Baseline Minibot Raspbian Image Build Instructions

• Plan A: note that some of the below install steps may already be in the stock image, so don't worry about it if they're already installed)
  1. Download stock ​Raspian Jessie Light image
  2. Follow ​these directions for installing it to a uSD card

• Plan B:
  1. Download and install ​PiBakery which includes Jessie Light

• Setup IP over USB for the Pi Zero

• Install ​PuTTY and use it to connect to the Pi:

Hostname: raspberrypi.local Username: pi Password: raspberry

• Update to latest software (this will take a while):

    sudo apt-get update
    sudo apt-get upgrade
  

• Install some useful packages:

    sudo apt-get install i2c-tools
    i2cdetect -y 1
  

• Install Oracle Java JDK. Do not use stock OpenJDK, its slower.

    sudo apt-get install oracle-java8-jdk
  

  • Then test, by running java -version. It should say java 8, not openjdk.

To access the I/O capabilities of the Pi (and the PiBot hat), you must install additional libraries; either Oracle's Device I/O (DIO) or Pi4J (which uses WiringPi?) or both. You can read about them ​here. Tutorials are ​here and ​here

• Install ​Pi4J

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

• Test installation by checking version: pi4j -v
• Install Oracle ​Device I/O (DIO) library. See usage ​here and [​http://www.oracle.com/technetwork/articles/java/cruz-gpio-2295970.html

    sudo apt-get install mercurial
    hg clone http://hg.openjdk.java.net/dio/dev jdkdio
    cd jdkdio
    export JAVA_HOME=/usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt
    export PI_TOOLS=/usr
    make
    sudo cp -r build/deviceio/lib/* $JAVA_HOME/jre/lib
  

• Test Device I/O following ​these directions

• Install ​Nano text editor sudo apt-get install nano
• Install ​Avahi (mDNS/zeroconf) sudo apt-get install avahi-daemon
• Update Raspian Configuration 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
• Setup WiFi for a Pi Zero
• Reboot one last time, and log back in. Capture OS image for reuse by
  • ???

Per Minibot config instructions (with baseline image above installed)

• Update Raspian Configuration sudo raspi-config
  • Customize host name. Reference hostname list for assigned names. Be sure not to duplicate!
  • Select 'expand to use entire sd card'. This will reboot the pi.

• Doesn't wiringpi get installed as part of Pi4j install??? If not:
  • Install git: sudo apt-get install git
  • Install ​wiringPi:

      mkdir ~/dev;cd ~/dev
      git clone git://git.drogon.net/wiringPi
      cd wiringPi
      ./build  
    

  • ​Install wiringPi
  • Then, test by running "gpio -v" and "gpio readall"
