Vi Cheat Sheet. Wiimote. This article will go through the basic steps required to have a working Wiimote in Linux for general use. It will not go into much detail for some steps as there are many guides already written for some parts already. Note: The approach shown on this page is based on software which is no longer developed upstream. There is a new effort on creating a Wii Remote driver based on the new Linux kernel Wii Remote driver. See XWiimote if you want to test the new Wii Remote software stack.
Prerequisites Bluetooth cwiid Wiimote The most important piece required is Bluetooth, this must already be configured and running without the help of this guide. Connect the Wiimote First you need to make sure to load the uinput module: $ sudo modprobe uinput You should have a device in /dev/uinput now. Thanks to cwiid you can scan for your Wiimote now: (press the 1 and 2 buttons on your Wiimote) $ hcitool scan Scanning ... Input Device The Wiimote can act as a regular input device like a mouse using wminput. 1. 2.

In the same state of mind, those algorithms are not fully optimised, they are explained for pedagogical purposes and you may find some redundant computations or other voluntary clumsiness. 1 – Simple sound energy.

Low-level Peripherals and Expansion Boards. Screens, Cases and Other Peripherals. Introduction In addition to the familiar USB, Ethernet and HDMI ports, the Raspberry Pi offers the ability to connect directly to a variety of electronic devices. Digital outputs: turn lights, motors, or other devices on or off Digital inputs: read an on or off state from a button, switch, or other sensor Communication with chips or modules using low-level protocols: SPI, I²C, or serial UART Connections are made using GPIO ("General Purpose Input/Output") pins.
Note that no analogue input or output is available. Links For further specific information about the Raspberry Pi's BCM2835 GPIOs, see: RPi BCM2835 GPIOs. Model A and B (Original) The Raspberry Pi Model A and B boards have a 26-pin 2.54 mm (100 mil)[1] expansion header, marked as P1, arranged in a 2x13 strip. Revision 1 PCBs also do not have the P5 header (see below). Useful P2 pins: How-To: GPIO on Raspberry Pi. Raspberry Pi | Wiring | Pins. Update: 14th May, 2013 wiringPi version 2 has been released and now has its own website ( to look after it. Most of the documentation on the projects site has been copied over to it the new site, but there may still be 1 or 2 pages that are still missing.
I’d encourage you to use the new site if possible where there will be a forum and wiki. The following tables give the mapping of the Raspberry Pi GPIO Pins to the GPIO connector in relation to the pin numbers and the physical location on the connector. This is a representation of the GPIO connector as viewed looking at the board from above, with the USB power at the top and the GPIO to the top-right of the board. If using the connector pin numbering, then note that Pin 1 on the connector is the 3.3v supply. Pin 2 is the 5V supply, and pin 26 is marked SPI CE1 below. P1: The Main GPIO connector: Board Revisions: Please note the differences between board revisions 1 and 2 (R1 and R2 above) Each side has three columns. GPIO. Raspberry Pi | Wiring. Update: 14th May, 2013 wiringPi version 2 has been released and now has its own website ( to look after it.
Most of the documentation on the projects site has been copied over to it the new site, but there may still be 1 or 2 pages that are still missing. I’d encourage you to use the new site if possible where there will be a forum and wiki (when I get time to implement them!) WiringPi is an Arduino wiring-like library written in C and released under the GNU LGPLv3 license which is usable from C and C++ and many other languages with suitable wrappers (See below) You may be familiar with the Arduino… Briefly; Arduino is really two things; one is a hardware platform, the other software, and part of the software is a package called Wiring.
Wiring is the core of the input and output for the Arduino, so I thought it would be good to replicate that functionality (or a good usable subset) on the Raspberry Pi. WiringPi Resources Additional Libraries The PiFace board:
