B4J Library HMITiles

HMITiles - an Open-Source HMI Tile Library for Industrial Dashboards and SCADA Applications

---

Overview

HMITiles is an open-source HMI (Human Machine Interface) tile library written in B4X, designed for building clean, consistent, and professional industrial user interfaces.

It provides reusable HMI components for:
- Industrial dashboards
- SCADA (Supervisory Control and Data Acquisition) front-ends
- Machine and process HMIs

The focus of this library is clarity, consistency, and disciplined HMI design-not visual effects or UI decoration.

Use in industrial or safety-critical environments is entirely at your own risk.

Core Tile Categories

• Buttons (including ON/OFF logic)
• Numeric and text readouts
• Sensor tiles
• Clocks and time displays
• Event and message viewers
• Sliders and setpoints
• Image tiles
• RGB indicators
• Layout and helper components

All tiles share a unified styling and state model.

Update v1.5.0 2026-01-09 (see Post #1)

- NEW: HMITileLabel - API SetFontAwesome large or default size, SetFontNormal.
- NEW: HMITileEventViewer - API RowHeight to override defaults for compact/normal mode.
- NEW: HMITileSeekBar - API ShowValue to hide the value.
- NEW: B4A examples (using the B4A library BleCentral.b4xlib) - BleScanner, GVH5075Scanner, RuuviTagScanner, Bricks BuWizz2, Lego HUB No.4.
- NEW: B4J examples - Get Started HMITileButton, HMITileLabel.
- UPD: HMITiles custom views public API aligned.
- UPD: All examples, HMITiles bug fixes.

Note
The BleCentral.b4xlib is a is a lightweight, generic BLE GATT manager and scanner for B4A, providing reliable BLE connections and notification handling.
Not published yet on the B4A additional libraries forum - still some work to do.

Has the BleCentral Lib been published? I couldn't find it in forum search.
