Picade HAT (Device-tree Overlay)
This repository contains the software you need to get started with your Picade HAT.
Before you continue, you should make sure that you're running the latest RetroPie, have your Pi connected to the internet and have a keyboard ready to run through the setup steps.
If you want to use the old Python driver for Picade HAT, see
Create yourself a new RetroPie SD card with the image found here: https://retropie.org.uk/download/
If you're using a Pi 3, or a Pi with a wireless adaptor, you can also drop a
wpa_supplicant.conf into the BOOT folder.
On first boot, at the control config screen hit F4 to exit to the command-line.
If you dropped a
/boot, it wont be installed by default, yet, but now it's easy to set up your WiFi like so:
sudo cp /boot/wpa_supplicant.conf /etc/wpa_supplicant/ sudo ifdown wlan0 sudo ifup wlan0
One-line Installation (Recommended)
Before setting up your RetroPie config, just hit F4 and then type:
curl -sS https://get.pimoroni.com/picadehat | bash
Setup will continue automatically.
When it's finished, you must reboot.
Finally, bind your input as normal!
Clone this GitHub repository somewhere onto your Pi:
git clone https://github.com/pimoroni/picade-hat
Enter the new directory:
Run the installer:
Bind your controls and enjoy!
This overlay supplies all of the functionality for Picade HAT using built-in drivers on the Raspberry Pi.
- Bind the 14 buttons to linux keycodes from a virtual keyboard input
- Optionally: bind the power button to KEY_POWER to trigger a shutdown
- Optionally: assert BCM4 upon shutdown, to cut the power from the HAT to the Pi
- Optionally: set up i2s audio to work with Picade HAT
- Optionally: re-route the Pi's act LED and give you control over the trigger function
Once installed, you can change the line in
/boot/config.txt to customise your Picade HAT install:
Bind up/down/left/right to wasd and disable digital audio:
Only use the default keyboard bindings, no other features:
Set the act LED to show cpu0 activity:
Note: There's an 80 character line-length limit for
If you want to change many parameters you should use the
dtparam command like so:
dtoverlay=picade dtparam=up=17 dtparam=down=31 dtparam=left=30 dtparam=right=32 # etc
See picade.txt for full documentation.
Manually Building & Installing
You can run
sudo make install to install
picade.dtbo in your
Once done, edit
/boot/config.txt and add
dtoverlay=picade to the bottom.
See picade.txt for the various options you can supply to this command.
