Openhab on raspberrypi

Marek Belisko — Thu, 31 Jan 2013 22:53:12 +0000

Openhab looks interesting for (not only geek) home automation. Despite of fact it’s written in java it have really nice bindings for different types of buses + native applications for iOS and Android + web access. Also provide nice designer where you can describe by semi language actions and everything about automation. I follow some advice on more webpages how to run it on raspberrypi and below you can find how to do.1. get armhf raspbian image from : http://www.raspberrypi.org/downloads (and install it on SD card)

2. get java from : http://jdk8.java.net/fxarmpreview
3. copy tar.gz file to board with e.g. rsync or other way
4. untar file:

sudo tar -zxvf file_name -C /opt

5. get openhab runtime: http://openhab.googlecode.com/files/openhab-runtime-1.1.0.zip

6. unzip it e.g. to /home/pi/openhab
7. add to .bashrc following lines:

export JAVA_HOME="/opt/jdk1.8.0"
export PATH=$PATH:$JAVA_HOME/bin

8. make start.sh script in openhab executable by:

chmod u+x start.sh

9. run ./start.sh (in openhab directory)

I verify working state with android phone. I can see demo screens and changing toggle buttons and so on.

Really impressed.

Airplay audio wifi streaming on pandaboard using shairport.

Marek Belisko — Wed, 25 Jul 2012 20:39:25 +0000

I saw week ago Airplay audio streaming on RapsberryPi board using shairport (https://github.com/albertz/shairport). I have pandaboard A2 so why didn’t try it also there.

Latest released 3.5 kernel works fine with pandaboard so compile my own kernel + use emdebian rootfs (how to is here).

Then just follow dependency information from here and compile shairport.

After runnig perl shairport.pl I have no audio. Problem was that outputs was disabled (enable Headset Left+Right Playback in alsamixer).

Anyways I finally get some sound. It’s bit distorted but at least something working .

There seems to be some kernel issue:

[ 4598.182617] DMA synchronization event drop occurred with device 66
[ 4598.744140] DMA synchronization event drop occurred with device 66

Will investigate later.

Cheers.

Compile 32bit kernel on 64 bit machine without chroot magic

Marek Belisko — Thu, 27 Oct 2011 19:53:23 +0000

I become in situation I have fast 8 core machine with 64 bit debian installed. How to compile 32 bit kernel debian way?

1. install following packages: ia32-libs, lib32gcc1, lib32ncurses5, libc6-i386, util-linux, lib32c-devel
2. if want fresh config just run : make i386_defconfig ARCH=i386; make allmodconfig ARCH=i386
3. export CONCURRENCY_LEVEL= number of cores + 1 (compilation will be little bit faster )
4. make-kpkg clean –cross-compile – –arch=i386; fakeroot linux32 make-kpkg –initrd –append-to-version=-version –cross-compile – –arch=i386 –revision=1.0.my_kernel kernel_image

And that’s it. So easy

It was long time I wrote some post so forgive me . It was little bit busy months. Anyway I’m still working on some opensource projects. One of them will be based on Panda board so any new findings and fixes will be reported here. Stay tuned
