be any smoke puffs coming from the hardware 🙂

There will be something to eat and drink as well, feel free to join from 16:30 onwards. The talk starts at 17:00-ish.

Using FOSS with RISC-V

It’s been long, but the wait is over. For this autumn’s first foss-gbg, Klas Nordmark of 2550 Engineering will talk about working with RISC-V.

RISC-V is an open standard ISA that’s completely royalty free and available under open source licenses. Klas will talk about his experiences with getting free samples of RISC-V cores through the OpenMPW initiative. General RISC-V introduction will be covered as well as some specifics for the chips that Klas worked with.

The main focus of the talk will be about how to use the tooling available for RISC-V (which is all FOSS) as well as the process on how to work with it. There will also be hardware samples to look at!

HaleyTek will supply both venue and fika! The talk will start at around 17:00, fika will be available from 16:30.

Attend through the meetup: https://www.meetup.com/foss-gbg/events/296103555/

Klas’ slides from the talk are available at Google Docs

foss-north lightning talks online

This Sunday we ran the first virtual sessions of foss-north. First out were the lightning talks. This was for two reasons – it is the stress case for the infrastructure – and it is easier to find a group of lightning talk speakers one week earlier than to move the 1h talks.

First of all I want to say that the infrastructure worked very well! We have some rough edges to to take care of, but in general the technology worked.

You find the actual talks below. Following the links you find slides as well as recordings of the sessions.

Develop better software with usability testing by Andreas Nilsson
Running Android on the Raspberry Pi by Chris Simmonds
The Yocto Project 10 minute quick-start guide by Ron Munitz
Getting started with your smart, connected, vehicle project by Dimitris Platis
Seven years in Tibet^W^Wat Home by Kristoffer Grönlund
Linux on RISC-V by Drew Fustini
Singularity container platform by Anders Björklund

foss-north 2020 virtual lightning talks

On Sunday March 22 foss-north 2020 will go virtual with a set of lightning talks. This will be the dress rehersal before the big virtual event March 29 – April 1. Join us and enjoy the fun!

foss-north postponed

It is with great regret that I have to announce that foss-north 2020 has been postponed due to the COVID-19 situation.

It will be replaced by a virtual event during the planned dates (March 30-31), and a physical event during the fall.

We regret any inconvenience that this causes our guests and sponsors. At the same time we appreciate the great support of our sponsors who unanimously support us in these difficult times.

Details will be shared at https://foss-north.se/2020/ as we learn more.

foss-north 2020 Schedule

We have a provisional schedule for #fossnorth (still waiting for some speakers confirmations). Check it out here: https://foss-north.se/2020/schedule.html

Slides from React

Last meet the foss-gbg group met at Edument who celebrated their 10 years birthday. We listened to two great talks about React held by David Waller and Marc Klefter. And we got cake – a first for foss-gbg :-).

You can download David’s slides from here. The code used by Marc in his talk can be downloaded from here.

Thank you everyone for attending and big thanks for David and Marc for their presentations. Next meeting will be foss-north 2020. See you there!

foss-gbg 2020-02: React

The next foss-gbg is arranged in collaboration with Edument. They are celebrating their 10th anniversary and want to do so by spreading their knowledge around React!

The talk will be held by two speakers: David and Marc.

React Architectural Patterns – David Waller

Join us in walking through a broad array of React architectural patterns! We’ll show problems and solutions for most concerns harrying the modern React developer. This includes topics like file organisation, error handling, providing dependencies, global state management, child component output, and more.

Data Fetching with Suspense – Marc Klefter

Suspense is poised to become the essential method for loading components’ asynchronous resources in the near future; this practically oriented talk will position you at the forefront of the latest developments in implementing better performant React applications.

Read more about the seminars – https://www.edument.se/en/page/react-on-tour-eng.

As usual, participation is free of charge, but you need to reserve your seat. Get your ticket here: https://www.meetup.com/foss-gbg/events/268297331/.

2019-10: The Game Programming Event

Yesterday we met to learn about game programming. Anders Björklund started with a presentation on SpriteWorld – the project that got him into open source. You can find his slides here.

After that Johan Thelin did a live session showing Godot. He started in 2D and ended in VR. All the example code is available on his github, and the slides are here.

Again – big thank you to everyone who joined in – and big thank you to Unionen for the nice venue and food!
