Arduino – Raspberry Pi Development Environment Framingham MakerSpace Presentation Saman Amighi 05/2014 ® Raspberry Pi Foundation

Arduino Environment

Arduino.cc

Java based development C/C++ style coding Downloads of the IDE environment AVR and Gcc/G++ command line utilities

Arduino Raspi Environment

Build and Upload Arduino code on Raspberry Pi Low cost solution Isolate circuitry Allows upload or serial output for multiple Arudinos With a Hub Or multiple Raspberry Pis

Development Environment

Headless Development Where? Work on the Raspberry PI Work on your own Computer How?

Which editor to use Locally - VI, EMACS, NANO, etc. Remotely - Windows- Notepad, Mac – TextWrangler Required native SFTP and backups

Environment Setup

Install latest code on Raspi Using your favorite method Isolate and build a new Raspi SD card apt-get update and apt-get upgrade Make a backup on Windows or SD card Install Arduino 1.0.1

Upgrade to Arduino 1.0.5 (as of May 2014) Install github INO for command line function

Environment Setup (cont’d)

Install Arduino 1.0.1

sudo apt-get install arduino Reference http://tech.cyborg5.com/2013/05/30/irlib-tutorial-part 3d-installing-the-arduino-ide-on-a-raspberry-pi/

Environment Setup (cont’d)

Upgrade to Arduino 1.0.5

cd mkdir downloads cd downloads wget http://arduino.googlecode.com/files/arduino-1.0.5-linux32.tgz

tar zxvf arduino-1.0.5-linux32.tgz

cd arduino-1.0.5

rm -rf hardware/tools Copy all but executables sudo cp -ru lib /usr/share/arduino sudo cp -ru tools /usr/share/arduino sudo cp -ru hardware /usr/share/arduino sudo cp -ru examples /usr/share/doc/arduino-core sudo cp -ru reference /usr/share/doc/arduino-core

Environment Setup (cont’d)

Install github INO (http://inotool.org) Get the ino and python easy install tools git clone git://github.com/amperka/ino.git

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python Install ino sudo easy_install ino Install Serial communication apt-get install picocom

Build and Upload

Plug the Nano to Raspi via USB cable Build the directory structure for blink Build the code Upload the code At this point blink should be running on your Nano Most Important is to identify -m option for board type Example: -m nano328 0r -m prov5328

Debug Environment

Connect the TX and RX of the Arduino using the console cable to USB to the Raspberry Pi (Green to TX to Pin 0, White to RX to Pin 1 of the Arduino) Log the serial output (note Serial.Begin speed) ino serial -b 57600 –p /dev/ttyUSB0 Remember Control a x to stop You can use a hub and program or debug multiple Arduinos

More on ino commands

usage: ino [-h] {list-models , preproc, upload, init, build, clean, serial} init – setup blink or empty sketch clean – erase and clean all build settings build – build the code based on board model upload – upload code to the board serial output – similar to Arduino IDE, work with serial list-models – list board models

Play with Arudino via ino

Use the provided SD or Raspi Login as pi / raspberry cd code2 ino clean ino build -m nano328 ino upload -m nano328 Edit the sketch as you want to do other things

Additional Potentials Firmata

Firmata is a generic protocol for communicating with microcontrollers from software on a host computer.
