Home < LEGO IGT CompilationNXT_USB is a C++ library used to control a LEGO Mindstorms NXT robot over a USB connection.
This code was modified from:
- NXT++: http://nxtpp.sourceforge.net
- Device::USB: http://search.cpan.org/~gwadej/Device-USB-0.21
Contents
Linux Installation
Reqirements
- This code can be used only on a Linux distribution with root access. Remember to run any software utilizing this code as root.
- libusb: http://libusb.sourceforge.net/
Instructions
Download libusb from:
http://libusb.sourceforge.net (version 0.1.12)
Then run:
tar zxvf libusb-0.1.12.tar.gz cd libusb-0.1.12/ ./configure CFLAGS=-funsigned-char --prefix=<your libusb directory> --exec-prefix=<your libsub directory> make make install
Then add the libusb directory to your $LD_LIBRARY_PATH variable. Note that the INSTALL.libusb file has information about the installation process.
Another alternative is to use CMake:
SET(CMAKE_CXX_FLAGS "-funsigned-char" )
INCLUDE_DIRECTORIES( ... <your libusb directory (can be a relative path)> )
ADD_LIBRARY(<your library name> ... NXT_USB.cxx NXT_USB_linux.cxx )
FIND_LIBRARY(LIBUSB_LIB NAMES libusb-lib PATHS <your libusb directory (can be a relative path)>/lib )
TARGET_LINK_LIBRARIES(Lego ... <your libusb directory (should be an absolute path)>/lib/libusb.so )
The simplest way to use this library is to keep the four NXT_USB files (NXT_USB.h, NXT_USB.cxx, NXT_USB_linux.h, and NXT_USB_linux.cxx) in the same directory as your program. Simply #include "NXT_USB.h" and compile as usual.
Windows Installation
The Windows installation of the NXT_USB requires the windows port of libusb using libusb-win32 open-source project.
- Go to SourceForge
- Install libusb-win32-filter-bin-0.1.12.1.exe by following the instructions
- Download libusb-win32-device-bin-0.1.12.1.tar.gz from SourceForge
- Extract libusb-win32-device-bin-0.1.12.1.tar.gz using winrar or cygwin (tar -zxf)
- Plug the USB cable to your computer and start the Lego NXT (it won't be recognized, just wait if you got the windows device wizrd
- Start libusb-win32-device-bin-0.1.12.1/bin/inf-wizard
- Select the device corresponding to the Lego NXT
- Enter some information: name, etc.. (this is arbitrary)
- inf-wizard will create a .cat, .ing, .PNF files
- In the same directory where the generated files have been written copy the libusb0.dll and libusb0.sys (located in the libsb-win32-device-bin)
- Using the Windows device wizard, select the .inf file generated
- Go to 'Start Menu'->'Programs'->'LibUSB-Win32'->'Test Program', you should see the NXT device:
