Changelog

All notable changes to HMITiles - are documented in this file.

The project follows semantic versioning where possible.

[2.0.1] - 2026-05-23

  • NEW: Example 57-GeneratorSimulator - Demo simulates a standard European 220V/230V @ 50Hz 4-pole industrial diesel generator
  • NEW: Example 58-ColdStorageSimulator - Demo simulates an environmental control chamber / industrial refrigerator loop
  • NEW: Example 59-ConveyorSortingSimulator - Demo simulates a factory material-handling conveyor belt line driven by a VFD motor
  • NEW: Example 60-LighthouseSimulator - Automation example modeling a coastal marine lighthouse station console
  • FIX: HMITileSlider - Handling value < min range or > max range; Tickmarks fixed length instead barheight/width
  • FIX: HMITileEventViewer - Property MaxEvents wrongly initialized as MaxItems (caused eventviewer crash)

[2.0.0] - 2026-05-19

  • NEW: Alarm Concept - Title changes color & indicator added depending state (normal, warning, alarm) and not the full tile anymore (clear visual hierarchy that instantly tells the status without overwhelming the screen)
  • NEW: HMITileDeviation - Bidirectional bar to indicate process value deviation from the set point
  • NEW: HMITileGauge - Properties Show Needle, Show Range Labels
  • NEW: HMITileGaugeSegments - Like HMITileGauge but with additional Warning/Alarm segments and shape indicator
  • NEW: HMITileLabelTitle - Tile with title label and centered label (with properties TextSize, TextColor)
  • NEW: HMITileUtils - Method MapRange
  • NEW: HMITileSlider - Slider control tile for interactive value adjustment
  • NEW: HMITileSymbols - Common symbol constants and helper subs for HMITileCustom
  • NEW: HMITileTrend - Applied graph smoothing (Chaikin Algorithm); Property GridColor; Event Click
  • NEW: HMITiles with Value & Unit - Added label Unit; Stacked labels Value (top) and Unit (bottom)
  • NEW: HMITilesX - Library with HMITiles extensions which go beyond the HMI design principles
  • NEW: HMITileLevel - Added level type Bar, Circle; Replaced bar & fill panes with b4xcanvas rectangles
  • UPD: HMITileSPPV - Seperator line between PV and SP; Warning/Alarm shape indicator below seperator line
  • UPD: HMITiles - Renamed mBase to BasePane (Public), mLbl to BaseLabel (Private)
  • UPD: Indicator Tiles - Consistent use of background track and active level colors
  • UPD: Examples - Folder structure using numeric index; Removed subfolders; Reworked all examples & some renamed
  • DEL: Examples - B4A & B4J Overview removed. Use B4A & B4J development app and program instead (folder src)
  • DEL: HMITileLevelIndicator - Included level type Circle in HMITileLevel
  • DEL: HMITileRGB - Moved to the new HMITilesX library
  • DEL: HMITileShape - Moved to the new HMITilesX library
