Desktop Preparation

  • On your notebook/desktop, install Bonjour Services from Apple. This allows your windows machine to 'just know' the hostname raspberrypi.local. See Bonjour for Windows
  • Install Jessie Lite to your sd card Raspbian Jessie OS

Configure Pi Zero

  • Connect to Pi: ssh pi@raspberrypi.local (password is raspberry)
  • Configure Pi
    • Setup DNS: sudo nano /etc/resolv.conf .
      • add: nameserver 8.8.8.8
      • add: nameserver 8.8.4.4
    • Configure PiZero? sudo raspi-config
      • Activate the Pi Zero's built-in I2C Interface:
        • Use the down arrow to select 'Advanced Options'
        • Arrow down and select 'I2C'
        • Select 'Yes' to enable the I2C Interface
        • Acknowledge the notification confirming the I2C Interface has been enabled
      • Activate the option "Expand to use the entire memory card." This will reboot the system after you are done, then continue.
    • Update to latest software (this will take a while):
        sudo apt-get update
        sudo apt-get upgrade
      
  • Install Oracle Java JDK: sudo apt-get install oracle-java8-jdk . Do not use OpenJDK, its slower.
  • Install git: sudo apt-get install git
  • Install wiringPi:
      mkdir ~/dev;cd ~/dev
      git clone git://git.drogon.net/wiringPi
      cd wiringPi
      ./build  
    
    Then, test by running "gpio -v" and "man gpio"
  • Install Pi4J

Highlights from this page:

NOTE: Use ‘sudo’ to perform these operations as root in a Raspbian shell…

Create an LSB style init script for launching a PiBot autonomous startup app.

  • I copied rc.local as a starting point and modified it to run my desired - PiBot app as follows:
    • sudo cp /etc/init.d/rc.local /etc/init.d/pibot_auto
    • sudo vi /etc/init.d/pibot_auto
    • Revise the header block to describe PiBot autonomous app
    • Revise the do_start() to launch the PiBot autonomous app
    • Save and exit editor
    • Test/debug the script until it works as desired using these commands:
    • sudo /etc/init.d/pibot_auto start
    • sudo /etc/init.d/pibot_auto stop
    • sudo /etc/init.d/pibot_auto restart When working as desired, register script to run at startup/shutdown:
    • sudo update-rc.d pibot_auto defaults If the script is changed (edited) after registering, a ‘reload’ may be necessary as follows:
    • sudo systemctl daemon-reload To unregister the script (i.e., stop it from running at startup/shutdown):
    • sudo update-rc.d -f pibot_auto remove
