Fresh install of Raspian

21 Mar 2015

This is the procedure I follow to install a fresh raspbian system on a Raspberry Pi.

Preliminaries

sudo raspi-config # configure pi with text menu

sudo apt-get update # update database

sudo apt-get upgrade # update userspace

sudo rpi-update # update firmware (requires reboot)

Apple-File-Protocol (afp)

sudo apt-get install netatalk

Unison file synchronization

See my post here

sudo apt-get install unison
# see link to set up auto authentication with rsa keys
unison # run once to make /home/pi/.unison
pico /home/pi/.unison/sites.prf    

# This is contents of /home/pi/.unison/sites.prf
# Unison preferences file
root = /home/pi/Sites
root = ssh://robertcu@robertcudmore.org/raspberry/Sites

ignore = Name *.tif
ignore = Name .AppleDouble
ignore = Name .DS_Store
ignore = Name *.DS_Store
ignore = Name *.shtml
ignore = Name *.htaccess

# Be fast even on Windows
# fastcheck = yes

servercmd=/home1/robertcu/unison

Startup mailer

See my post here.

Use gmail ‘cudmore.raspberry@gmail.com’ to send

 wget http://cudmore.github.io/downloads/startup_mailer.py

What is my ip

Download whatismyip.py, run it and it will tell you your ip

 wget http://cudmore.github.io/downloads/whatismyip.py

mjpg-streamer

See my post here

sudo apt-get -y install libjpeg8-dev imagemagick libv4l-dev  
sudo ln -s /usr/include/linux/videodev2.h /usr/include/linux/videodev.h  
wget http://sourceforge.net/code-snapshots/svn/m/mj/mjpg-streamer/code/mjpg-streamer-code-182.zip  
unzip mjpg-streamer-code-182.zip  
cd mjpg-streamer-code-182/mjpg-streamer  
make mjpg_streamer input_file.so input_uvc.so output_http.so  
sudo cp mjpg_streamer /usr/local/bin  
sudo cp output_http.so input_file.so input_uvc.so /usr/local/lib/  
sudo cp -R www /usr/local/www  

sudo apt-get install v4l-utils # this is to detect parameters of USB camera  

Note, make ‘input_uvc.so’ is for usb cam and ‘input_file’ is for raspberry CSI camera

If wget does not find mjpg-streamer, download it here

wget http://cudmore.github.io/downloads/mjpg-streamer-code-182.zip

See my post on open cv here

sudo apt-get install libopencv-dev python-opencv

PIL

Not sure if there is apt-get install python-pil ???

Upgrade numpy (takes a long time)

required for pandas and bokeh

sudo pip install numpy –upgrade

Install pandas

sudo apt-get install python-pandas

Install bokeh

To do, get an example running again

sudo pip install bokeh

Install python-qt4

The list of qt libraries is huge, see here

sudo apt-get install python-qt4
sudo apt-get install python-qt4-dev

!!! Stop Here !!!

Client side socket.io javascript

Client side needs socketio javascript: http://socket.io
Put this in your Flask project /static/js/
Something like /home/pi/Sites/iosserver/static/js/socket.io.min.js

wget https://cdnjs.cloudflare.com/ajax/libs/socket.io/1.3.5/socket.io.min.js
cp socket.io.min.js Sites/iosserver/static/js/

Client side jquery

documentation at: http://jquery.com/download/

wget wget http://code.jquery.com/jquery-1.11.2.min.js
cp jquery-1.11.2.min.js Sites/iosserver/static/js/

miniconda

anaconda install tutorial http://docs.continuum.io/anaconda/install.html

wget http://repo.continuum.io/miniconda/Miniconda-3.5.5-Linux-armv6l.sh bash Miniconda-3.5.5-Linux-armv6l.sh

conda update conda conda update anaconda

bokeh

bokeh quickstart: http://bokeh.pydata.org/en/latest/docs/quickstart.html make sure dependencies are installed: NumPy, Pandas, and Redis

pip install bokeh

-mjpg_streamer –input “input_uvc.so –help” pi@pi50 ~ $ mjpg_streamer –input “input_uvc.so –help” MJPG Streamer Version: svn rev: Unversioned directory ————————————————————— Help for input plugin..: UVC webcam grabber ————————————————————— The following parameters can be passed to this plugin:

 [-d | --device ].......: video device to open (your camera)
 [-r | --resolution ]...: the resolution of the video device,
						  can be one of the following strings:
						  QSIF QCIF CGA QVGA CIF VGA 
						  SVGA XGA SXGA 
						  or a custom value like the following
						  example: 640x480
 [-f | --fps ]..........: frames per second
 [-y | --yuv ]..........: enable YUYV format and disable MJPEG mode
 [-q | --quality ]......: JPEG compression quality in percent 
						  (activates YUYV format, disables MJPEG)
 [-m | --minimum_size ].: drop frames smaller then this limit, useful
						  if the webcam produces small-sized garbage frames
						  may happen under low light conditions
 [-n | --no_dynctrl ]...: do not initalize dynctrls of Linux-UVC driver
 [-l | --led ]..........: switch the LED "on", "off", let it "blink" or leave
						  it up to the driver using the value "auto"
