About
|

------
|
||||
======
|
||||
|
||||
HIDAPI is a multi-platform library which allows an application to interface
|
||||
with USB and Bluetooth HID-Class devices on Windows, Linux, FreeBSD, 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.
|
||||
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:

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.

Build Instructions
|
||||
-------------------
|
||||
To build the console test program:
|
||||
Windows:
|
||||
Build the .sln file in the windows/ directory.
|
||||
Linux:
|
||||
For the hidraw implementation, cd to the linux/ directory and run make.
|
||||
For the libusb implementation, cd to the libusb/ directory and run make.
|
||||
FreeBSD:
|
||||
cd to the libusb/ directory and run gmake.
|
||||
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 FreeBSD, install iconv and Fox as root:
|
||||
pkg_add -r gmake libiconv fox16
|
||||
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-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.PLATFORM where PLATFORM is
|
||||
the name of the platform (eg: Makefile.linux or Makefile.mac).
|
||||
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.
|
||||
On FreeBSD, run gmake 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:
|
||||
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
