suggestion: Maintain consistent naming conventions for asset constants.

Consider renaming 'GDEQ031T10Display' to 'gdeq031t10Display' to match the existing lowerCamelCase convention and Dart guidelines.

Suggested implementation:

  static const String gdeq031t10Display =
      'assets/images/displays/GDEQ031T10_display.png';

If GDEQ031T10Display is referenced elsewhere in your codebase, update those references to use gdeq031t10Display for consistency.

suggestion: Avoid unnecessary type casting if Uc8253 already implements Driver.

The explicit cast can be removed for cleaner code and to prevent issues if the class hierarchy changes.

get controller => Uc8253();
