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

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)

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
