Liquid State Machine

Ground-station software, Fill Cart firmware, and P1AM OTA tooling.

Architecture

• base_station/ — FastAPI operator UI, LabJack DAQ, run storage, firmware tools.
• fill_cart/ — P1AM state machine and P1 rack valve/igniter outputs.
• p1am_updater/ — second-stage A/B Ethernet OTA updater.
• firmware_libs/P1AMOta/ — shared OTA boot-state support.

The base station talks to both devices directly:

• P1AM: 192.168.8.50 — state machine and actuators.
• LabJack T7: 192.168.8.51 — sensor acquisition.

The P1AM does not control the LabJack.

Quick start

cd base_station
uv sync --locked
uv run gui

Pages:

• / — live telemetry.
• /state — Fill Cart state control.
• /configuration — DAQ signal graph.
• /runs — Record/Stop and run archive.
• /devices/p1am — P1AM health, rack initialization, and restart.
• /devices/labjack — LabJack connection and device health.
• /logs — structured system events.
• /settings — appearance preferences.

The operator UI uses a global 260 px sidebar that collapses to a 52 px icon rail. Device/navigation state lives there; route-specific controls stay on their pages.

Firmware

Normal updates are Ethernet-only:

cd base_station
uv run system
uv run ota

USB is only for bootstrap/recovery:

uv run upload --port /dev/cu.usbmodemNNNN
