B4J Library HMITiles

HMITiles - an Open-Source HMI Tile Library for Industrial Dashboards

---

Overview
HMITiles is an open-source HMI (Human Machine Interface) tile library written in B4X, following widely accepted industrial HMI principles.

It provides reusable, professional-grade HMI tiles 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.

---

Design Goals

• Based on widely accepted industrial HMI principles
• Alarm-first color discipline
• Clear and consistent state handling
• Touch-friendly layouts
• No animations or visual noise
• Minimal configuration required

Implemented tiles

• 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 an unified styling and state model.

Files
HMITiles-NNN.zip archive contains the library and sample projects.

---

Install
From the zip archive, copy the file HMITiles.b4xlib to the B4J additional libraries folder.

---

Examples

• B4J-Overview - All HMI tiles at a glance. The slider changes selected tiles.
• B4A-Overview - Selected HMI tiles at a glance. The slider changes selected tiles.
• B4J-WaterTankSimulator - Simulate live data with HMI setpoint & trend tiles.
• B4J-ArduinoLED - Control onboard Arduino LED via serial line (sending/receiving single byte), Arduino firmware B4R.
• B4A-ESP32BLEED - Control ESP32 connected LED via BLE (UART), ESP32 firmware B4R.
• HomeKit32 - Real example controlling the HomeKit32.

Basic Example

HMITiles are standard B4X CustomViews and can be placed in the Designer.
Example: simple ON / OFF HMITile

Sub Class_Globals
    Private HMITileButtonOnOff As HMITileButton
    ...

Private Sub B4XPage_Created (Root1 As B4XView)
    ...
    ' OnOff Button
    HMITileButtonOnOff.State = False
    ...

Private Sub HMITileButtonOnOff_Click
    HMITileButtonOnOff.SetState(HMITileButtonOnOff.State)
    HMITileButtonOnOff.StateText = IIf(HMITileButtonOnOff.State, "ON", "OFF")
    Log($"[HMITileButtonOnOff] state=${HMITileButtonOnOff.State}"$)
End Sub

---

To-Do

• Additional HMITiles: HMITileStateIndicator, HMITileFormHeader, HMITileMenuButton.
• FarmKit32 - Control the FarmKit32. Similar to HomeKit32 but then using the Keyestudio Smart Farm Kit KS0567 (docs.keyestudio.com/projects/KS0567/en/latest/wiki/index.html).
