| - | |||
| - | <code> | ||
| - | Webserver | ||
| - | |||
| - | To host the interface (which is simply a webpage), i needed an Apache webserver to be running on the Raspberry. Since this is one of the most common uses of the Rasberry, the installation of Apache is very streamlined. | ||
| - | |||
| - | First I made sure i was running the latest system software by running the following command: | ||
| - | |||
| - | sudo apt-get update && apt-get upgrade -y | ||
| - | |||
| - | |||
| - | |||
| - | sudo apt-get update | ||
| - | |||
| - | sudo apt-get upgrade -y | ||
| - | |||
| - | sudo apt-get dist-upgrade -y | ||
| - | |||
| - | sudo rpi-update | ||
| - | |||
| - | |||
| - | No it’s time to actually install apache: | ||
| - | |||
| - | sudo apt-get install apache2 apache2-doc apache2-utils | ||
| - | Done! That’s all there is. But to make sure I was able to use some PHP scripts on the webserver (more about that later), I also added PHP support: | ||
| - | |||
| - | sudo apt-get install libapache2-mod-php5 php5 php-pear php5-xcache | ||
| - | Done … again! Reboot, and the webserver is up and running! I dropped a index.php file in the /var/www folder, and pointed my browser to the Raspberry’s ip adress and yes, it worked. | ||
| - | |||
| - | Kioskmode | ||
| - | |||
| - | Now, to make sure the Raspberry actually shows the webpage I will be using Chromium in kioskmode. Chromium is an open source browser which is able to run on the Raspberry’s OS. | ||
| - | |||
| - | Once again, installing was easy: | ||
| - | |||
| - | sudo apt-get install chromium x11-xserver-utils unclutter | ||
| - | |||
| - | But this time, it needed some extra configuration to disable the | ||
| - | screensaver and autoboot in kioskmode. To do this i | ||
| - | edited /etc/xdg/lxsession/LXDE/autostart and added a # before: | ||
| - | |||
| - | /etc/xdg/lxsession/LXDE-pi | ||
| - | |||
| - | @xscreensaver -no-splash | ||
| - | Additionally, I added the following lines: | ||
| - | |||
| - | @xset s off | ||
| - | @xset -dpms | ||
| - | @xset s noblank | ||
| - | @chromium --kiosk --incognito http://localhost | ||
| - | This completely disables all screensaving features, and makes sure chromium will start after boot an points to the localhost webserver in full screen mode. | ||
| - | |||
| - | Time to save the file and reboot once more to check if it works. Since the Raspberry isn’t worlds fastest computer, it took a while, but eventually the testsite appeared on the 90 degrees rotated screen … Yeah! | ||
| - | |||
| - | On to the last part of the project. The development of the interface. | ||
| - | |||
| - | </code> | ||

| - | # enable raspicam | ||
| - | start_x=1 | ||
| - | gpu_mem=256 | ||

| - | sudo apt-get install php5-sqlite | ||

| - | |||
| - | |||
| - | <code> | ||
| - | Install avahi with the following commands on the Pi: | ||
| - | |||
| - | sudo apt-get install avahi-daemon | ||
| - | |||
| - | and then on older Debian installs: | ||
| - | |||
| - | sudo update-rc.d avahi-daemon defaults | ||
| - | |||
| - | or on newer Raspbian installs: | ||
| - | |||
| - | sudo insserv avahi-daemon | ||
| - | |||
| - | (if in doubt, you're probably on the newer one). | ||
| - | Create a configfile for Avahi at /etc/avahi/services/multiple.service. I did this with the following command: | ||
| - | |||
| - | sudo pico /etc/avahi/services/multiple.service | ||
| - | |||
| - | The contents of this file should be something like the following, courtesy of aXon on the Rasperry Pi forums: | ||
| - | |||
| - | <?xml version="1.0" standalone='no'?> | ||
| - | <!DOCTYPE service-group SYSTEM "avahi-service.dtd"> | ||
| - | <service-group> | ||

| - | <type>_ssh._tcp</type> | ||
| - | <port>22</port> | ||
| - | </service> | ||
| - | </service-group> | ||
| - | |||
| - | Apply the new configuration with: | ||
| - | |||
| - | sudo /etc/init.d/avahi-daemon restart | ||
| - | |||
| - | The Pi should now be addressable from other machines as raspberrypi.local, for example: | ||
| - | |||
| - | ssh pi@raspberrypi.local | ||

| - | With Ubuntu 14.10 and Gstreamer I reach 100 to 116 ms latency with 1280 x 720 @ 60Hz. Tanks to @Antonvh who puts me on the right way. I reproduce here the solution for latter reference.

| - | Installing Flash Player | ||
| - | The usual flashplugin-nonfree for Linux is not available for ARM devices. The solution is to use PepperFlash plugin. It's not available for the public from the Google team, but thanks to Lee Harris we can download it from his site. It's a link for the plugin for ARMv7 ripped from original Google OS from Chromebook. If you don't trust the link above you may try to rip it out yourself. After you download the archive you should extract the Pepperflash dir to /usr/lib. After that you need to do the following changes to the Chromium config file /etc/chromium-browser/default. You should modify it, so it has a line: | ||
| - | CHROMIUM_FLAGS="--ppapi-flash-path=/usr/lib/PepperFlash/libpepflashplayer.so --ppapi-flash-version=12.0.0.77" | ||
| - | Running Chromium with root rights | ||
| - | The Chromium browser doesn't launch as a root. You can change that behavior by editing it's config file /etc/chromium-browser/default. You should modify it, so it has a line: | ||
| - | CHROMIUM_FLAGS="-password-store=detect -user-data-dir" | ||
| - | If you need flash support, the line should look like this: | ||
| - | CHROMIUM_FLAGS="--ppapi-flash-path=/usr/lib/PepperFlash/libpepflashplayer.so --ppapi-flash-version=12.0.0.77 -password-store=detect -user-data-dir" | ||
| - | |||
| - | |||
| - | wget http://odroidxu.leeharris.me.uk/PepperFlash-12.0.0.77-armv7h.tar.gz | ||
| - | tar -xzf PepperFlash-12.0.0.77-armv7h.tar.gz | ||
| - | cd PepperFlash | ||
| - | chmod +x * | ||
| - | sudo cp * /usr/lib/chromium/plugins | ||
| - | sudo nano /etc/chromium/default | ||
| - | | ||
| - | Open Chromium | ||
| - | enter | ||
| - | chrome://plugins | ||
| - | |||
| - | The pepperflash-plugin should be visible. Enable it. | ||
| - | Done. | ||
