Episode Summary
- IPv8: An actual IETF draft for IPv8 is making the rounds, with the very serious idea of moving to 64-bit IP addresses.
- ZMK in Framework Laptops: Framework’s latest keyboard work is powered by ZMK, bringing another nice Zephyr-adjacent project into mainstream laptop hardware.
- Windows 9x for Linux: wsl9x runs a Linux kernel as a Windows 95 application, which is exactly as delightfully weird as it sounds.
- STM32H7RS: ST’s STM32H7RS is a powerful Cortex-M7 MCU family built around the idea of booting from internal flash and running larger applications from external memory.
- Zephyr on Pebble: A community project is exploring PebbleOS on Zephyr, showing another fun path for bringing older embedded platforms back to life.
- OpenDeck: OpenDeck is a Zephyr-based platform for building MIDI controllers, with support for wired MIDI, USB, Bluetooth, and custom hardware.
- New Architectures: Work is underway to add Hexagon and TriCore architecture support to Zephyr, expanding into DSP and automotive-oriented use cases.
- Serial IPC Backend: A new serial IPC backend adds a COBS-based transport for communication between processors over serial links.
- HTTP/3 and PTP: HTTP/3 support is already following the recent QUIC work, while PTP IEEE 802.3 transport adds more time-sensitive networking capabilities.
- Robotics in Zephyr: A proposed Robotics Working Group and a kinematic tree subsystem RFC point to growing interest in making Zephyr a stronger platform for robotics.
- Seeed COB LED Driver Board: Support for Seeed Studio’s COB LED Driver Board led to a broader discussion about PWM examples and documentation.
- Shell Aliases: Shell aliases should make long Zephyr shell commands easier to use.
- Testplan Discovery: A proposed testplan discovery overhaul aims to make PR testing smarter, faster, and more relevant to the files that actually changed.
- BeagleBadge: The BeagleBadge brings Zephyr to a capable e-ink badge platform.
- CRSF Remote Controller Support: CRSF input support adds a protocol used by drones, rovers, and ExpressLRS-style remote-control systems.
- Native LoRaWAN Backend: A native LoRaWAN backend is in progress, starting with LoRaWAN 1.0.4, OTAA, Class A, and EU band support.
- AD-APARDPFW-SL Shield: The AD-APARDPFW-SL shield adds single-pair Ethernet experimentation to Zephyr.
- ADP5360 PMIC: ADP5360 support is a good example of Zephyr’s multi-function device model, exposing PMIC features such as charging, fuel gauge, GPIOs, and regulators.
