_8144_get_gpio_output
Get all DOUT digital output signal
Description:
Get all DOUT digital output signal.
Syntax:
I16 _8144_get_gpio_output( I16 CardId, I16
*DoValueInBit )
B_8144_get_gpio_output( ByVal CardId As Integer,
DoValueInBit As Integer)As Integer
Parameters:
I16 CardId : Specify the PCI-8144 card index. The CardId
could be decided by DIP switch (SW1) or depend on slot
sequence.Please refer to _8144_initial().
I16 *DoValueInBit : The information of DO signals, bit0 –
bit7 => DO CH0-7
Z The meaning of each bit: 0:OFF, 1:ON
Return Values:
ERR_ParametersInvalid
ERR_DeviceNotInitial
ERR_NoError
Example:
I16 CardId = 0; //Card ID number
I16 DoValueInBit;
ret = _8144_get_gpio_output(CardId, &DoValueInBit
);
if( ret == ERR_NoError )
{// compare DoValueInBIt…}
