###About BeagleEye is a Datamatrix scanner meant for the Beaglebone Black or similar small computer. This program acquires a frame, scans it for datamatrices. This was just a test project to see if I could get the BBB to scan for datamatrices. All future development will be done under the https://github.com/SWiT/RobotFightClub project.
###Setup Download and install the latest Debian image from http://beagleboard.org/latest-images This guide has been tested with the Debian 4GB 2015-03-01 release.
There are a few things that need to be tweaked once the image is running on a BBB.
Set a password, set the hostname (rfc_bbb#),Set the timezone, and add ll alias
passwd
nano /etc/hostname
sudo dpkg-reconfigure tzdata
echo 'alias ll="ls -la"' >> ~/.bash_aliases
sudo reboot
Grow the partition (optional)
cd /opt/scripts/tools
git pull
sudo ./grow_partition.sh
sudo reboot
Update and install prerequisites.
sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get -y dist-upgrade
