Raspberry Pi FAQs - Frequently Asked Questions
Table of Contents: The Raspberry Pi is a credit-card-sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games. It also plays high-definition video. We want to see it being used by adults and children all over the world to learn programming and digital making. You can read more about the Raspberry Pi here. The Raspberry Pi Foundation is a charity, so you can’t buy shares in the company. You can buy a Raspberry Pi from our main distributors, Premier Farnell/Element14 and RS Components/Allied Electronics. The Model A+ costs $20, the Model B+ costs $25, the Pi 2 costs $35, the Pi 3 costs $35, and the Pi Zero costs $5, plus local taxes and shipping/handling fees. You get the Raspberry Pi board itself. The components we buy are priced in dollars, and we negotiate manufacturing in dollars. 4.

Raspberry Pi MYSQL & PHPMyAdmin Tutorial - Pi My Life Up This Raspberry Pi MYSQL & PHPMyAdmin tutorial is an extension to the webserver tutorial that I did earlier. You don’t need to have done that tutorial to be able to complete this one. If you’re unfamiliar of MYSQL this is a great way to get learning it. MySQL is a relational database management system and allows you store & maintain data. It is one of the world’s most popular relational database system and is commonly included in most LAMP stacks. For anyone who doesn’t know PhpMyAdmin is a free tool that has been designed to allow for easy administration of MYSQL. RPiconfig 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.

Google and Raspberry Pi join forces to create Coder Over the last few years, interest in coding (especially for the web) has led to a blossoming of resources that help average people learn how to program from scratch. Google has decided to join the fun with a new tool called Coder — along with the help of the low-cost Raspberry Pi PC. With Coder, users can develop their own apps for the web and then host them on a miniature server located directly on the Raspberry Pi. The overall cost for the DIY programming project, using Google’s recommended materials, is under $50 — and all of the educational materials are free.

Raspberry Pi Foundation - About Us The Making of Pi The idea behind a tiny and affordable computer for kids came in 2006, when Eben Upton, Rob Mullins, Jack Lang and Alan Mycroft, based at the University of Cambridge’s Computer Laboratory, became concerned about the year-on-year decline in the numbers and skills levels of the A Level students applying to read Computer Science. From a situation in the 1990s where most of the kids applying were coming to interview as experienced hobbyist programmers, the landscape in the 2000s was very different; a typical applicant might only have done a little web design. Something had changed the way kids were interacting with computers. The Free Universal Construction Kit Ever wanted to connect your Legos and Tinkertoys together? Now you can — and much more. Announcing the Free Universal Construction Kit: a set of adapters for complete interoperability between 10 popular construction toys.

Raspberry Pi Zero W: The smart person's guide Since the original $35 Raspberry Pi computer launched in 2012, it has spawned a whole family of low-cost computers. The latest offering is the Raspberry Pi Zero W, a tiny $10 board that adds Wi-Fi and Bluetooth to the cheapest member of the Pi family, the Raspberry Pi Zero. You'll find everything you need to know about the Pi Zero W in this "living" article, which will be updated over time. R-Pi ConfigurationFile How to edit the boot configuration file for Raspberry Pi While booting up, the Raspberry Pi reads some configuration parameters from the SD card. These parameters are stored in a file named config.txt and located in the /boot partition at /boot/config.txt. You can edit this configuration file from a Mac, from a Linux PC, or from within the Raspberry Pi itself. Depending on the partitioning scheme of your SD card, the /boot partition may not be visible to Windows PCs. In this case, you will need use either a Mac, a Linux PC or the Raspberry Pi to edit the configuration file.

Starting with the Raspberry Pi (part 1) Introduction I always wanted to be able to control my electronics and multimedia with a simple and flexible system that could be easily installed and configured. After working with both PICs and Arduino, I have found the ultimate solution: the Raspberry Pi. Along with PICs and Arduino, Raspberry Pi has in common the low cost and the possibility to be configured as you like, but it is what distinguishes it to fascinate: the Raspberry Pi is a real computer, supporting a real operating system, with all the features to make it extremely easy and fun to work with complex electronic projects. Programming the ARM chip It seems to me that all the OP needs is a bootloader that provides GDB stubs for remote debugging over RS232 or Ethernet. S/he can then write whatever code s/he likes and get it running on the ARM with no OS. Unless the OP wants to learn how to bring the ARM up, in that case maybe writing (or porting) a bootloader would be the answer. In any case, I'm sure that there will be a variety of ported and home-grown efforts soon enough.
