Detailed Description

PT_BOARD_multi_gui – Live plots for PT_BOARD_Multi_Send

Receives DAQv2-Comms SENSOR_DATA packets over UDP from PT_BOARD_Multi_Send,
decodes them, and displays real-time voltage plots for each PT (1–10).

Ensure the firmware's receiverIP matches this machine's IP (or use 192.168.2.20)
and that the GUI listens on port 5007 (PT board). Actuator_Testing uses 5006 so
both can run together.

  pip install -r requirements.txt
  python pt_multi_gui.py [-p 5007] [-a 0.0.0.0]

  On macOS, if you get a segfault: use PyQt5 instead of PyQt6
  (pip install PyQt5; this script will try PyQt5 if PyQt6 is unavailable).
