[ts-7000] Re: Matrix Keyboard on DIO (XDOI)

["Simon" <>]

I don't know if you've solved it at this point, but I just saw it.

What I did to get the XDIO working is:
unsigned char* XDIO_REG1, XDIO_REG2. XDIO_REG3;
unsigned int * start;

start = mmap(blah,blah,blah,0x12c00000);

XDIO_REG0 = (unsigned char*)(start + 0x00);
XDIO_REG1 = (unsigned char*)(start + 0x01);
XDIO_REG2 = (unsigned char*)(start + 0x02);
//XDIO_REG3 = (unsigned char*)(start + 0x03); // I dont use this one

// Set Mode
*XDIO_REG0 = 0x00;

// Set Direction
*XDIO_REG1 = 0xFF; // All output

// Toggle Data
while(1){
  *XDIO_REG2 = 0xFF; // All on
  sleep(1);
  *XDIO_REG2 = 0x00; // All off
  sleep(1)
}

good luck,
-S
