Objective: We want to be able to connect to the RaspberryPi with patchboxOS so we can connect to it via a local Ethernet cable directly connected to the computer without any router. Steps to follow:
Prepare the system
download the patchbox os image and put it on SD card with Etcher.
- setup fallback fixed IP if no DHCP server is in the network
- Method A: connect an HDMI monitor and USB keyboard to the RaspberryPi. Go to step 5 :)
- Method B: connect Raspberry and computer to a router with DHCP.
- open the terminal type ifconfig to see the local IP address of the computer.
- type ping patchbox.local to see if the Raspberry is running and find its IP address. Tto stop the output press Ctl+Shift+C.
- type ssh -X patch@patchbox.local} to connect to the Raspberry. Default password of the user "patch" is "blokaslabs"
- Follow the setup and change the password.
- add a fallback static IP if no DHCP server is in the network: Type
sudo nano /etc/dhcpcd.conf
You are in a text editor now. Uncomment (remove the # symbol) the lines defining the fallback address like this https://wiki.archlinux.org/index.php/dhcpcd#Fallback_profile
Once that is done, you can connect to the internet and bring the OS up to date:
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade sudo apt install -y patchbox-cli
run config scripts
sudo patchbox-config
allows to set the password and the default soundcard
sudo raspi-config
lets you autologin to the console. Source (German)
Copy your files onto the RaspberryPi
to exit the ssh connection and return to the shell of your computer use the command
exit
change into the local directory of your patches
cd /Documents/Pd/path/to/patches
scp to copy the pd files to the RaspberryPi. (Source)
scp startupPatch.pd patch@patchbox.local:/Pd/
For testing purposes our file is called startup.pd and looks like this:
Make a startup script
Start the text editor "nano" (Source) sudo nano /etc/init.d/startPdPatch Paste the following:
#! /bin/sh ### BEGIN INIT INFO # Provides: Pd patch startup # Required-Start: $syslog # Required-Stop: $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Pure Data Patch startup # Description: ### END INIT INFO case "$1" in start) echo "ending Jack" sudo systemctl stop jack sleep 3 echo "Pd is starting" # Starting Programm pd -nogui -alsa -rt -r 44100 -channels 2 -audioadddev "USB AUDIO CODEC (hardware)" /home/patch/Pd/startup.pd ;; stop) echo "Pd is ending" # Ending Programm killall pd ;; *) echo "Use: /etc/init.d/startPdPatch {start|stop}" exit 1 ;; esac exit 0
then Ctl-O to save and Ctl-X to quit the editor.
To make the script executable, type:
udo chmod 755 /etc/init.d/startPdPatch
Test and make persistent
this should start the Pd patch:
sudo /etc/init.d/startPdPatch start
Ctl-c to abort
sudo update-rc.d startPdPatch defaults
Will schedule the script to be run at startup.
