Getting started

Initial setup

Download and install the latest version of Processing from https://processing.org/download/
Start Processing
In Processing:

Tools > Add Tool… to install the Upload to Pi tool (this allows you to write sketches on your laptop, but have them run on the Pi)

Sketch > Import Library… to install the Hardware I/O library (this allows you to use the expansion header pins from Processing)

Telling Processing which Pi to upload to

In Processing:

Processing > Preferences…

Click the link to the preferences.txt file towards the bottom of the dialog

A Finder window should open
Close Processing completely

e.g. via Processing > Quit Processing
Open the preferences.txt file in a text editor
Find the line starting with gohai.uploadtopi.hostname= and replace the value with the IP address or hostname you want to work with

Uploading a sketch to the Pi

In Processing:

Tools > Upload to Pi

This will stop any sketch currently running on the Pi, and upload and run your current sketch instead. It will also put into the Pi's "autostart" - i.e. automatically launched whenever the Pi gets power.
