HD410 GPIO question...
Hi, I am using the HD410 to playback 1 of 5 MP3 files from pushbutton triggers. My pushbuttons have LED backlights in them which need to come on while the track is playing, and go off when finished. With only 8 GPIO, is it possible to change the state of a GPIO from input to output for a short while, then back to an input? This needs to happen for all 5 buttons. Thanks!
