Feel free to explore wilfriedvoss.com at your own pace—no subscription is required.
A substantial amount of the material on this website is freely available to anyone who visits. My goal is to share practical information about CAN Bus, SAE J1939, NMEA 2000, embedded systems, and related technologies—not to put everything behind a paywall.
However, subscribing does have its advantages.
A free subscription provides access to additional technical content, allows you to follow ongoing projects as they develop, and gives you the opportunity to participate through comments and questions. For readers who want to go deeper, a paid subscription provides access to more specialized engineering material and technical reports.
The basic idea is simple: read freely, subscribe if you find the site useful, and consider a paid subscription if you want access to the more advanced material.
Read Without Subscribing
You are welcome to browse the publicly available articles, projects, and resources without creating an account or providing an email address.
Public content will continue to be an important part of wilfriedvoss.com. It provides an opportunity to explore the site, discover topics that interest you, and decide whether you would like to follow future developments.
There is no obligation to subscribe.
Free Subscription
A free subscription provides access to additional material that is available only to subscribers.
This is particularly useful for ongoing projects such as CAN Bus Embedded Development, which is being published as an online book in progress. New topics will be added regularly, existing material may be expanded or refined, and the structure will evolve as the project develops.
Subscribers can also participate. Comments and questions are welcome, and reader feedback may help identify subjects that deserve additional explanation or entirely new articles.
A free subscription also allows me to keep you informed about significant additions to the website. I do not intend to send an email every time a new page or article is published. Several additions may be made between subscriber updates, allowing the website to grow without unnecessarily filling your inbox.
And, of course, there is no charge for a free subscription.
Paid Subscription
The paid subscription is intended for readers who want full access to the technical material available on wilfriedvoss.com.
One of the primary benefits is complete access to the online books, including projects such as CAN Bus Embedded Development. These books are published progressively, with new chapters and topics added as they are completed. Paid subscribers can read the entire available content and follow each book as it develops.
Paid subscribers also receive access to more specialized material that goes beyond the regular articles. This may include detailed engineering reports, implementation guides, technical analyses, test results, downloadable reference material, and other resources intended primarily for engineers and developers working with these technologies.
In addition, paid subscribers receive a 50% discount on the eBook or paperback edition when an online book is subsequently released in traditional book form. This provides the opportunity to follow and read the book while it is being developed online and later obtain the completed edition at half the regular price.
Of course, paid subscribers also receive everything included with a free subscription.
The paid level is not intended to replace the freely available material on wilfriedvoss.com. It provides access to the deeper technical content and complete online books while also helping support the research, development, testing, and writing required to continue expanding the site.
An Evolving Technical Resource
wilfriedvoss.com is deliberately being developed as more than a collection of individual blog posts.
Projects such as CAN Bus Embedded Development are designed to grow over time. Articles will be interconnected, existing material can be updated as technologies change, and reader questions can lead to additional subjects and explanations.
That approach also means the distinction between public, free-subscriber, and paid material will continue to evolve as the website grows.
Whether you choose to read without subscribing, become a free subscriber, or support the site through a paid subscription, you are welcome here.
The objective remains the same: to build a useful, practical, and continuously developing resource for people working with CAN Bus and embedded systems.
