Writing Your Own Gadget with Zephyr OS

on YouTube ↗38m

" summary

Shows how to make Zephyr OS–based embedded boards present as USB gadgets to a host PC, with concrete examples: exposing Zephyr-hosted IEEE 802.15.4 and Bluetooth radios to Linux as radio adapters, and presenting a Zephyr SoC as a USB Ethernet controller using ECM or RNDIS to act as an IP bridge. Covers related OS-side driver approaches — a custom Linux driver for IEEE 802.15.4 over USB, using standard OS drivers for USB classes like Bluetooth, and supplying Windows USB descriptors for RNDIS — and briefly touches on WebUSB for browser-based board access.
