Arduino Yun Basics

Before starting

Assure we have:

• Installed and working Arduino Ide version 1.5.6-r2.
• Configured Arduino Yun board. See Basic Arduino Yun wireless configuration.

Let's become confident with the board

arduino.local does not always revole, safely to use the ip number (192.168.240.1, for initial configuration).

To log into the yun via ssh (from mac-osx shell): ssh root@192.168.1.13

See what is already mounted:

   mount

See which distribution, kernel version, etc:

   root@Arduino:~# cat /proc/version
   Linux version 3.8.3 (federico@smilzo) (gcc version 4.6.4 20121210 (prerelease) (Linaro GCC 4.6-2012.12) ) #8 Mon Aug 19 16:22:39 CEST 2013

Install some useful packages for video and webcam:

    #---------------------------------------------------------------------
    # install the video stuff on the yun
   opkg update
   opkg install kmod-video-uvc
   opkg install kmod-video-pwc
   opkg install kmod-input-core
   opkg install libjpeg
   opkg install fswebcam
   wget http://www.custommobileapps.com.au/downloads/mjpg-streamer.ipk
   opkg install mjpg-streamer.ipk
   opkg install ffmpeg
   opkg install ffserver
   opkg install python-openssl
   #---------------------------------------------------------------------

After each installed package, to see free space on the hard disk:

   root@Arduino:~# df -h
   Filesystem                Size      Used Available Use% Mounted on
   rootfs                    7.5M      4.9M      2.6M  66% /
   /dev/root                 7.0M      7.0M         0 100% /rom
   tmpfs                    29.9M    372.0K     29.5M   1% /tmp
   tmpfs                   512.0K         0    512.0K   0% /dev
   /dev/mtdblock3            7.5M      4.9M      2.6M  66% /overlay
   overlayfs:/overlay        7.5M      4.9M      2.6M  66% /
   /dev/sda1                 7.4G    848.0K      7.4G   0% /mnt/sda1

To run a python server

   root@Arduino:~# python -m SimpleHTTPServer

see if python server is running (from the os/x),

   $ nmap 192.168.1.13
   
   Starting Nmap 6.40 ( http://nmap.org ) at 2014-04-30 13:03 CEST
   Nmap scan report for 192.168.1.13
   Host is up (0.19s latency).

   PORT     STATE SERVICE

   8000/tcp open  http-alt
   
   Nmap done: 1 IP address (1 host up) scanned in 39.77 seconds

With standard usb uvc cam

To see the stream (from the os/x): open "http://arduino.local:8080/?action=stream" in a browser after running (on the yun via ssh):

   mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 640x480" -o "output_http.so -p 8080 -w /mnt/sda1"

to shoot a photo (on the yun via ssh):

   fswebcam test.png
