Canonical software repos for devices and operations. Component index: Software (Software database).

Device software

• PDN/FDN Firmware & Data Node Core: pdn

Backend

• Alleycat Rust Server — Alleycat API server (Rust): GitHub · DeepWiki

Frontend / operations

• Mission Control
• Primary: MissionControl-Recoded
  • Legacy Mission Control Experimentation Repo: event-os

Architecture (embedded)

PDN and FDN firmware share a common direction:

• HAL (Hardware Abstraction Layer) — game logic stays stable across PCB/enclosure revisions.
• State machines — multi-stage experiences (duels, Posse chains, Shootout rings, FDN sessions) without nested one-off conditionals.
• Core library (goal) — extract shared embedded code so other event hardware can reuse the same patterns.

Custom OS on ESP32-S3 supports loading application modules; wireless mesh (ESP-NOW) carries duels and multiplayer topologies at festival scale.

Mission Control

Director’s console for live ops: send data to PDNs and FDNs in real time — on-screen messages, LED colors, haptics, and game state across the field. Supports planned beats (broadcast, infect/clear, scripted moments) and improvisation when the crowd does something unexpected.
