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
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.
