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.

Crash! And now what?

Imagine you've just deployed an embedded device in the world and of course, you have tested it thoroughly and it works. To monitor the device, you've set up some logging.

During the Rust meetup titled "Run Rust Anywhere" in Utrecht, August 2022, Dion talked about his Embedded Rust work.

For the last couple of months, we've been working on a Rust implementation of the Precision Time Protocol called Statime ("statim" is Latin for immediately), and we're proud to announce the completion of the first phase of the project.

It is no secret that we at Tweede golf love Embedded Rust, you can read about it in our other blog posts. But we thought it'd be fun to hear from the community too!

It's time for another technical blog post about async Rust on embedded. This time we're going to pitch Embassy/Rust against FreeRTOS/C on an STM32F446 microcontroller.

Let me introduce myself, I'm Dion Dokter, 24 years old (as of writing) and the newest member at Tweede golf (TG). I've always been into computers and started writing desktop software and games in 2013, embedded software in 2015, and started with Rust in 2019.
