RasPiArduino

Includes raspberry_pi_revision from Andrew Duncan

Arduino Framework for RaspberryPI

Features

• The familiar Arduino API
• pinMode/digitalRead/digitalWrite/analogWrite
• Full SPI, Wire and Serial compatibility
• Access to STDIN/STDOUT through the Console class
• Access to system tty through the TTY library
• Process, FileIO, Client, Server and UDP implementations through the Bridge library

Instructions for Arduino IDE

• Open the installation folder of Arduino IDE
• Create a folder named "RaspberryPi" inside "hardware" and clone the repository to a folder named "piduino"

  mkdir hardware/RaspberryPi
  cd hardware/RaspberryPi
  git clone https://github.com/me-no-dev/RasPiArduino piduino

• Download , extract and copy the toolchain to piduino/tools/arm-linux-gnueabihf
  • Windows: gnutoolchains.com
  • The toolchain for Jessie will work ONLY on RaspberryPi 2
  • The toolchain for Wheezy will work on ALL RaspberryPi boards (recommended)
  • Video Instructions
  • Linux 64: arm-linux-gnueabihf
  • Linux 32: arm-linux-gnueabihf
  • Mac OS X: arm-linux-gnueabihf
• Restart Arduino IDE and select the RaspberryPI from the list of boards
• Compile a sketch
• Select the RaspberryPi from the list of Ports (will show the IP address)
• Upload your sketch and see it go

Instructions for the PI

• Install Raspbian Jessie on your RaspberryPI

• Gain root permissions

  sudo su

• Enable password login for root

  passwd

  • enter the new root password twice
  • Edit /etc/ssh/sshd_config and make sure that the following lines exist and are not commented

    PermitRootLogin yes
    PasswordAuthentication yes

• Disable Serial Console on boot by removing console=/dev/ttyAMA0 from /boot/cmdline.txt (or through raspi-config)

• Disable Serial tty

  systemctl disable serial-getty@ttyAMA0

• Disable loading sound kernel module

  sed -i "s/dtparam=audio=on/#dtparam=audio=on/" /boot/config.txt

• Change the hostname for your Pi (optional) (also through raspi-config)

  hostnamectl set-hostname piduino

• Setup WiFi (optional)

  cat > /etc/wpa_supplicant/wpa_supplicant.conf <<EOL
  ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
  update_config=1
  network={
  ssid="your-ssid"
  psk="your-pass"
  }
  EOL

• Setup avahi service to allow updating the sketch from ArduinoIDE

  
  cat > /etc/avahi/services/arduino.service <<EOL
  <?xml version="1.0" standalone='no'?><!--*-nxml-*-->
  <!DOCTYPE service-group SYSTEM "avahi-service.dtd">
  <service-group>
  <name replace-wildcards="yes">%h</name>
  <service>
  <type>_arduino._tcp</type>
  <port>22</port>
  <txt-record>board=bplus</txt-record>
  </service>
  </service-group>
  EOL

service avahi-daemon restart

* Install telnet and git
```bash
apt-get update
apt-get install telnet git

• Copy all files from tools/arpi_bins to /usr/local/bin

  git clone https://github.com/me-no-dev/RasPiArduino.git piduino
  chmod +x piduino/tools/arpi_bins/*
  cp piduino/tools/arpi_bins/* /usr/local/bin
  rm -rf piduino

• Create symbolic link for run-avrdude

  ln -s /usr/local/bin/run-avrdude /usr/bin/run-avrdude

• Synchronize time and start sketch on boot (optional)

  
  apt-get install ntpdate
  cat > /etc/rc.local <<EOL
  #!/bin/sh -e

_IP=\$(hostname -I) || true if [ "\$_IP" ]; then printf "My IP address is %s\n" "\$_IP" fi

Sync Time

ntpdate-debian -u > /dev/null

Start Sketch

/usr/local/bin/run-sketch > /dev/null

exit 0 EOL

* Prevent some RealTek USB WiFi from sleep (optional) (EU)
```bash
echo "options 8192cu rtw_power_mgnt=0 rtw_enusbss=1 rtw_ips_mode=1" > /etc/modprobe.d/8192cu.conf
echo "options r8188eu rtw_power_mgnt=0 rtw_enusbss=1 rtw_ips_mode=1" > /etc/modprobe.d/r8188eu.conf

• Disable screen blank (optional)

  sed -i "s/BLANK_TIME=30/BLANK_TIME=0/" /etc/kbd/config
  sed -i "s/POWERDOWN_TIME=30/POWERDOWN_TIME=0/" /etc/kbd/config

• Do not load I2C UART or SPI kernel drivers

• reboot

If everything went well

Selecting the board from the list of ports

Password prompt before upload
