Music Shield pins D0-D9 - How to use for my own application?

Hi, when I comment out InitIOForLEDs(), this approach works.

Card found, starting... Ok.

Sectors per Cluster: 64
FAT Start sector: 142
Root start sector: 608
Data start sector: 512
ClockF:B800


Found file name is 2GUNS   MP3
File size: 4554880bytes.

When I comment out InitIOForKeys(), this does not work. Music doesn’t play and I get this:

Card found, starting... Ok.

Sectors per Cluster: 64
FAT Start sector: 142
Root start sector: 608
Data start sector: 512
ClockF:B800

Did you try this and get a different result?

I don’t understand this code well enough to modify it to do something different:

void InitIOForKeys()
{
	#if defined(__AVR_ATmega1280__)|| defined(__AVR_ATmega2560__)
	DDRH &= ~(1<<VD);
	DDRH &= ~(1<<BK);
	DDRE &= ~(1<<PS);
	DDRG &= ~(1<<VU);
	DDRE &= ~(1<<NT);
        //internal pull-high
	PORTH |= (1<<VD | 1<<BK);
	PORTE |= (1<<PS | 1<<NT);
	PORTG |= 1<<VU ;

	#else
	DDRD &= ~(1<<VD);
	DDRD &= ~(1<<BK);
	DDRD &= ~(1<<PS);
	DDRD &= ~(1<<VU);
	DDRD &= ~(1<<NT);
        //internal pull-high
	PORTD |= (1<<VD | 1<<BK | 1<<PS | 1<<VU | 1<<NT);
	#endif
}
