Update the status label with the given message.

Start a timer to automatically turn off test mode after 5 seconds.

Update the Arduino image to show transmit animation when writing serial data, normal when not.

lat/lon → root-pixel coordinates that you can assign to widget.pos. Works regardless of OrbitMap letter-boxing.

Yield sample times [s] from t0 upward at steps of dt. By default the first sample is at t0+dt (matching many logs). Use include_zero=Tru

True if ISS is inside ZOE at time t_ephem: - ZOE does not apply if Z-belt (7 or 8) is active -> always False. - Otherwise, no

Check if start button should be enabled and update its state.

Reschedule the serial writer with the specified interval.

Reset the status label to the default message.

Position TDRS group labels dynamically based on satellite positions.

Ensure newline termination and call serialWrite once per update.

Run apt-get with non-interactive flags, auto-wait/repair, lean (no recommends).

Get database path with cross-platform handling.

Load current crew from SQLite into self.crew_data and refresh UI only if changed.

Test a specific LED animation.

Test a specific LED pattern.

Update the current location display and input fields.

Show or hide the transmit animation on the Arduino widget.

Update the state of all playback control buttons.

Get a fresh connection to the telemetry database.

pip install with Bookworm/Trixie system Python compatibility.
