Dion

Embedded software engineer
dion@tweedegolf.com

Dion is an experienced Rust and embedded software developer who has worked in a lot of projects. The experience comes in the form of knowledge about a plethora of communication technologies (including LoRaWAN, LTE and UWB), a focus on well-architected code and a drive for innovation. His skills and creativity can take a project from an idea to a full product and allow him to give advice about what is possible within the given project bounds and about how to maximize the results.

Dion has created and maintains several open-source projects:

nrf-modem: An async Rust wrapper around the modem library for the nRF9160
sequential-storage: A crate for storing data in flash memory with minimal need for erasing pages
device-driver: A toolkit to write better device drivers, faster

He has also contributed to:

statime: A PTP stack written in Rust
embassy: An async runtime for embedded devices in Rust
dw1000-rs: An extensive driver for the DW1000 chip

In his spare time, his creativity tends to find musical outlets. Dion plays the piano and regularly works on electronic music.

The hunt for error -22

This article is a linear retrospective of how we searched for and eventually fixed a hard-to-find bug in our embedded software. If you're only interested in the outcome, then make sure to read the last three sections.

Rust is rolling off the Volvo assembly line

In my job I get to speak to lots of people about Rust. Some are just starting out, some have barely ever heard of it, and then some people are running Rust silently in production at a very large company in a very serious product.

Sequential-storage: efficiently store data in flash

While using a full-blown filesystem for storing your data in non-volatile memory is common practice, those filesystems are often too big, not to mention annoying to use, for the things I want to do. My solution?

I've been hard at work creating the sequential-storage crate. In this blog post I'd like to go over what it is, why I created it and what it does.

Statime

Statime is an initiative of Tweede golf, an open-source implementation of the Precision Time Protocol (PTP) in Rust.

High-precision timing is part of crucial networking infrastructure. With Statime we provide a memory-safe alternative for existing implementations.

The first milestones of the project were kindly co-funded by the NLnet Foundation.

Statime is part of Project Pendulum. In July of 2023 the Sovereign Tech Fund invested in Pendulum, securing development and maintenance in 2023, and maintenance and adoption work in 2024.
