I've been trying to read data (x/y axis, pressed buttons, etc) from a usb joystick, and I've heard of DirectInput. Been searching for some long hours to find a decent example or walkthrough with little success. If anyone can share a simple tutorial, or guide me to the correct place, I'll be in your debt. Thank you

edit: Trying to achieve this goal on Windows platform

  • What operating system are you using? – Panagiotis Mar 16 '12 at 18:25
  • Sorry forgot to mention, I'm using Windows7, and hoping the program would work on most of the Windows releases – tdgtyugdyugdrugdr Mar 16 '12 at 18:27
  • [This](http://msdn.microsoft.com/en-us/library/windows/desktop/ee418631(v=vs.85).aspx) looks pretty specific to your needs. Not exactly a tutorial, but it is the official site for this stuff. – chris Mar 16 '12 at 18:30

There are a few DirectInput samples in DirectX SDK, source code and compiled binaries. Included is Joystick sample. Older versions of SDK (look for "DirectX 9.0 SDK", years around 2004-2005) had even more samples, up to a dozen!

Joystick Sample

Description The Joystick sample program obtains and displays joystick data.

Path Source: (SDK root )\Samples\C++\DirectInput\Joystick

Executable: (SDK root )\Samples\C++\DirectInput\Bin\Joystick.exe

User's Guide Observe how the displayed data changes when you move and twist the stick, rotate the throttle wheel, and press buttons in various combinations.

Programming Notes The application polls the joystick for immediate data in response to a timer set inside the dialog procedure.

I used walbourn/directx-sdk-samples on github and it works perfectly.

I had to configure .pro file as follows to run it on Qt Creator:

TEMPLATE = app
CONFIG += c++14
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp
HEADERS += resource.h
DISTFILES += directx.ico joystick.rc
RC_FILE = joystick.rc

DEFINES -= UNICODE
#DEFINES += _MBCS

win32: QMAKE_CXXFLAGS_RELEASE -= -Zc:strictStrings
win32: QMAKE_CFLAGS_RELEASE -= -Zc:strictStrings
win32: QMAKE_CXXFLAGS_DEBUG -= -Zc:strictStrings
win32: QMAKE_CFLAGS_DEBUG -= -Zc:strictStrings
win32: QMAKE_CFLAGS -= -Zc:strictStrings
win32: QMAKE_CXXFLAGS -= -Zc:strictStrings

LIBS += -L"C:/Program Files (x86)/Windows Kits/10/Lib/10.0.10240.0/um/x64"
LIBS += -lshell32 -luser32 -ldxguid -lcomctl32 -lole32 -loleaut32 -ldinput8

Probably these might help you:

  1. Directinput devices
  2. Coding4Fun joystick

actually Coding4Fun has a lot of interesting things. It began around the time Win7 were released.
