About

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
  • stackdump: A set of tools to make memory dumps and read them out as a stack trace for crash reporting
  • statime: A PTP stack written in Rust

He has also contributed to:

  • embassy: An async runtime for embedded devices in Rust
  • stm32h7xx-hal: A hardware abstraction layer for the STM32H7 chips
  • 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.

About one year ago, Tweede Golf announced "Statime", a Rust implementation of the Precision Time Protocol (PTP). The result of that first phase was a working proof of concept. Quite a bit has changed since then.

Are we embedded yet?

Rust is maturing and every year more software is being made with it. In fact, Rust can be used as a competitor to C. In this article I will argue that this is now also the case for embedded Rust!
NLR, Royal Netherlands Aerospace Centre, invited embedded lead Dion to explain the benefits of programming in Rust to the company.

Statime

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

High-precision timing is part of crucial networking infrastructure. With Statime we aim to 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.

nrf-modem-nal

An embedded-nal implementation for the nRF9160 (built on top of the nrfxlib rust crate).

Other than exposing the NAL, it also implements enabling and disabling the modem when required automatically.
