QPhidget

Phidgets are a collection of USB powered DAIO (Digital/Analog Input/Output) devices rangings from general purpose input/output to specialized modules such as motor control, motion, environment, touch and eletrical sensors. This project currently supports the basic InterfaceKit module.

Qt Phidget API

Implementation of the Phidget API exposed as QtObjects

• Event driven
• Translate Phidget events to Qt Signal and Slots mechanism
• QML compatible property bindings
• Unit tests including a mock implemenation of the Phidget21 API

Usage

From C++

// Create the phidget object
QP888Device *interfaceKit = new QP888Device();
// Connect to one or more signal
QObject::connect(interfaceKit->inputs().at(0), SIGNAL(stateChanged(bool)), this, SLOT(onInput0StateChanged(bool)));
// After opening and once the phidget is connected, signals will begin firing on changes
interfaceKit->open();

From QML

import com.soapbubble.qphidget 1.0

Rectangle {
  width: 360
  height: 360
  MouseArea {
      anchors.fill: parent
      onClicked: {
          ifk.output0 = !ifk.output0;
      }
  }
  
  IFK888 { // QML Item for InterfaceKit 8/8/8
    id: ifk
    onInput0Changed: {
        console.log('Input0: ' + state)
    }
  }
}

Building

Build has only been tested on Win32 but should be able to compile cross-platform with some additional tweaks to pro files

Requires phidget21 library installed. See http://www.phidgets.com/docs/Programming_Resources for links to download the library.

Build qphidget-lib, then qphidget-qml then qphidget (the root example app)
