HID API for Windows, Linux, and Mac OS X
HIDAPI library for Windows, Linux, FreeBSD and Mac OS X
=========================================================
About
------
======
HIDAPI is a multi-platform library which allows an application to interface
with USB and Bluetooth HID-Class devices on Windows, Linux, and Mac OS X.
On Windows, a DLL is built. On other platforms (and optionally on Windows),
the single source file can simply be dropped into a target application.
with USB and Bluetooth HID-Class devices on Windows, Linux, FreeBSD, and Mac
OS X. HIDAPI can be either built as a shared library (.so or .dll) or
can be embedded directly into a target application by adding a single source
file (per platform) and a single header.
HIDAPI has four back-ends:
* Windows (using hid.dll)
* Linux/hidraw (using the Kernel's hidraw driver)
* Linux/libusb (using libusb-1.0)
* FreeBSD (using libusb-1.0)
* Mac (using IOHidManager)
On Linux, either the hidraw or the libusb back-end can be used. There are

Linux/FreeBSD/libusb (libusb/hid-libusb.c):
This back-end uses libusb-1.0 to communicate directly to a USB device. This
back-end will of course not work with Bluetooth devices.
HIDAPI also comes with a Test GUI. The Test GUI is cross-platform and uses
Fox Toolkit (http://www.fox-toolkit.org). It will build on every platform
which HIDAPI supports. Since it relies on a 3rd party library, building it
is optional but recommended because it is so useful when debugging hardware.
What Does the API Look Like?
-----------------------------
=============================
The API provides the the most commonly used HID functions including sending
and receiving of input, output, and feature reports. The sample program,
which communicates with a heavily modified version the USB Generic HID
sample which is part of the Microchip Application Library (in folder
"Microchip Solutions\USB Device - HID - Custom Demos\Generic HID - Firmware"
when the Microchip Application Framework is installed), looks like this

If you have your own simple test programs which communicate with standard
hardware development boards (such as those from Microchip, TI, Atmel,
FreeScale and others), please consider sending me something like the above
for inclusion into the HIDAPI source. This will help others who have the
same hardware as you do.
License

HIDAPI may be used by one of three licenses as outlined in LICENSE.txt.
Download

It can be downloaded from github
=========
HIDAPI can be downloaded from github
git clone git://github.com/signal11/hidapi.git
Build Instructions
-------------------
To build the console test program:
Windows:
Build the .sln file in the windows/ directory.
Linux:
cd to the linux/ directory and run make.
Mac OS X:
cd to the mac/ directory and run make.
===================
To build the Test GUI:
The test GUI uses Fox toolkit, available from www.fox-toolkit.org.
On Debian-based systems such as Ubuntu, install Fox using the following:
sudo apt-get install libfox-1.6-dev
On Mac OSX, install Fox from ports:
sudo port install fox
On Windows, download the hidapi-externals.zip file from the main download
site and extract it just outside of hidapi, so that hidapi-externals and
hidapi are on the same level, as shown:
This section is long. Don't be put off by this. It's not long because it's
complicated to build HIDAPI; it's quite the opposite. This section is long
because of the flexibility of HIDAPI and the large number of ways in which
it can be built and used. You will likely pick a single build method.

+hidapi
+hidapi-externals
HIDAPI can be built in several different ways. If you elect to build a
shared library, you will need to build it from the HIDAPI source
distribution. If you choose instead to embed HIDAPI directly into your
application, you can skip the building and look at the provided platform
Makefiles for guidance. These platform Makefiles are located in linux/
libusb/ mac/ and windows/ and are called Makefile-manual. In addition,
Visual Studio projects are provided. Even if you're going to embed HIDAPI
into your project, it is still beneficial to build the example programs.
Then to build:
On Windows, build the .sln file in the testgui/ directory.
On Linux and Mac, run make from the testgui/ directory.
To build using the DDK (old method):
Prerequisites:
---------------
Linux:
-------
On Linux, you will need to install development packages for libudev,
libusb and optionally Fox-toolkit (for the test GUI). On
Debian/Ubuntu systems these can be installed by running:
sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev
If you downloaded the source directly from the git repository (using
git clone), you'll need Autotools:
sudo apt-get install autotools-dev
FreeBSD:
---------
On FreeBSD you will need to install GNU make, libiconv, and
optionally Fox-Toolkit (for the test GUI). This is done by running
the following:
pkg_add -r gmake libiconv fox16
If you downloaded the source directly from the git repository (using
git clone), you'll need Autotools:
pkg_add -r autotools
Mac:
-----
On Mac, you will need to install Fox-Toolkit if you wish to build
the Test GUI. There are two ways to do this, and each has a slight
complication. Which method you use depends on your use case.
If you wish to build the Test GUI just for your own testing on your
own computer, then the easiest method is to install Fox-Toolkit
using ports:
sudo port install fox
If you wish to build the TestGUI app bundle to redistribute to
others, you will need to install Fox-toolkit from source. This is
because the version of fox that gets installed using ports uses the
ports X11 libraries which are not compatible with the Apple X11
libraries. If you install Fox with ports and then try to distribute
your built app bundle, it will simply fail to run on other systems.
To install Fox-Toolkit manually, download the source package from
http://www.fox-toolkit.org, extract it, and run the following from
within the extracted source:
./configure && make && make install
Windows:
---------
On Windows, if you want to build the test GUI, you will need to get
the hidapi-externals.zip package from the download site. This
contains pre-built binaries for Fox-toolkit. Extract
hidapi-externals.zip just outside of hidapi, so that
hidapi-externals and hidapi are on the same level, as shown:
Parent_Folder
|
+hidapi
+hidapi-externals
Again, this step is not required if you do not wish to build the
test GUI.
Building HIDAPI into a shared library on Unix Platforms:
---------------------------------------------------------
On Unix-like systems such as Linux, FreeBSD, Mac, and even Windows, using
Mingw or Cygwin, the easiest way to build a standard system-installed shared
library is to use the GNU Autotools build system. If you checked out the
source from the git repository, run the following:
./bootstrap
./configure
make
make install <----- as root, or using sudo
If you downloaded a source package (ie: if you did not run git clone), you
can skip the ./bootstrap step.
./configure can take several arguments which control the build. The two most
likely to be used are:
--enable-testgui
Enable build of the Test GUI. This requires Fox toolkit to
be installed. Instructions for installing Fox-Toolkit on
each platform are in the Prerequisites section above.
--prefix=/usr
Specify where you want the output headers and libraries to
be installed. The example above will put the headers in
/usr/include and the binaries in /usr/lib. The default is to
install into /usr/local which is fine on most systems.
Building the manual way on Unix platforms:
-------------------------------------------
Manual Makefiles are provided mostly to give the user and idea what it takes
to build a program which embeds HIDAPI directly inside of it. These should
really be used as examples only. If you want to build a system-wide shared
library, use the Autotools method described above.
To build HIDAPI using the manual makefiles, change to the directory
of your platform and run make. For example, on Linux run:
cd linux/
make -f Makefile-manual
To build the Test GUI using the manual makefiles:
cd testgui/
make -f Makefile-manual
Building on Windows:
---------------------
To build the HIDAPI DLL on Windows using Visual Studio, build the .sln file
in the windows/ directory.
To build the Test GUI on windows using Visual Studio, build the .sln file in
the testgui/ directory.
To build HIDAPI using MinGW or Cygwin using Autotools, use the instructions
in the section titled "Building HIDAPI into a shared library on Unix
Platforms" above. Note that building the Test GUI with MinGW or Cygwin will
require the Windows procedure in the Prerequisites section above (ie:
hidapi-externals.zip).
To build HIDAPI using MinGW using the Manual Makefiles, see the section
"Building the manual way on Unix platforms" above.
HIDAPI can also be built using the Windows DDK (now also called the Windows
Driver Kit or WDK). This method was originally required for the HIDAPI build
but not anymore. However, some users still prefer this method. It is not as
well supported anymore but should still work. Patches are welcome if it does
not. To build using the DDK:
1. Install the Windows Driver Kit (WDK) from Microsoft.
2. From the Start menu, in the Windows Driver Kits folder, select Build
@ -146,8 +287,53 @@ To build using the DDK (old method):
by the build system which is appropriate for your environment. On
Windows XP, this directory is objfre_wxp_x86/i386.
--------------------------------
Cross Compiling
================
This section talks about cross compiling HIDAPI for Linux using autotools.
This is useful for using HIDAPI on embedded Linux targets. These
instructions assume the most raw kind of embedded Linux build, where all
prerequisites will need to be built first. This process will of course vary
based on your embedded Linux build system if you are using one, such as
OpenEmbedded or Buildroot.
For the purpose of this section, it will be assumed that the following
environment variables are exported.
$ export STAGING=$HOME/out
$ export HOST=arm-linux
STAGING and HOST can be modified to suit your setup.
Prerequisites
--------------
Note that the build of libudev is the very basic configuration.
Build Libusb. From the libusb source directory, run:
./configure --host=$HOST --prefix=$STAGING
make
make install
Build libudev. From the libudev source directory, run:
./configure --disable-gudev --disable-introspection --disable-hwdb \
--host=$HOST --prefix=$STAGING
make
make install
Building HIDAPI
----------------
Build HIDAPI:
PKG_CONFIG_DIR= \
PKG_CONFIG_LIBDIR=$STAGING/lib/pkgconfig:$STAGING/share/pkgconfig \
PKG_CONFIG_SYSROOT_DIR=$STAGING \
./configure --host=$HOST --prefix=$STAGING

# SYNOPSIS
#
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro figures out how to build C programs using POSIX threads. It
# sets the PTHREAD_LIBS output variable to the threads library and linker
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
# flags that are needed. (The user can also force certain compiler
# flags/libs to be tested by setting these environment variables.)
#
# Also sets PTHREAD_CC to any special C compiler that is needed for
# multi-threaded programs (defaults to the value of CC otherwise). (This
# is necessary on AIX to use the special cc_r compiler alias.)
#
# NOTE: You are assumed to not only compile your program with these flags,
# but also link it with them as well. e.g. you should link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
# If you are only building threads programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
# PTHREAD_CFLAGS.
#
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
# is not found. If ACTION-IF-FOUND is not specified, the default action
# will define HAVE_PTHREAD.
#
# Please let the authors know if this macro fails on any platform, or if
# you have any other suggestions or comments. This macro was based on work
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
# grateful for the helpful feedback of numerous users.

# lthread: LinuxThreads port on FreeBSD (also preferred to -pthread)
# -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
# doesn't hurt to check since this sometimes defines pthreads too;
# also defines -D_REENTRANT)
