Sheraton Gateway LAX, Los Angeles, California · United States · 2017
LayerOne 2017's electronic badge was a CAN-bus-focused STM32F4 conference badge with a TFT display, storage, USB device and host behavior, external CAN headers, audio output, rechargeable battery planning, PC-side CAN tooling, and J2534-adjacent software work.
Lifecycle
The badge-team details page names STM32F446/F405/F415-class LQFP64 support as the controller direction for the 2017 badge.
The development logs describe CAN logging, ECU reflashing experiments, J2534-adjacent PC software, NES emulator memory access over CAN, and PC-versus-badge gameplay ideas.
Project details describe a 2.2 or 2.4-inch DMA-driven SPI TFT display with ILI9341/45 support and SPI SD card storage.
The badge-team notes describe USB device support, USB host, HID or CDC behavior, and ST-Link V2/SWD programming expectations.
The project documents twin 1 Mbps CAN buses, two transceivers, external CAN headers, MITM or dual-logging breakout, and CAN-side badge focus.
Operational history
Software and protocol claims are kept to the public project statements rather than treating development notes as a complete release package.
The entry remains source-backed and image-free rather than copying official-page images, Hackaday CDN photos, video frames, or prototype screenshots without complete provenance.
The catalogue records the source-backed architecture and car-hacking direction while avoiding unsupported claims about every final shipped component, firmware image, or quantity.
