6230 DIO programing hoping the helper

[jude.xu]

I want to use the DIO function of 6230 ,i used the following function,but  the printf() function give me  0XFF ,and the port of  the card 6230 did give me high voltage. can any body tell me why?

thank u very much.

function DO_out ()

{ 

 tAddressSpace  _Bar1;
 tstaticDIO *_board;
 
 _Bar1 = bus->createAddressSpace(kPCI_BAR1);
 _board = new tstaticDIO(_Bar1);

 //Configure Digital lines of Port 0 as Output
 //_board->IOSelect0.writeDirection(_board->IOSelect0.kDirectionOutput);
  
 //Write 0x01 to the port 0, output can be checked by putting a break point.
 _board->IOPort0Data.writeRegister(0xC0);
 _board->IOPort1Data.writeRegister(0x03);
 printf("\nWriting to Port 0...\n");

 //Read the digital pattern.
 //uPattern = _board->IOPort0Data.readRegister();

 printf("_board->IOPort0Data.readRegister() is 0x%x \n",_board->IOPort0Data.readRegister());
 printf("_board->IOPort1Data.readRegister() is 0x%x \n",_board->IOPort1Data.readRegister());

 delete _board;
 bus->destroyAddressSpace(_Bar1);

}
