ui.ui_debug module

Debug readout screen for the Romi robot UI.

Displays a single-shot snapshot of key sensor and system values over the serial terminal whenever the debug option is selected from the main menu. Outputs three sections: reflectance sensor bar graph with centroid, battery voltage (corrected for the 4.7 kΩ / 10 kΩ voltage divider), and ultrasonic distance.

ui.ui_debug.run(ui)[source]

Print one debug snapshot to the serial terminal.

Reads current values from the reflectance sensor array, the battery ADC, and the ultrasonic distance sensor, then formats and writes them to the serial port. A single yield at the end makes this a generator so it integrates cleanly with the cooperative scheduler in task_user.

Args:
ui: UI context object exposing:

  • _ser: serial port for output.

  • _reflectanceSensor: sensor object whose get_values() returns (raw, calibrated, centroid, line_detected).

  • _ultrasonicDistance: share/queue whose get() returns distance in cm.

Yields:

None: Once, after all output has been written.
