Pirate Audio

Pirate Audio is a range of audio output boards for the Raspberry Pi.

Each board includes an ST7789 240x240 pixel LCD display, four buttons and some form of audio output (except for the Pirate Audio: Dual Mic which offers two microphones instead of audio output).

Hardware

• st7789 display (see Python library)
• four buttons, active low connected to BCM 5, 6, 16, and 24 (A, B, X, Y respectively)

Installation

You'll need to add the following lines to /boot/config.txt to get audio up and running:

dtoverlay=hifiberry-dac
gpio=25=op,dh

You can also disable onboard audio if you're not going to use it, this sometimes helps applications find the right audio device without extra prompting:

dtparam=audio=off

And for Dual Mic, you'll need:

dtoverlay=adau7002-simple

(See Clip Recorder for further example of use.)

Using with Spotify Connect

If you want to display album art and track information on your Pirate Audio LCD then check out PiDi Spotify.

Note: PiDi Spotify is currently in beta, and does not work alongside Mopidy. If you want to smush track information into Mopidy from Raspotify see: #17

Using With Mopidy

We've created plugins to get you up and running with Pirate Audio and Mopidy.

These will give you album art display, volume, play/pause and skip control.

Build Your Own

If you're planning to build your own application you'll find some inspiration in examples.

But first you'll need some dependencies:

sudo apt update
sudo apt install python-rpi.gpio python-spidev python-pip python-pil python-numpy

And then you'll need the st7789 library:

sudo pip install st7789

For more display examples see the st7789 Python library examples.
