GPIO trigger

The photobooth uses the 'c' key as a trigger to start the photobooth. A device-tree overlay can be added to configure gpio_1 as a keypad 'c' button.

Compile and install the photobooth_button.dts on the pi using:

sudo dtc -I dts -O dtb -o /boot/overlays/photobooth_button.dtbo misc/photobooth_button.dts

Connect a normaly open button between GPIO_1 and ground.

disable gvfs-gphoto:

gvfs-gphoto automatically mounts cameras as a storage device on boot, this prevents cheesypic from using them. To disable gvfs run:

sudo systemctl mask gvfs-daemon
systemctl --user mask gvfs-daemon

Finally add the following line to /boot/config.txt:

dtoverlay=photobooth_button

Printer Setup

add the user to the lp group

sudo adduser $USER lp

Add your printer to cups using the cups webpage or lpadmin command.

Set the default printer:

lpoptions -d printer-name

Verify the default printer:

lpstat -d
