I'm wondering is there a way to have button combinations trigger an event.
For example, say GPIO buttons #1 and #2 are each assigned to play back a sound file. If I hold down buttons #1 and #2 at the same time, can I get the Brighsign to play back a third sound file.
#1 = sound1.mp3
#2 = sound2.mp3
#1 + #2 = sound3.mp3
If not, has anyone used a work-around, say using an Ardunio/micro controller to connected to the GPIO inputs?
thanks in advance
