Raspberry Pi Kernel Compilation The Raspberry Pi cannot run a vanilla Linux kernel. A patched version of the kernel is maintained by the Raspberry Pi Foundation and is available from their github Prerequisites To compile a kernel, you require dev-vcs/git to download the source code and genkernel to manage the build process. root # emerge --ask git genkernel Get the Kernel Source root # cd /opt root # git clone --depth 1 # ln -s /opt/linux /usr/src/linux Compile and Install the Kernel Note Compiling will take about 6 hours. Using genkernel you can build a linux kernel with support for many different features. Default Kernel In this example the configuration options from the running kernel are used to compile the new kernel. root # genkernel --kernel-config=/proc/config.gz kernel After the kernel has compiled it will be installed into the /boot folder. Kernel with initramfs root # genkernel --kernname=rpi --menuconfig all [Collapse] Kernel configuration
130 idées pour votre Raspberry Pi Nous sommes nombreux à nous être procuré un petit ordinateur Raspberry Pi pour nous lancer dans des projets de ouf malade… C’est très cool, mais à part le classique Media Center, qu’avez-vous fait avec votre Raspberry Pi ? Où acheter un Raspberry Pi et ses accessoires ? Avant il faut savoir qu’il existe différents modèles de Raspberry Pi, comme le modèle 4 autour de 40 euros mais également le clavier Raspberry Pi 400. Ces Raspberry Pi peuvent être vendus seuls mais je vous conseille de les acheter en pack, c’est à dire avec une alimentation dédiée, un ventilateur, un boîtier…etc. Si vous séchez niveau idées, voici une petite sélection que j’ai rassemblée au cours des derniers mois. En attendant, j’espère que ceux-ci vous donneront de l’inspiration… Les projets à réaliser avec un Raspberry Pi On peut donc en faire : Et si vous cherchez un moyen rapide et pas cher de faire un boitier de protection pour vos Raspberry Pi, pensez aux LEGO. Amusez-vous bien !
6 Android Apps Every Raspberry Pi Owner Should Use Ever found yourself plugging a keyboard into your Raspberry Pi because you could be bothered to boot your PC to SSH, or found yourself desperately trying to remember the tiny computer’s IP address on your network? There are a whole host of Android utilities that can be used by Raspberry Pi owners to make life easier, including a couple that are custom designed. We’ve collected six of them together, all of which are free to install to Android phones and tablets. AndFTP It’s not often necessary to move files to your Raspberry Pi, but if this is something you require, AndFTP is a free app with a paid upgrade supporting FTP, FTPS, SCP, and SFTP. Best of all, AndFTP isn’t limited to file transfer with your Raspberry Pi — you can use it to FTP to any supported device, whether that is your Pi or a web server. Of course, if your Pi is your web server, then AndFTP should definitely be installed on your Android device! RPiREF Fing ConnectBot Hacker’s Keyboard AndroidVNC What Do You Use? Let us know below!
RPi Easy SD Card Setup Back to the Hub Getting Started: Buying Guide - for advice on buying the Raspberry Pi. SD Card Setup - for information on how to prepare the SD Card used to boot your Raspberry Pi. Basic Setup - for help with buying / selecting other hardware and setting it up. Beginners Guide - you are up and running, now what can you do? Advanced Setup - for more extensive information on setting up. Trouble Shooting - some things to check if things don't work as expected. The Raspberry Pi will not start without a properly formatted SD Card, containing the bootloader and a suitable operating system. You will also need to choose a distribution. Some Raspberry Pi kits will come with a ready-to-go card with the distribution pre-installed, or these can be bought separately. If you don't have a pre-installed card you will need to prepare your own. Buying a preloaded SD card from a reputable supplier means that you can just plug it in and power up your Raspberry Pi; it should then just work. Using NOOBS Using Etcher

Copier une puce RFID avec cet émulateur. Le montage RFIDemulator, créé par l’allemand Alexander Guthman, permet de simuler n’importe quelle puce RFID à 125 kHz compatible EM4001. Ce montage électronique est fort intéressant car c’est un gadget permettant de cloner la moindre puce RFID comme par exemple celle contenu dans votre badge pour pointer au travail. Au niveau de la conception, pas un composant compliqué, on retrouve principalement un MAX232 avec sa batterie de condensateurs pour la liaison série et un micro-contrôleur Atmel ATmega8 gère l’ensemble. On peut d’ailleurs voir sur le schéma suivant la simplicité du montage. Avant toute chose il faut capturer l’ID 64 bits d’une puce puce RFID compatible EM4001 à l’aide d’un lecteur RFID. Un programme (disponible sur le site de l’auteur) permet alors d’envoyer ce code via une liaison série RS232 à l’émulateur, qui va alors transmettre via la bobine de cuivre ce code ID 64 bits codé en Manchester. Vous pouvez retrouver l’ensemble du projet sur le site : alexanderguthmann.de

Raspberry Pi, Python & Arduino After the other night’s wonderfully slow detour into Processing, I thought I’d try the Raspberry Pi’s “native” language of Python to control an Arduino. This worked rather well, though I don’t have a slick GUI for it yet. pyFirmata is the magic that allows an Arduino running Firmata to talk to Python. It’s fairly easy to install under Raspbian: Get the required packages:sudo apt-get install python-serial mercurialDownload the pyFirmata code:hg clone cd pyfirmata sudo python setup.py install (If this succeeds, you can delete the pyfirmata folder.) Using pyFirmata is a bit different from other Arduino applications: Here’s some code that uses the same hardware as before, but simply reports the temperature and ramps the brightness of the LED up in 10% steps. The output from this might look like: If this doesn’t work, check the output of dmesg to see if you’re using the right port. which should generate something like Send the author to the moon!
