# STATUS A/O 2016 02 14: tested, works

# based on https://barclaysapps.wordpress.com/2014/07/06/openalpr-install-for-rpi-and-udoo-and-tre-and-yun/ ,
# http://lukagabric.com/raspberry-pi-license-plate-recognition/, and updated for new packages.
# there are other random notes and googled pages that also informed this tutorial whihc may not be specifically referenced.
#This is not optimized for space or whatever, but does work. well, not as of 2016 01 03 but working to fix that)
# discussion is at https://groups.google.com/forum/#!topic/openalpr/-vckIsPe618: please contribute if you can, and ask questions if you # # have them
# thanks to Timis for tips and hints...

# how to read:

# this is a heading, as denoted by the:
# on a line where you see some text -> some more text
# this is the text in the original tutorial -> this is what you should type instead
# note: this is a note: don't type this.
# if you see a line like this ; or // anything after the ';' or the '//' including the ';'  or '//' is a note and should not be typed

# installed and tested on a raspberry pi 2 model B 1GB using raspbian installed via noobs on a 32 GB memory card.
# note that an 8GB card will fill before this tutorial ends, so you will need a card bigger than that.
# Not tested on a 16GB card so no idea if that will work or not.

# Alternatively you can do the whole thing without using noobs following these steps:
# tested using a mac: your mileage on other systems may vary
# insert the memory card into a reader and plug into your computer usb port
# diskutil list
# diskutil unmountDisk /dev/disk3
# sudo dd bs=1m if=/Users/malcolm/Desktop/2016-02-09-raspbian-jessie.img of=/dev/rdisk3

# then remove fronm the reader, plug the card into the raspberry pi and connect it to your laptop using a usb power cord and an ethernet cable.
# be sure to be sharing internet access on the mac for this to work

# ping raspberrypi.local
# ssh pi@<ipaddfress>
# pw: raspberry

# sudo raspi-config
# expand the memory card in the menu items
# enable camera support in the menu items
# reboot
