NBC/NXC compiler for the Raspberry Pi (Lego Mindstorms NXT)

HOW-TO GET THE NBC/NXC COMPILER ON THE RASPBERRY PI
===================================================

I assume you are using Raspbian.


$ cd ~/path/where/i/want/to/install/nbc



Folder to hold the sourcecode:

$ mkdir nbc_src

$ cd nbc_src



Download the source code:

$ wget http://freefr.dl.sourceforge.net/project/bricxcc/NBC_NXC/NBC%20release%201.2.1%20r4/nbc-1.2.1.r4.src.tgz

If that don't work, download the nbc source code from this site:
http://sourceforge.net/projects/bricxcc/files/NBC_NXC/NBC%20release%201.2.1%20r4/nbc-1.2.1.r4.src.tgz/download

Make sure you are downloading the latest version of NBC. See all versions here:
http://sourceforge.net/projects/bricxcc/files/NBC_NXC/



Extract in current directory, make sure filename is correct

$ tar xvzf nbc-1.2.1.r4.src.tgz



Go to the newly created "NXT" directory

$ cd NXT



Now you need to install the FreePascal compiler and USB support, for transferring programs to the NXT

$ sudo apt-get install fp-compiler fp-units-fcl libusb-dev



Start compiling/assembling

$ make -f nbcunix.mak



Copy the executable from the source folder to the parent, and leave the source folder.

$ cp nbc ../../nbc

$ cd ../../

If you want you can delete the source folder:

$ rm -rf nbc_src



You can try to see of NBC is working by typing

$ ./nbc -help

You should see the help about the tool







Now let's fix USB support, so you can upload the programs to the NXT directly
I like using nano, but you can use leafpad or any other text editor

$ sudo nano /etc/udev/rules.d/71-lego.rules

Paste the following in that file:



# USB - Lego Mindstorms NXT
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="0694", ATTR{idProduct}=="0002", MODE:="0666"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="03eb", ATTR{idProduct}=="6124", MODE:="0666"




Press Ctrl+X, write Y (for english) and hit enter. The file is now saved.

Now run this command to reload the udev rules:

$ sudo udevadm control --reload-rules




You can now connect the NXT and start write programs!!



Example program:


task main() {
        ClearScreen();
        TextOut(0, LCD_LINE4, "Hello, Raspberry");

        while(1) {}
}




To compile a program and run it:

$ ./nbc myProgram.nxc -r



Enjoy!
