OS Installation

RPi has no hard drive. It boots OS from an SD card. The steps to prepare bootable card are:

The SD card should be ready to boot. Safely Eject it from your computer and insert into RPi.

The First Boot

A configuration utility runs automaticllay on the first boot. Do the following:

Using SSH to control RPi from Windows computer



Pure Data

sudo apt-get install python-software-properties

sudo add-apt-repository "deb http://apt.puredata.info/releases `lsb_release -c | awk '{print $2}'` main"
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key 9f0fe587374bbe81
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key D63D3D09C39F5EEB
sudo apt-get update
sudo apt-get install pd-extended


This part may take an hour or two. In the RPi, execute:
  1. sudo apt-get clean
  2. sudo apt-get update
  3. sudo apt-get upgrade
  4. cd
  5. curl -O http://www.openframeworks.cc/versions/v0.8.1/of_v0.8.1_linuxarmv6l_release.tar.gz
  6. mkdir openFrameworks
  7. tar vxfz of_v0.8.1_linuxarmv6l_release.tar.gz -C openFrameworks --strip-components 1
  8. cd /home/pi/openFrameworks/scripts/linux/debian_armv6l
  9. sudo ./install_dependencies.sh
  10. sed -i 's/VC_IMAGE_TRANSFORM_T/DISPMANX_TRANSFORM_T/g' /home/pi/openFrameworks/libs/openFrameworks/app/ofAppEGLWindow.cpp
  11. make Release -C /home/pi/openFrameworks/libs/openFrameworksCompiled/project

Now OF can be used to compile your sources in RPi.

Compilation errors

1) In file included from src/Controller.h:6:0,
from src/TabMenu.cpp:2:
../../../addons/ofxIniSettings/src/ofxIniSettings.h:17:19: fatal error: conio.h: No such file or directory

This line was commented out: ofxIniSettings.h:17.
In addition. _getch() was commented out in ofxIniSettings.cpp:64

2) <glut.h> is not found.

OF applications

In order to get an OF application running on another Raspberry Pi (without OF), install missing dependencies with the folowing command (one long line):

sudo apt-get install libmpg123-dev alsa-base alsa-tools alsa-utils libupnp-dev automake cvs libavcodec-dev libavformat-dev libavutil-dev libswscale-dev libasound2-dev libxmu-dev libxxf86vm-dev g++ libgl1-mesa-dev libglu1-mesa-dev libraw1394-dev libudev-dev libdrm-dev libglew-dev libopenal-dev libsndfile-dev libfreeimage-dev libcairo2-dev libgtk2.0-dev python-lxml python-argparse libfreetype6-dev libassimp-dev portaudio19-dev libssl-dev libpulse-dev libgtk2.0-dev

or download the script: install_of_libs.sh , make it executable: chmod a+x install_of_libs.sh
and run: ./install_of_libs.sh


$ sudo easy_install-pypy pip

Auto login

Edit the file
sudo nano /etc/inittab

and comment out the tty1 line and replace it with
1:2345:respawn:/bin/login -f pi tty1 /dev/tty1 2>&1

Preventing the screen from going blank

The screen might go to sleep after some time as your Pi does not detect any activity. To prevent that, edit the rc.local file
sudo nano /etc/rc.local

Add the following line just before the exit 0 line:
sh -c 'setterm -blank 0 -powersave off -powerdown 0 < /dev/console > /dev/console 2>&1'

Save the file and exit. Reboot your Pi: sudo reboot.

Startup scripts

Starting a program on boot

In /home/pi create an executable shell script called startup.sh:
touch startup.sh
chmod a+x startup.sh

Then open .bashrc
sudo nano ~/.bashrc

and add the following line at the end of the file:

Save the file and exit.

Edit the startup.sh file to distinguish between direct login and SSH access. Open the file in text editor:
sudo nano ~/startup.sh

Replace the contents of the file with the following:
echo "Checking SSH connection...";

if [ -z "$SSH_CONNECTION" ]; then
echo "No SSH connection, launching scripts.";
# Your scripts here
echo "SSH connection, nothing to be launched.";

Force USB1.1 mode to get external sound card working

The RPi has a USB2.0 controller that apparently can cause issues with USB1.1 audio interfaces. The solution is to force the controller to use USB1.1 mode. You can do this by adding the following kernel parameter to your /boot/cmdline.txt file on your RPi:

NB: my USB keyboard doesn't work with this setting.

WiFi USB adapter

Follow the instructions:
$ uname -a
Linux victorpi 3.10.25+ ....

The version needs 8188eu-20131219.tar.gz

$ wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20131219.tar.gz
$ tar -xzf 8188eu-20131219.tar.gz
$ sudo install -p -m 644 8188eu.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
$ sudo insmod /lib/modules/$(uname -r)/kernel/drivers/net/wireless/8188eu.ko
$ sudo depmod -a

There is also a script that can do this (not tested, though): install-8188eu.tgz

From this page
Edit the file /etc/wpa_supplicant/wpa_supplicant.conf and add the network={.....} section.


Restart RPi without ethernet cable connected.

WiFi Access Point

From this page and this page
$ sudo apt-get install hostapd udhcpd

Edit the /etc/default/udhcpd with sudo and comment out the line:

Edit the configuration:
$ sudo nano /etc/udhcpd.conf

Change interface from eth0 to wlan0
Uncomment the remaining yes line
Change IP addresses to belong to 192.168.42.x

start #default:
end #default:
opt router
opt dns

Edit new file and add the following content to make open - that is not secure - access point
$ sudo nano /etc/hostapd/hostapd.conf


Edit the file /etc/default/hostapd and change the line:




Edit the /etc/network/interfaces.
Comment out these lines

#allow-hotplug wlan0
#iface wlan0 inet manual
#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

and add these

iface wlan0 inet static

Replace the /usr/sbin/hostapd with the one compiled from Realtek driver sources hostapd.zip
Make the file executable
$ sudo chmod a+x /usr/sbin/hostapd

Automatic service start at boot
$ sudo update-rc.d hostapd enable
$ sudo update-rc.d udhcpd enable

Start the services
$ sudo /etc/init.d/hostapd start
$ sudo /etc/init.d/udhcpd start

Restart RPi without ethernet cable connected.
