Getting a Python script to run in the background (as a service) on boot

Different Linux distributions use different ways of starting and stopping services (some now use Upstart, some systemd). I am using the “Wheezy” Debian distribution on my Raspberry Pi,

How to use interrupts with Python on the Raspberry Pi and RPi.GPIO

http://raspi.tv/2013/how-to-use-interrupts-with-python-on-the-raspberry-pi-and-rpi-gpio How to use interrupts with Python on the Raspberry Pi and RPi.GPIO  Input and Output, interfacing, python programming, raspberry pi Add comments Mar172013   The latest big news in the world of Raspberry Pi Python GPIO programming is that Ben Croston has released an update for RPi.GPIO. Why is that a big deal? Because this version has interrupts. “What’s an interrupt?” I hear you say. It’s a way of waiting for something to happen without checking constantly whether or not it’s happening. Imagine that

How to use interrupts with Python on the Raspberry Pi and RPi.GPIO – part 2

http://raspi.tv/2013/how-to-use-interrupts-with-python-on-the-raspberry-pi-and-rpi-gpio-part-2 How to use interrupts with Python on the Raspberry Pi and RPi.GPIO – part 2  Input and Output, interfacing, python programming, raspberry pi Add comments Mar202013   Interrupts are an efficient way for a program to be able to respond immediately to a specific event. In the previous article I explained the basics of using interrupts in RPi.GPIO and gave an example of a simple “wait for an event” interrupt program. In this second article I will introduce “threaded callback” which opens up a lot

How to use interrupts with Python on the Raspberry Pi and RPi.GPIO – part 3

http://raspi.tv/2013/how-to-use-interrupts-with-python-on-the-raspberry-pi-and-rpi-gpio-part-3 Multiple threaded callback interrupts in Python We’ve been learning about interrupts this week because of the brand new interrupt capabilities of RPi.GPIO. We covered a simple “wait for” interrupt in part 1, threaded callback interrupt and button debouncing in part 2 and today we’re getting sophisticated with multiple threaded callbacks. “WoooooooooOOOOOOOOOOOOOOOooooooooooo”, I hear you say. Well actually, we’re not doing much that’s very different from last time, except, now there’s more of it. We’ll add another button and another threaded callback function

OMXPlayer Builds Update

http://omxplayer.sconde.net/   About OMXPlayer is a commandline OMX player for the Raspberry PI. It was developed as a testbed for the XBMC Raspberry PI implementation and is quite handy to use standalone. OMXPlayer has big dependencies that take long to compile on Raspberry Pi and usually without sucess, so I decided to make a build-bot for creating binary distributions for Raspbian (Debian with hard-float for RPi). I didn’t wrote the code, I just provide the binary packages. If you have

MY REINTRODUCTION TO DIGITAL PICTURE FRAMES

http://rberrypi.blogspot.com/2013/05/a-raspberry-pi-based-digital-picture.html MY REINTRODUCTION TO DIGITAL PICTURE FRAMES About 10 years ago I got the idea to build a digital picture frame based on an old 3Com Audrey  (anyone remember those?) that I bought off of eBay. I actually did build it, and it ran for a good while.  My memories of it are a little vague, but I recall it was clunky, slow, and it crashed a lot.  Around the same time, commercially built digital picture frames were starting to flood

HOWTO: Boot your Raspberry Pi into a fullscreen browser kiosk

http://blogs.wcode.org/2013/09/howto-boot-your-raspberry-pi-into-a-fullscreen-browser-kiosk/ HOWTO: Boot your Raspberry Pi into a fullscreen browser kiosk It seems there’s some demand for knowledge of setting up a full-screen, browser-based kiosk on the all-singing Raspberry Pi. Here at Watershed we’ve done this, to drive the screens of our digital signage system. Although we complicate matters a bit (we net-boot the pis, which requires a few extra tweaks – see our blog post on net-booting raspberry pis), we thought it’d be useful to document what we achieved: automatically running

Looping video playlist with Omxplayer on the Raspberry Pi

Looping video playlist with Omxplayer on the Raspberry Pi http://www.cenolan.com/2013/03/looping-video-playlist-omxplayer-raspberry-pi/ The Raspberry Pi comes with an awesome little video player called Omxplayer that is very capable of playing back full 1080p video perfectly when encoded correctly in H.264/AAC. One problem is the current lack of playlist support in omxplayer, so this post explains how to create a bash script that will permanently loop through and play a directory of videos.   First install omxplayer: sudo apt-get install omxplayer Now create this script named for

Looping videos seamlessly OMXPlayer

http://www.sundh.com/blog/2013/10/loop-videos-seamlessly-omxplayer/ Looping videos seamlessly OMXPlayer Ellen 16:30 on October 15, 2013 As I looked for different solutions for looping videos on the Raspberry Pi seamlessly I eventually came out with a solution that worked quited good for videos looping with sounds. Looking at the possiblities of using the existing example of hello_video/video.c to loop a video wasn’t an option as sound was not supported and syncing sound was not something I wanted to spend time on. Instead I looked to jbaiter’s OMXPlayer library pyomxplayer build in

Raspberry Pi playing a video in loop

http://www.mindemedia.no/wordpress/?p=16 Raspberry Pi playing a video in loop May 11, 2013 So there is gonna be an art exibition where i work, its mainly video art, so they will need six projectors showing one piece of video each, and they are all gonna run in loop, all day long. There are several boxes that can play video, and still be cheaper than the mini-mac, but none as cheap as the raspberry pi. So i decided to see if i could
