Zepyhr RTOS (MCU OS) has support for WireGuard VPN now 🔒

„The networking stack also gains support for WireGuard VPN, enabling secure, low-overhead tunneling directly on your Zephyr devices. WireGuard is known for its simplicity, speed, and strong cryptography, making it an ideal fit for resource-constrained embedded devices that need secure remote management or encrypted data transport.“

Now it is slightly disagreeing with Zephyr's implementation in that Register at 0x01 is Reserved in the Datasheet but listed as `GEST_ID` in zephyr.

Now, Zephyr doesn't actually use the register, so that's fine I suppose. #embedded #zephyrRTOS

I realize this is a stretch, but has anyone worked with #Zephyr on #NixOS? I'm getting an error because GCC pulled in by Zephyr is dynamically linked and NixOS does not like that.

Moving beyond k_msgq in #ZephyrRTOS. 🚀

If you’re still manually routing every message between threads using standard queues, you might be creating unnecessary coupling in your #Firmware.

ZBus (the Zephyr Bus) brings a powerful Pub/Sub model to the RTOS level. It allows you to:
✅ Decouple data producers from consumers.
✅ Add observers (like loggers) without touching your core logic.
✅ Simplify many-to-many communication.

A course that teaches #kicad, C coding, git, #zephyrrtos, #ngspice and practical, hands-on #electronics. Yes, it's pretty easy to see why Mark Palmeri and I got along.

We get into hands-on labs, verification & validation, regulated-device thinking, and why using real tools matters if you want students ready for industry.

Mark also explains more about his ongoing
Tympanometer project with the Duke BME Design Fellows program.
