Problem

I would like to create my own application to control the Platinum and USB Iconasys Turntables.

Solution

The Platinum Iconasys Turntable SDK is available in the table below.

Operating SystemCompilerSDKNotesRelease Date
WindowsVC++ 2013IconasysTurntable.2.0.26867-win.zipAny references to DC motors refer to the USB Iconasys Turntables and any reference to stepper motors refer to the Platinum series turntables.Dec. 14, 2018
WindowsVC++ 2015IconasysTurntableSDK-VC2015.zip Any references to DC motors refer to the USB Iconasys Turntables and any reference to stepper motors refer to the Platinum series turntables.Feb. 04, 2019
Linuxgcc-7.3.0IconasysTurntableSDK-2.0.27362.zip

Starting with this version we added support for UI turntable configuration.

  • for linux operating system we don't develop any native UI support.
  • instead we use Qt framework under LGPL license
  • hence our turntable sdk is linked with Qt library
  • for building & linked your application with our turntable sdk, you need to download our Qt framework version used in turntable sdk

Steps for building your application with our turntable sdk (we added a test.cpp file as an example of how to use the turntable sdk)

    • add to the C++ compiler include directories option these paths:
      1. "include" dir from our zip package
      2. "include/ShutterStream" dir from our zip package
      3. "include" dir from Qt framework distribution
    • add to the linker library search these paths:
      1. "lib" dir from our zip package
      2. "lib" dir from Qt framework distribution

 

Now you should have your binary application. But it does not start at this point because it does not find the necessary libraries.

You can tell the app where to search for dependent libraries in two modes:

  1. using LD_LIBRARY_PATH environment, put in this environment variable the "lib"s folders from C++ linker library search from above .
    OR
  2. copying the needed libraries where your executable is located
    - the two libraries from "lib" folder from our zip package
    - these libraries from Qt framework: libQt5Core.so.5, libQt5Gui.so.5, libQt5Network.so.5, libQt5Qml.so.5, libQt5Quick.so.5

 

At this point you should be able to run the your application:

sudo IconasysTurntableTest (or you can add usb permission to standard user if sudo is not permitted)

If you receive the message "Turntable not opened", the kernel automatically loaded another driver for the FTDI usb device, so you need to unload them as follows:

  • sudo rmmod ftdi_sio
  • sudo rmmod usbserial

 

At this point you should be able to open the turntable and play with sdk functions.
