As the Raspberry Pi doesn't have a conventional BIOS, the various system configuration parameters that would normally be kept and set using the BIOS are now stored in a text file named "config.txt". The Raspberry Pi config.txt file is read by the GPU before the ARM core is initialized. This file is an optional file on the boot partition. It would normally be accessible as /boot/config.txt from Linux, but from Windows (or OS X) it would be seen as a file in the accessible part of the card. To edit the configuration file, see the instructions at R-Pi_ConfigurationFile. You can get your current active settings with the following commands: vcgencmd get_config <config> - lists a specific config value. The format is "property=value" where value is an integer. Note: In the newer Raspberry Pi models there is # before every line, if you want changes to have an affect then 'uncomment' meaning remove the #. Here is an example file disable_l2cache disable ARM access to GPU's L2 cache. start_x=1 #! Related:  RaspberryPiProjection

Ça va faire du bruit chez les framboise314 : comment configurer le son sur le Raspberry Pi Certains lecteurs du blog se sont manifestés pour dire qu’ils n’avaient pas de son sur leur Raspberry Pi. Richard (Tilalo) m’a envoyé ce mail : Salut François, J’ai lu sur ton blog que des utilisateurs n'(avaient pas de son. En cherchant sur les forum, j’ai trouvé ça : à Tilalo pour cette info, et pour les anglophobes, vous trouverez ci-dessous la traduction de l’article en question, ainsi que celle de qui liste les différents problèmes rencontrés sur le Raspberry Pi. Tout d’abord cet article de Jose P Pinilla et Holguer A Becerra Comment activer le son en HDMI et en Analogique sur un Raspberry Pi (Raspbian-Wheezy) Avant de lancer startx : Utilisez le SuperUser (après chaque reboot) ou utilisez sudo avant chaque commande Installez l’utilitaire de mise à jour du Firmware Mettez le Firmware à jour Dans config.txt : décommentez « hdmi_drive=2″ Ajoutez le module audio module au noyau et :

Self-Contained Projector Rig #piday #raspberrypi @Raspberry_Pi May 16, 2014 AT 4:00 pm Self-Contained Projector Rig #piday #raspberrypi @Raspberry_Pi Filmmaker and interactive video artist Tim Bartlett (who recently created the Kentile Floors Sign Illuminated project) shared with us a handy way to build an efficient video projection rig around your Raspberry Pi. Self-Contained Projector Rig: I was recently asked to provide a video projection for the Proteus Gowanus ball, and assembled my most compact, self-contained projector rig to date. Check out his step-by-step instructions and setup your own video looping Pi projection rig here! Featured Adafruit Tutorial! Adafruit’s Raspberry Pi Lesson 6. Each Friday is PiDay here at Adafruit!

Création d’un utilisateur pour le Raspberry-Pi | Blog de Hotfirenet Tout dépend de ce que vous voulez faire avec votre raspberry-pi, mais si celui-ci est visible sur le net je vous conseille fortement de créer un nouvel utilisateur et de supprimer l’utilisateur pi par défaut ou du moins de changer son mot de passe. Pour créer un nouvel utilisateur sur le raspberry-pi une commande suffit: sudo adduser nomUtilisateur En sachant que nomUtilisateur est le nom de votre utilisateur Le processus de création d’un utilisateur fait sa sauce. Jusqu’à ce qu’il vous demande un mot de passe. Alors toujours pareil, si le raspberry-pi est amené à être accessible depuis internet je vous conseille de mettre un vrai mot de passe. Avec au moins 8 caractères alphanumérique et un peu de caractères spéciaux. Ne soyez pas surpris si vous ne voyez pas le mot de passe que vous tapez. Si les mots de passe sont identiques, une nouvelle étape va vous demander plusieurs informations. Donner les droits super admin (root ou sudo ) à cet utlisateur Il suffit de rajouter après: Ceci:

Howto Raspberry Pi : OpenELEC on Raspberry Pi, get a great XBMC experience on your Raspberry Pi *** Updated April 5 2013 ***Major changes: Get a fully functional XBMC Media Center on Raspberry Pi ! The Raspberry Pi is a very cheap and interesting small computer created by the Raspberry foundation for educational purposes. Therefore, it comes with a GPU able to decode HD Video, a great community works on this device and allow us today to use it as a real XBMC Media Center. Major sources: To help you setting up Openlec on your Raspberry Pi, don't hesitate to take a look at following pages: My others XBMC related posts and guides: OpenELEC Raspberry Pi FAQ: OpenELEC WIKI for Raspberry Pi: OpenELEC Forum for Raspberry Pi: If you have any issue, this is the place to go!

bcm2835: C library for Broadcom BCM 2835 as used in Raspberry Pi This is a C library for Raspberry Pi (RPi). It provides access to GPIO and other IO functions on the Broadcom BCM 2835 chip, as used in the RaspberryPi, allowing access to the GPIO pins on the 26 pin IDE plug on the RPi board so you can control and interface with various external devices. It provides functions for reading digital inputs and setting digital outputs, using SPI and I2C, and for accessing the system timers. Pin event detection is supported by polling (interrupts are not supported). It is C++ compatible, and installs as a header file and non-shared library on any Linux-based distro (but clearly is no use except on Raspberry Pi or another board with BCM 2835). The version of the package that this documentation refers to can be downloaded from You can find the latest version at Several example programs are provided. Running as root Installation tar zxvf bcm2835-1.xx.tar.gz . make Reboot.

Self-Contained Projector Rig | Tim Bartlett I was recently asked to provide a video projection for the Proteus Gowanus ball, and assembled my most compact, self-contained projector rig to date. It involves Velcroing a Raspberry Pi computer to my homemade projector mount, which can be clamped anywhere with standard film grip gear. When plugged in, 1080p video plays in a loop. Getting the video to start and loop automatically was fairly simple, but required several stops on the internet: I used this script to loop video files in a folder. I added -r four lines from the end, as suggested in one of the comments. omxplayer -r $entry > /dev/null Then I made the script (named executable with the command:sudo chmod +x /home/pi/ To run the video loop, if you’re in the same directory, typenano . That worked, but I had to reboot the Raspberry Pi to get it to stop. ! To run the script on boot:sudo nano /etc/rc.local Before the final “exit 0” line, insert this line: /home/pi/videoplayer & Change the path accordingly.

Index of / Raspberry PI and Nagios Open Source monitoring » I-Security - news and security tutorials Nagios and Raspberry Pi You may all ask what does security have to do with Nagios? Well, it does. If you can’t know the status of your network / server, you won’t see a problem coming. Well, what about Raspberry PI? In this part of the tutorial I will start treating the subject of the Nagios installation on the Raspberry PI. As an OS, I have used a SD card preloaded with Debian “squeeze” 6 (download it from here: torrent or direct download). Once you have the SD ready attach-it to the Raspberry PI and power it up! We will be using a lot apt-get, so it’s better to refresh its repository (if you are behind a proxy use “export http_proxy= to set the proxy for apt-get). My RaspBerry PI up and running Please take into account that Debian comes with a pre-compiled Nagios (3.2) that can be installed with-out any trouble with this command: apt-get install nagios3. But I wish to have the latest version, so we will need to do a little compiling. And make: Almost there:

RPi Video Looper 2.0 I have a brand new version of the Raspberry Pi Videolooper that solves a lot of the common issues I'm emailed about. Hopefully this solves problems for a lot of you. You can download the new image here: How to set up the looper Copy this image to an SD card following these directionsIf you want to use USB, change usb=0 to usb=1 in looperconfig.txt on the SD card (It is in the boot partition which can be read by Windows and Mac).If you want to disable the looping autostart to make copying files easier, change autostart=1 to autostart=0 in looperconfig.txtIf you aren't using a USB (NTFS) put your video files in the /home/pi/videos directory with SFTP or by turning autostart off. Features Source code The source code can be found on github here. This is perfect if you are working on a museum or school exhibit.
