Jul 1, 2025July 2025 monthly summary for HyperloopUPV-H8/adj: Delivered substantial improvements across vehicle control, data packet handling, safety sequencing, and testing. Strengthened cross-board reliability and scalability by implementing core state machine initialization and order ID synchronization, expanding packet infrastructure, and introducing comprehensive safety/order flows. Also advanced HVSCU integration, temperature handling, and control station alignment to enable safer operation and richer telemetry. Key achievements include: - Vehicle State Machine initialization with cross-board order ID synchronization (commits: 1c6a7510..., 8105864d..., 471ec219...) - Expanded Packet Infrastructure: added packets file path and extended packet set (commits: 15171102..., ee80a0a5...) - Safety and control enhancements: regulator orders, brake/unbrake orders, emergency stop order, and levitation distance variable (commits: 4ed0ece4..., 524859b3..., 37dc0387...) - Recovery state support and test sequencing: added recovery state order, integrated into states enum, and exposed recovery state variable; PCU/VCU/test run orders (commits: cfec84d5..., 4b4bcc95..., 65551e43..., 84d65c1b..., fdf60eed..., 5944165e...) - HVSCU integration/testing, SDC packet updates, and temperature/control station enhancements: updated HVSCU content, enum/packet naming changes, temperature packets, second temperature, and missing BMSL temps; control station variable alignment and cell metrics (commits: 5d0821bf..., d56fc2c2..., 9213b898..., 66773d35..., 0e18c115..., 35272422..., a414b091..., 4a995c31...) Business value and impact: these changes reduce cross-board conflicts, improve safety and telemetry, enable more robust automated testing, streamline data handling, and lay groundwork for scalable deployment across additional boards and configurations.
