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

• Setup SSH over USB for the Pi Zero
• Setup WiFi for the Pi Zero

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
  • See: ​http://www.savagehomeautomation.com/projects/pi4j-connecting-java-to-the-raspberry-pi.html
  • ​video tutorial
  • Easy way, type:

      cd ~/dev
      curl -s get.pi4j.com | sudo bash
    

• Run a program at startup of Pi/Raspian?:

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
