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).

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):
