===== Pduino on Raspberry Pi ===== Controlling an Arduino in Pure Data on a Raspberry Pi.\\ {{:puredata:pd_pduino-gui-help_jan2020.png?|}} [[https://puredata.info/|Pure Data]] (Pd) is a visual programming language developed by Miller Puckette.\\ [[https://puredata.info/downloads/pduino|Pduino]] is a way to interface an Arduino in Pure Data. Writen by Georg Holzmann, Gerda Strobl, Roman Haefeli and Olsen Wolf.\\ The program running on the Arduino is the [[https://at.or.at/hans/pd/objects.html|Firmata]] by Hans-Christoph Steiner, Paul Stoffregen, Shigeru Kobayashi and Jeff Hoefs.\\ \\ This is a workaround for installing Pduino on a Raspberry Pi 4 with [[https://www.raspberrypi.org/downloads/raspbian/|Raspbian Buster]]\\ ---- ==== Arduino and Firmata ==== Install the Arduino IDE: $ sudo apt update $ sudo apt install arduino Open the Arduino IDE: $ arduino Select in -> Tools -> Board and Port. The port looks something like: /dev/ttyUSB0\\ Open the Firmata program: -> open -> Firmata -> StandardFirmata\\ And upload it! ---- ==== Pure Data and Pduino ==== === Install Pure Data === $ sudo apt update $ sudo apt install puredata === Install the Externals === The comport external should be installed via the terminal:\\ $ sudo apt install pd-comport The other externals can be installed in Pure Data. Open Pure Data and in:\\ -> Help -> Find Externals\\ Install: zexy, mapping, cyclone and pduino\\ The Pd external folder should look like that:\\ {{:puredata:pd_external_folder_jan2020.png?|}} === Set Path === In Pure Data -> File -> Preferences -> Path set the paths for the zexy, mapping, cyclone and pduino libraries.\\ It might be /home/pi/Dokuments/Pd/externals/....\\ {{:puredata:pd_path_jan2020.png?|}}\\ === Set for Startup === In Pure Data -> File -> Preferences -> Startup set zexy (it will load on launch)\\ Restart Pure Data.\\ {{:puredata:pd_startup_jan2020.png?|}} === Run Pduino === In //Pure Data/help/Patch Browser/pduino// open arduio-help.pd\\ Click on "devices". The console should tell you witch number your Arduino has.\\ Select that number and click on "open $1".\\ Now your Pduino should work.\\ {{:puredata:pd_pduino-help_jan2020.png?|}}\\ One can test it by clicking on "PinMode 13 output" and then toggel pin 13. The build in LED should turn on and off.\\ \\ Examples:\\ {{ :puredata:pduino_examples.zip |}}\\ ---- ==== Links ==== [[https://puredata.info/]]\\ [[https://puredata.info/downloads/by-category/library]]\\ [[https://github.com/reduzent/pduino]]\\ [[https://playground.arduino.cc/Interfacing/PD/]]\\ ---- ==== License ==== This manual is made by **Wolfgang Spahn** 2020.\\ It is licensed under a [[http://creativecommons.org/licenses/by-nc-sa/4.0/"|Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License]].
