HID

A Go package to access Human Interface Devices. The platform specific parts of this package are heavily based on Signal 11's HIDAPI.

Supported operating systems

The following operating systems are supported targets (as used by $GOOS environment variable)

• darwin (uses native IOKit framework)
• linux (uses hidraw)
• windows (uses native Windows HID library)

Known quirks for building on Windows 64-bit

For building this HID package, you need to have a gcc.exe in your %PATH% environment variable. There are two tested GCC toolchains: tdm-gcc and mingw-w64. At the moment (March 2015), both toolchains are missing some declarations in header files, which will result in the following error message, when running the go build:

D:\projects.go\src\github.com\boombuler\hid> go build -v -work
WORK=C:\Users\xxx\AppData\Local\Temp\go-build011586055
github.com/boombuler/hid
# github.com/boombuler/hid
could not determine kind of name for C.HidD_FreePreparsedData
could not determine kind of name for C.HidD_GetPreparsedData

The solutions is simple: just add these four lines to your gcc toolchain header file hidsdi.h

/* http://msdn.microsoft.com/en-us/library/windows/hardware/ff538893(v=vs.85).aspx */
HIDAPI BOOLEAN NTAPI HidD_FreePreparsedData(PHIDP_PREPARSED_DATA PreparsedData);

/* http://msdn.microsoft.com/en-us/library/windows/hardware/ff539679(v=vs.85).aspx */
HIDAPI BOOLEAN NTAPI HidD_GetPreparsedData(HANDLE HidDeviceObject, PHIDP_PREPARSED_DATA *PreparsedData);

Depending on your gcc toolchain installation folder, the files are located in

C:\TDM-GCC-64\x86_64-w64-mingw32\include\hidsdi.h

or

c:\mingw-w64\x86_64-4.9.2-win32-seh-rt_v3-rev1\mingw64\x86_64-w64-mingw32\include\hidsdi.h

After patching the header file, this package will compile. Future releases of the gcc toolchains will surely fix this issue.
