Shutdown Script for Retropie
Shutdown Script for Retropie Use pin number 5 & 14 for “Shutdown” 1. Update RetroPie: • sudo apt-get update 2. Upgrade RetroPie • sudo apt-get upgrade 3. Install Python • sudo apt-get install python-dev • sudo apt-get install python3-dev • sudo apt-get install gcc • sudo apt-get install python-pip 4. Next you need to get RPi.GPIO: • wget https://pypi.python.org/packages/source/R/RPi.GPIO/RPi.GPIO-0.5.11.tar.gz 5. Extract the packages: • sudo tar -zxvf RPi.GPIO-0.5.11.tar.gz 6. Move into the newly created directory: • cd RPi.GPIO-0.5.11 • 7. Install the module by doing: • sudo python setup.py install • sudo python3 setup.py install 8. Creating a directory to hold your scripts: • mkdir /home/pi/scripts 9. Call our script shutdown.py (it is written in python). Create and edit the script by doing: • sudo nano /home/pi/scripts/shutdown.py The content of the script: Paste it in the blank area #!/usr/bin/python import RPi.GPIO as GPIO import time import subprocess # we will use the pin numbering to match the pins on the Pi, instead of the # GPIO pin outs (makes it easier to keep track of things) GPIO.setmode(GPIO.BOARD) # use the same pin that is used for the reset button (one button to rule them all!) GPIO.setup(5, GPIO.IN, pull_up_down = GPIO.PUD_UP) oldButtonState1 = True while True: #grab the current button state buttonState1 = GPIO.input(5) # check to see if button has been pushed if buttonState1 != oldButtonState1 and buttonState1 == False: subprocess.call("shutdown -h now", shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) oldButtonState1 = buttonState1 time.sleep(.1) Press CRTL X Then Y and Enter 10. -

Table of Contents Configuring UNIX-specific settings: Creating symbolic links . 1 Creating symbolic links for the Domino plug-in on Linux and Solaris hosts. 1 Creating symbolic links for the Domino plug-in on AIX hosts. 2 Configuring UNIX-specific settings: Creating symbolic links If you are going to install the Snap Creator Agent on a UNIX operating system (AIX, Linux, and Solaris), for the IBM Domino plug-in to work properly, three symbolic links (symlinks) must be created to link to Domino’s shared object files. Installation procedures vary slightly depending on the operating system. Refer to the appropriate procedure for your operating system. Domino does not support the HP-UX operating system. Creating symbolic links for the Domino plug-in on Linux and Solaris hosts You need to perform this procedure if you want to create symbolic links for the Domino plug-in on Linux and Solaris hosts. You should not copy and paste commands directly from this document; errors (such as incorrectly transferred characters caused by line breaks and hard returns) might result. Copy and paste the commands into a text editor, verify the commands, and then enter them in the CLI console. The paths provided in the following steps refer to the 32-bit systems; 64-bit systems must create simlinks to /usr/lib64 instead of /usr/lib. -

Last modified by ipv1 on Aug 18, 2015 9:52 AM. Introduction What do you need? Step 1. Setup the RPi Step 2. Connecting the button Step 3. Writing a Python Script Step 4. Adding it to startup Step 5. More to do Introduction For a beginner to the world of raspberry pi, there are a number of projects that can become the start of something big. In this article, I discuss such a simple project which is adding a button that can be used to shutdown the raspberry pi using a bit of software tinkering. I wrote a similar article in 2013 at my blog “embeddedcode.wordpress.com” and its got its share of attention since a lot of people starting out with a single board computer, kept looking for a power button. Additionally, those who wanted a headless system, needed a way to shutdown the computer without the mess of connecting to it over the network or attaching a monitor and keyboard to it. In this article, I revisit the tutorial on how to add a shutdown button while trying to explain the workings and perhaps beginners will find it an amusing to add find more things to do with this little recipe. What do you need? Here is a basic bill of materials required for this exercise. -

Shutdown policies with power capping for large scale computing systems Anne Benoit1, Laurent Lef`evre1, Anne-C´ecileOrgerie2, and Issam Ra¨ıs1 1 Univ. Lyon, Inria, CNRS, ENS de Lyon, Univ. Claude-Bernard Lyon 1, LIP 2 CNRS, IRISA, Rennes, France Abstract Large scale distributed systems are expected to consume huge amounts of energy. To solve this issue, shutdown policies constitute an appealing approach able to dynamically adapt the resource set to the actual workload. However, multiple constraints have to be taken into account for such policies to be applied on real infrastructures, in partic- ular the time and energy cost of shutting down and waking up nodes, and power capping to avoid disruption of the system. -
Master's Thesis Electronic Gatekeeper Using ETHERNET
University of West Bohemia Faculty of Applied Sciences Department of Computer Science and Engineering Master’s thesis Electronic Gatekeeper using ETHERNET Plzeň 2019 Hamza Elghoul Místo této strany bude zadání práce. Declaration I hereby declare that this master’s thesis is completely my own work and that I used only the cited sources. Plzeň, 2 May 2018 Hamza Elghoul Abstract The aim of this thesis is the analysis and the realization of a budget 2-way communication system using ETHERNET connection, more specific- ally a door intercom station (hereinafter ”Bouncer” or "Gatekeeper"), where it is possible to make voice calls between two CLIENTS, a CALLER and a CALLEE with an acceptable to minimal delay. There are many alternative methods available for implementing such sys- tems, this project will try to compare some of these solutions and choose the most convenient platform according to a number of factors, such as band- width, processing power needed and communication protocols in question.
