View source for CSC231 Customizing Ubuntu LiveCD to connect to Arduino stamp

====Process====

The process is fairly simple:

# get the '''ISO''' of the current Ubuntu liveCD [https://help.ubuntu.com/community/LiveCD]
# Follow the '''directions''' from the very nice customization page [https://help.ubuntu.com/community/LiveCDCustomization here]
## '''Boot''' with the liveCD
## '''copy''' the liveCD to a new directory on a hard disk with enough free space (~ 5-10 GB)
## '''unpack''' liveCD
## '''chroot''' to the unpacked version
# add '''sun-java5-jre''' (this takes a lot of steps using dpkg -f install commands to update all dependencies)
# add the '''libRxTx''' library (http://mirrors.kernel.org/ubuntu/pool/universe/r/rxtx/librxtx-java_2.1.7-2_i386.deb). This is a set of drivers that allow communication over the USB port.  This is the reason a LiveCD is a good solution, because otherwise all computers already setup and locked  would have to be modified to have these drivers installed.
# get the '''Arduino''' software and copy it to a convenient location in the chrooted environment
# copy the '''SimpleMessageSystem''' software to arduino library folder
# copy '''nasm''', '''gcc''',  '''emacs22''' to chrooted environment
# come '''out of chroot'''
# create new '''ISO''' file version of liveCD
# '''reboot''' as regular Linux machine
# '''burn''' ISO version to DVD with ''k3b'' (because the new installed package make ISO larger than max size of CDRom)

Detailed notes can be found [http://docmetro.dyndns.org/wiki/index.php/Create_New_Ubuntu_Distro here]

====Testing Customization, Version 1====

# Reboot from the newly customized LiveDVD.
# Find Arduino folder in '''/root''' and start Arduino app (Ubuntu will offer serveral options: choose run from Terminal)
# Make sure '''board''' and '''connection''' are set in ''tools'' menu.
# Load examples/digital/'''blink''' sketchbook
# '''Download''' it to Arduino. 
# '''Reset''' Arduino
# LED should blink

====Testing Customization, Version  2====

# Open sketchbook library.simpleMessageSystem.example1
# Uploaded it to board
# Copy driver.c, asm_io.inc, asm_io.asm, and ledOn.asm from [[#Assembly_Program_to_turn_LED_.28Digital_Pin_13.29_ON | Assembly Program]] section above
# Compile and run the application as follows:

   nasm -f elf -d ELF_TYPE asm_io.asm
   nasm -f elf -d ELF_TYPE ledOn.asm
   gcc -o ledOn driver.c ledOn.o asm_io.o
   ./ledOn

:Led should turn on.  Feel free to create ledOff.asm to turn it off ;-)

====Using a USB drive/mem-stick ====

Instead of installing Arduino on the liveCD, one could use a USB memory stick to keep a live version of Arduino and of the sketchbook.   In this case the approach would be to 

# Create a new distro of Ubuntu as above, but skip installation of Arduino software
# Plug a USB drive in a USB port and wait until Ubuntu recognizes it
# The icon for the new drive should appear on the Ubuntu Desktop
# Install Arduino software on new USB drive (get arduino-0011-linux.tgz or current version from http://www.arduino.cc/files)
# Installed SimpleMessageSystem package in Arduino library
