Hi!
I got a Piano Hat for christmas and I have a weird problem with it.
Keys from C to G (including half tones) work perfectly. The rest of the keys (A and upper including half tones, Instrument, and both octaves) light up when touched but the Raspberry Pi doesn't seem to get their signal. I've tried with the example python apps installed with the Piano Hat script and I get the same resultst in all of them. All the keys light when touched but only from C to G are logged. Where can the problem possibly be? I don't think my GPIO is faulty, and if it was, it would probably not light the keys' leds.
I have a Raspberry Pi 2 with the latest Raspbian Jessie image in an 8GB SD card. It is powered by a 2000mAh charger. Everything else works perfectly.
Thanks in advance!
Joan
