Falcon Player GPIO DO_NOT_PRESS Button Scripts

do-not-press-down.sh

#!/bin/bash

# do-not-press-down.sh runs when the physical DO NOT PRESS button is depressed.
# This is designed to provide feedback as to whether or not the button release
# will activate a sequence. If the $PREFIX is not already playing, this runs
# an ok sound + effect. If $PREFIX is already playing (somebody is spamming
# the button), this runs an err sound + effect. Either way, the sound + effect 
# will play in the background without interrupting anything already playing.
# For this reason, use short sounds and sequences with this script (under 1
# second).

do-not-press-up.sh

#!/bin/bash

# do-not-press-up.sh runs when the physical DO NOT PRESS button is released.
# This script is designed to trigger only one $PLAYLIST item per push. Each
# successive run of this script should play the next $PLAYLIST item or cycle
# back to the beginning. If a $PLAYLIST item is already playing (probably from 
# a previous button push), this script will stop that item, returning to 
# whatever was running prior to starting the last $PLAYLIST item.
