arducopter - Arduino-based autopilot for mulitrotor craft, from quadcopters to traditional helis The DIY Drones development team is proud to bring you the ultimate open source quadcopter and helicopter UAV! ArduCopter's autopilot is based on APM 2, the most sophisticated IMU-based open source autopilot on the market. It provides full UAV functionality, with scripted waypoints, Ground Station and more. Advanced GCS Waypoints! See the Wiki manual linked above for full details and instructions. Sample video: GPS position and altitude hold See some other ArduCopter videos here! Order ArduCopter kits and parts here or buy them ready-to-fly here. ArduCopter Platform Feature List - default ARM architecture ARM is a family of instruction set architectures for computer processors based on a reduced instruction set computing (RISC) architecture developed by British company ARM Holdings. ARM Holdings develops the instruction set and architecture for ARM-based products, but does not manufacture products. The company periodically releases updates to its cores. Current cores from ARM Holdings support a 32-bit address space and 32-bit arithmetic; the ARMv8-A architecture, announced in October 2011,[6] adds support for a 64-bit address space and 64-bit arithmetic. Instructions for ARM Holdings' cores have 32-bit-wide fixed-length instructions, but later versions of the architecture also support a variable-length instruction set that provides both 32-bit and 16-bit-wide instructions for improved code density. Some cores can also provide hardware execution of Java bytecodes. History[edit] Microprocessor-based system on a chip The ARM1 second processor for the BBC Micro Acorn RISC Machine: ARM2[edit]

Spec. : SD Memory Card Choices Hundreds of manufacturers have built thousands of memory cards and devices to SD standards. Memory cards come in a variety of storage capacities, speed classes and three different physical sizes -- SD memory card, miniSD memory card, and microSD memory card. With so many choices, it’s important to understand which SD memory card works best with your mobile phones, tablets, personal computers, video cameras, digital cameras and other electronics devices. To determine the right card to match your device, always consult the device's user manual or contact the manufacturer. If your device supports video recording, it’s important to understand your Speed Class choices. *SD, SDHC and SDXC are trademarks or registered trademarks of SD-3C in the United States, other countries or both.

News Rikomagic GTA04 News: The codename GTA04 was picked up in 2010 by Golden Delicious Computers to develop a new motherboard for our open smartphone that follows the original idea and goals. There is a new project page: , which houses the wiki specific to the GTA04 project at Golden Delicious. GTA04A4 is a new motherboard, that replaces the one inside your Neo 1973 ( GTA01 ) or Neo Freerunner ( GTA02 ). It reuses the case, the battery, the display, the antenna and speaker(s). GTA04 hardware features is here . The GTA04A4 motherboard PCB layout development is based on GTA04A3 and its start was announced at 7 October 2011 . The replacement, populated GTA04, motherboard is available at Golden Delicious . On 14th November 2011 GTA04A4 boards became available for (pre)order. History Year 2011: GTA04A3 (Early Adopter) The GTA04A3 was released and shipped 10. october 2011. The GTA04A3 milestone was announced 7. october 2011.( source ) Video: The early adopter program was available here .

With this, it will be possible to have OMAP3 JTAG debug using cheap JTAG hardware, e.g. Flyswatter. As of September 2009, OpenOCD has basic support for OMAP3 and ARM Cortex A8 on Beagle Board. Status: You need at least OpenOCD revision 2770 (using git). To be able to use OpenOCD with OMAP3 based BeagleBoard, make sure that your JTAG Dongle supports: 1.8V devices. Flyswatter dongle supports both requirements. OpenOCD build instructions describe how to build OpenOCD. Get OpenOCD code via git: > git clone openocd For Flyswatter you additionally need libftd2xx or libFTDI. If you downloaded OpenOCD git and have libftd2xx or libFTDI, build OpenOCD (assuming you extracted/built FTDI library already): > cd openocd > . When compiling the doc directory You get an error: openocd.texi:12: @include `version.texi': No such file or directory. make pdf or > . > bp

Monitor program for Arduino in Japanese [ArduinoConf][ArduinoMonitor][iArduino] Abstract You can control Arduino's pins by ArdunoMonitor and watch changes on pins. This is useful for debugging your hardware before you write a sketch. Before you begin Place iArduino folder into your libaries folder of your Arduino folder. Start ArduinoMonitor Connect Arduino and PC, then execute ArduinoMonitor. The connection is terminated by clicking ``Disconnect'' button. Changing pin modes and values Select the usage of the pins from pull down menu on the side of the pin. Converting analog value If you check ``show in voltage'', the values of analog pins are show in voltage rather than direct value. Logging It starts logging in CSV format by clicking ``Start Log'' button. Displaying a graph It shows a graph window by clicking ``Graph'' button. It stops updates of the graph by clickng ``Stop'' button. Saving and loading a configuration It saves and loads configuration in XML format by clicking ``Save'' and ``Load'' buttons. Example sketch

Cubieboard Cubieboard is a small (10x6cm), hacker friendly, extendable and very low-cost while powerful ARM board with Allwinner A10 SoC. The board helpfully reads "Cubietech" "" and has an A10 chip on it. :) Current status The cubieboard is well represented within the main sunxi developer community and has excellent support both in u-boot as well as 3.4 and mainline kernels. Images Cubietech also has a bunch of official firmwares available on their download page. HW-Pack Generating a HW pack for the cubieboard is easily done with the sunxi-bsp and well supported. Under the BSP the cubieboard is simply known as cubieboard. . Manual build specifics For building u-boot, use the "Cubieboard" target.The .fex file can be found in sunxi-boards as cubieboard.fex Everything else is the same as the manual build howto. FEL mode The FEL button triggers FEL mode. Hardware Hacking Software Hacking DEVICE UART pads There is a nice 2.54mm pin header near to the SoC. Cubieboard Community Other links

Openmoko Beagle/Panda Hybrid - Beagleboard or Pandaboard with Openmoko Display News: We have been choosen by the PandaBoard Early Adopter Program and will receive a PandaBoard (OMAP4 / ARM Cortex A9) board soon. The Openmoko Beagle/Panda Hybrid is a PCB to connect an Openmoko Freerunner display (TD028TTEC1) through some connectors with a Beagle or Panda Board. It became the basis for a new Openmoko device and can therefore also be referenced as "GTA04A1". Please go to the specific sub-projects U-Boot for OMBKernel for OMBDebian Lenny for OMB We encourage to port/configure Android, Angstrom, QtMoko, SHR, and other distributions.

Acer Iconia Tab W500 Test, prix et avis du Iconia Tab W500 Comparatif : choisir sa tablette tactile connectée Dans la jungle naissante des tablettes tactiles, Acer a jugé bon de ne pas trop différencier ses références. C'est ainsi que nous nous retrouvons aujourd'hui avec deux tablettes du constructeur taïwanais dont les noms sont Iconia Tab A500, testée et approuvée par Les (+) Numériques, et notre patient du jour, l'Iconia Tab W500. Et pourtant, cette lettre de différence implique un lourd changement, le passage d'Android à Windows 7. Acer joue donc la carte de l'OS d'ordinateur sur produit mobile. L'architecture change radicalement puisque l'Iconia Tab W500 s'équipe d'un processeur AMD C-50 cadencé à 1GHz et non d'un cœur de type ARM, d'une touche Windows pour lancer le menu démarrer, d'une capacité mémoire de 32 Go, de 2 Go de mémoire vive et de la version Premium du système d'exploitation Windows 7.
