I'm running a tabletop RPG where we keep wanting to play Dramatic Reveal, Rimshot, Sad Trombone and the like to punctuate the action. Looking round there are many sound effects boxes but none of them are customizable.
So I thought that's a nice little Make... RasPi + speakers with a wireless USB numeric keypad and daemon process to listen for the keypress and play the right file... Device::USB seemed to be the right place to look however I can get as far as getting the config data #!/usr/bin/perl use strict; use warnings; use Device::USB; use YAML; my $VENDOR = hex("1d57"); my $PRODUCT = hex('32da'); my $usb = Device::USB->new(); my $dev = $usb->find_device( $VENDOR, $PRODUCT ); print $dev->claim_interface(1); my $conf = $dev->get_configuration(); print Dump($conf); But for the life of me can't find out how to listen for keyboard output The best I can find is while (1) { my $data = `cat /dev/hidraw2 | head -c 7`; my $char = ord(substr($data, 2, 1)); print " $char \n";; } However this fails if you keep mashing the key it stops reading the keyboard output. any pointers? -- Michael Lush
