Connecting Peripheral Devices to a Pandaboard Using
11/16/2012 MARK CONNECTING PERIPHERAL DEVICES TO A BIRDSALL PANDABOARD USING PSI This is an application note that will help somebody use the Serial Programming Interface that is available on the OMAP-based PandaBoard’s expansion connector and also explains how use the SPI to connect with a real-time clock (RTC) chip. Ever since the PandaBoard came out, there has been a community of eager programmers constructing creative projects and asking questions about where else and what more they could do to extend the PandaBoard’s abilities. This application note will document a way to connect devices to a OMAP-based devise like a PandaBoard What is the Serial Programming Interface “Serial Programming Interface” (SPI) is a simple standard that was developed my Motorola. SPI can also be called “4-wire” interface (as opposed to 1, 2 or 3-wire serial buses) and it is sometimes referred to like that because the interface has four wires defined. The first is Master- Out-Slave-In (MOSI) and the second is the Master-In-Slave-Out (MISO). There is also a Serial Clock from the Master (SCLK) and a Chipselect Signal (CS#) which can allow for more than one slave devise to be able to connect with one master. Why do we want to use the SPI? There are various ways to connect a peripheral device to the PandaBoard like USB, SPI, etc... and SPI has some advantages. Using the Serial Programming Interface costs less in terms of power usage and it is easy to connect different devises to the PandaBoard and also to debug any problems that occur all while maintaining an acceptable performance rate. -

Improving the Beaglebone Board with Embedded Ubuntu, Enhanced GPMC Driver and Python for Communication and Graphical Prototypes
Final Master Thesis Improving the BeagleBone board with embedded Ubuntu, enhanced GPMC driver and Python for communication and graphical prototypes By RUBÉN GONZÁLEZ MUÑOZ Directed by MANUEL M. DOMINGUEZ PUMAR FINAL MASTER THESIS 30 ECTS, JULY 2015, ELECTRICAL AND ELECTRONICS ENGINEERING Abstract Abstract BeagleBone is a low price, small size Linux embedded microcomputer with a full set of I/O pins and processing power for real-time applications, also expandable with cape pluggable boards. The current work has been focused on improving the performance of this board. In this case, the BeagleBone comes with a pre-installed Angstrom OS and with a cape board using a particular software “overlay” and applications. Due to a lack of support, this pre-installed OS has been replaced by Ubuntu. As a consequence, the cape software and applications need to be adapted. Another necessity that emerges from the stated changes is to improve the communications through a GPMC interface. The depicted driver has been built for the new system as well as synchronous variants, also developed and tested. Finally, a set of applications in Python using the cape functionalities has been developed. Some extra graphical features have been included as example.

Low-Power High Performance Computing
Low-Power High Performance Computing Michael Holliday August 22, 2012 MSc in High Performance Computing The University of Edinburgh Year of Presentation: 2012 Abstract There are immense challenges in building an exascale machine with the biggest issue that of power. The designs of new HPC systems are likely to be radically different from those in use today. Making use of new architectures aimed at reducing power consumption while still delivering high performance up to and beyond a speed of one exaflop might bring about greener computing. This project will make use of systems already using low power processors including the Intel Atom and ARM A9 and compare them against the Intel Westmere Xeon Processor when scaled up to higher numbers of cores.

INSTALL ARCH LINUX ARM for a SIMPLE LAN SERVER the Hardware
INSTALL ARCH LINUX ARM FOR A SIMPLE LAN SERVER The Hardware At the top, two possibilities for the DATA drive which will store all your files. A USB-3 SSD external housing with a SSD of your choice and size. In this case a Samsung 850 500GB SSD. OR if more storage is needed, a USB-3 3.5 inch external hard drive enclosure, in this case with a 2 TB WD Red Label hard drive. Next is a 5 VDC 6 Amp power brick for the Odroid-XU4, not shown is a 12 VDC power supply included with the 3.5 inch hard drive if used. At the bottom, a USB SD Reader. A micro SD to SD adapter. A micro SD card OR an emmc to micro SD adapter with an emmc card for the Operating System. Then the Odroid- XU4 SBC (Single Board Computer). With optional Real Time Clock battery, 40 mm cooling fan, and a 1/4 inch plywood base with stand offs to protect the components on the bottom. Of course, any ARM device that Arch Linux Arm supports can be used, such as a Raspberry PI 4 or the new Odroid N2 with 4 GB RAM, or what ever. Just go to the Arch Linux Arm site, https://archlinuxarm.org/ Hover over "Platforms" then the Architecture, brand name, etc. to see if your device is supported. Click on your device and get a page with overview and installation tabs.

Smart Walker IV
Multidisciplinary Senior Design Conference Kate Gleason College of Engineering Rochester Institute of Technology Rochester, New York 14623 P16041: Smart Walker IV Alex Synesael Alexei Rigaud Electrical Engineering Electrical Engineering Danielle Stone Stephen Hayes Electrical Engineering Electrical Engineering ABSTRACT Diagnostic medical technology in its current form is typically expensive and intrusive to a patient’s lifestyle. The purpose of the Smart Walker IV project was to finalize a robotic assistive walker prototype capable of collecting long-term diagnostic information about a patient’s health and activities. This gives care providers a more complete image of their health than can be achieved during a relatively short visit. In addition to the diagnostic features, Smart Walker is capable of autonomous motion such that it can provide emergency support in the event of a fall, or contact the appropriate third party support. Smart Walker IV is a culmination of three previous prototype versions spanning 2013 through 2015, and is intended to serve as the final revision before the platform is ready to be utilized as a graduate research platform for robotic assistive medical diagnostics. The goal of Smart Walker IV is to complete the build and integration phases from where the previous Smart Walker III team ended. The project progressed through analysis and completion of the existing systems, the design and testing of new diagnostic subsystems, and finally complete system integration and qualification. BACKGROUND Smart Walker began as a diagnostic tool for elderly people, and has since evolved into a research platform. The Smart Walker can take diagnostic measurements, as well as measure vital signs and detect when a patient has fallen. -
Iot Configuration for Industrial and Domestic Water Saving Monitoring
ARISTOTLE UNIVERSITY OF THESSALONÍKI COMPUTER SCIENCE DEPARTMENT IoT Configuration for Industrial and Domestic Water Saving Monitoring Iraklis Moutidis Advisor: Ioannis Stamelos 1 Abstract The main objective of the thesis is to implement a water flow monitoring system, using a water flow sensor, the Arduino prototyping board and the Raspberry Pi board. The system should be efficient regarding the electricity consumption and flexible regarding the water installation it will be placed. The information obtained from the sensor(s) is uploaded to a cloud platform (Thingspeak.com) and also locally stored on the Raspberry Pi, which is used as a server for any boards like the Arduino that control a sensor. The data can be further processed to obtain more information about the water consumption of the installation. 2 Contents 1.
