Embedded Bytes #189: Zephyr’s Devicetree, Simulating Firmware, Claude Code and More

Sponsored by partners who share our mission to advance embedded excellence.

Issue #188

Dear ,

Welcome back to the Embedded Bytes newsletter!

In this issue, you’ll find:

I also want to bring your attention to a new sponsor for the newsletter, Cesanta, which produces the Mongoose Wizard for developing Embedded Web Servers with a Web UI builder.

I think it’s super cool and would recommend you check it out and watch their short demo. I’m currently evaluating using this at least in my Embedded Software Academy courses.

A few reminders:

The 2026 Embedded Online Conference Call for Talks is closing this Friday December 12th. You can submit your abstracts and talk ideas here.

The last Newsletter for the year will come out on December 24th. In case you’ll already be out of the office, I wish you, your colleagues and family Happy Holidays and a great start to the new year!

Happy Coding,

Why Claude Code for Firmware Development Matters

You might think that using Claude Code for Firmware development doesn’t matter.

Sadly, your thinking would be misplaced. AI Assistants like Claude Code can help solve a large number of problems that I see developers and teams struggle with everyday.

For example, I see firmware teams drowning in technical debt while racing to ship a buggy product, hoping that they’ll be able to go back and fix things IF they can just get through this delivery.

I see mountains of legacy code nobody understands. Reference manuals measured in thousands of pages that no one reads. Toolchains that break when Mercury’s in retrograde or when the wind blows in just the right direction.

AI coding assistants promise help . . .
