twinklr_pde is a Processing application that is the core of "Twinklr", a physical, digital musicbox.

It's designed to be run fullscreen on a Raspberry Pi with touchscreen, though it'll work on any desktop computer running Processing.

Twinklr is written for Processing 3.0.

You'll need the following libraries, installable through the Processing library manager:

• Beads
• The MidiBus
• Ani
• IO

You'll also need Pui installed in your libraries directory.

Once Twinklr has loaded, you can either use it with a mousewheel, or, if running it on a Pi, a quadrature encoder connected to pins 17 and 27.

To make Twinklr run on a Raspberry Pi with 7" touchscreen, there are a few obvious tweaks you'll need to do.

1. Uncomment the import of processing.io.* in the main file
2. Comment out the size directive in the same file
3. Uncomment the fullScreen and noCursor directives in the same file
4. Uncomment all the GPIO directives in the same file
5. rename io.pde.pi to io.pde

Then, the whole application should compile and run fullscreen on the Raspberry Pi.

shutdown.py should be run at startup on the Pi. It waits for pin 18 to go low, and when it does, it shuts the Pi down.
