Installation

• In the piCorePlayer webgui select "Advanced" on the bottom of the main page.
• Install the extension pcp-sbpd.tcz
• In the Squeezelight Tab, select HiFiBerry DAC Zero/MiniAMP as audio output device
• Create a executable file /home/tc/sbpd-script.sh with the content:

# start pigpiod daemon
pigpiod -t 0 -f -l -s 10

# wait for pigpiod to initialize - indicated by 'pigs t' exit code of zero
count=10 # approx time limit in seconds
while ! pigs t >/dev/null 2>&1 ; do
        if [ $((count--)) -le 0 ]; then
                printf "\npigpiod failed to initialize within time limit\n"
                exit 1 # or however you want to deal with failure
        fi
#       printf "\nWaiting for pigpiod to initialize\n"
        sleep 1
done
printf "\npigpiod is running\n"

# load uinput module - required to be able to send keystrokes
# then set the permission to group writable, so you don't need to run sbpd with
sudo modprobe uinput
sudo chmod g+w /dev/uinput

# issue the sbpd command
sbpd e,22,27,VOLU b,26,PLAY -d

• Backup the configuration in the Main Page
• Under Tweaks add the command /home/tc/sbpd-script.sh to user commands. (Pin numbers depend on setup)
