RE: [avr-gcc-list] Problem with PC Keyboard

Hello

Have you remembered the correct pull up resistors.

Try to change 

U8 edge, bitcount;                // 0 = neg.  1 = pos.
U8 kb_buffer[BUFF_SIZE];
U8 *inpt, *outpt;
U8 buffcnt;

to

U8 edge, bitcount;                // 0 = neg.  1 = pos.
U8 kb_buffer[BUFF_SIZE];
U8 *inpt, *outpt;
volatile U8 buffcnt;

I can't believe that the AN 313 shouldn't work.

Remember to test all the different parts and then combine them.

void InitDevices(void)
{
        // sei(); why ??
        PortInit();
        SpiInit();
        outp(0x8A,MCUCR);
        outp(0xC0,GIMSK);
        // cli(); why ??
}

Use this 

// init devices
init();
// enable int.
sei();
// main loop
while(1)
{
}

Best regards
Rune Christensen
