Cubietruck – Mini PC
SPRZĘT Cubietruck – mini PC Rynek komputerków jednopłytkowych opartych o procesory ARM zapoczątkowany przez Raspberry Pi rozwija się doskonale. Może nie jak grzyby po deszczu, ale systematycznie pojawiają się nowe rozwiązania: BeagleBoard, Marsboard, Cubieboard, Olinuxino itp. Różnią się one wyposażeniem, wydajnością, dostępnością dokumentacji oraz wsparciem technicznym. Ciekawie rozwija się propozycja Cubieboard. mocujących.

Fáciles porque podría doblar la longitud de este proyecto solo agradeciendo a mis padres la infinita paciencia que han tenido conmigo, el apoyo que me han dado siempre, y el esfuerzo que han hecho para que estas líneas se hagan realidad. Por todo ello y mil cosas más, gracias. Mamá, papá, lo he conseguido. Fáciles porque sin mi tutor Antonio, este proyecto tampoco sería una realidad, no solo por su propia labor de tutor, si no porque literalmente sin su ayuda no se hubiera entregado a tiempo y funcionando. Después de esto Antonio, voy a tener que dejarme ganar algún combate en kenpo como agradecimiento. Fáciles porque, sí melones os toca a vosotros, Alex, Alfonso, Manu, Sama, habéis sido mi apoyo más grande en los momentos más difíciles y oscuros, y mis mejores compañeros en los momentos de felicidad. Amigos de Kulturales, los hermanos Baños por empujarme a mejorar, Pablo por ser un ejemplo a seguir, Chou, por ser de los mejores profesores y amigos que he tenido jamás. -
EECS 452 – Project Hardware Possibilities
EECS 452 – Project Hardware Possibilities ñ This lecture is focused on programmable and non-programmable devices for potential project use. ñ Projects are not restricted to using C5515/DE2-70. What are some alternatives? ñ This is an awareness building lecture. It is not comprehensive. Other choices exist. ñ There has been an explosive growth of programmable/configurable devices. How to choose? The good news about computers is that they do what you tell them to do. The bad news is that they do what you tell them to do. — Ted Nelson If you can get your hands on the part, it’s obsolete. — anon Nothing is more difficult, and therefore more precious, than to be able to decide. — Napoleon Bonaparte EECS 452 – Fall 2014 Project Hardware Possibilities – Page 1/90 Thursday – Sept 18, 2014 Before we start . In today’s world there exist many, moderately powerful, very low cost, single board computers that one can use to self-educate. When doing DSP one very often wants/needs to generate an observe signals. The cost of the needed equipment can greatly dwarf the board cost. However, the cost of “equipment” is dropping. Consider the Digilent Analog Discovery. ñ $159 academic ñ 2-channel oscilloscope ñ 2-channel waveform generator ñ 16-channel logic analyzer ñ 16-channel digital pattern generator ñ Spectrum Analyzer ñ Network Analyzer ñ Voltmeter ñ Digital I/O ñ ≈$220 with bells and whistles From a Digilent web page. EECS 452 – Fall 2014 Project Hardware Possibilities – Page 2/90 Thursday – Sept 18, 2014 Risk and other ñ The safest choice in implementing your project is to make use of the C5515 and/or DE2-70 (or DE0-nano). -
Locks and Raspberries: a Comparative Study of Single-Board Computers for Access Control
UPTEC F 16013 Examensarbete 30 hp April 2016 Locks and raspberries: a comparative study of single-board computers for access control Andreas Romin Abstract Locks and raspberries: a comparative study of single-board computers for access control Andreas Romin Teknisk- naturvetenskaplig fakultet UTH-enheten Over the past decade, there has been a drastic development of the single-board computer market. These computers are now in a position where they can compete Besöksadress: with classic embedded hardware. Such fast improvement has led ASSA ABLOY, a Ångströmlaboratoriet Lägerhyddsvägen 1 well-known lock and security company, to see value in replacing some of their Hus 4, Plan 0 existing access control hardware with an off-the-shelf single-board computer. Therefore, a comparative study of single-board computers was performed for this Postadress: company. Some of the compared properties were price, performance (i.e. CPU, Box 536 751 21 Uppsala memory, USB, network, operating temperature and power consumption) and other relevant information such as operating systems, open/closed source hardware and Telefon: future availability. Information and testing data from nine different computers was 018 – 471 30 03 compiled and analyzed. This data was then used to determine the best-suited Telefax: candidates that could possibly replace the current access control hardware. They 018 – 471 30 00 were chosen in accordance to three different categories: performance, power consumption and open source hardware. The ODROID C1+, the Raspberry Pi A+ Hemsida: and the A20 OLinuXino Lime2 proved to be the best candidates for these three http://www.teknat.uu.se/student categories respectively. Furthermore, it was also concluded that the company behind a computer is just as important as the computer itself, where the best company in this study was determined to be Olimex. -
