ADLINK PCI-8144 - Manual (Page 149)

Function Library 139
the function returns when the state of any one of the interrupt
factors you specified in GpioIntFactorInBits is signaled. In the
latter case, you can check which factors whose state caused
the function to return by compare the parameter “GpioIntTrig-
geredInBits”.
I32 TimeOutMs : Specifies the time-out interval, in millisec-
onds.
I32 *GpioIntTriggeredInBits : Information of interrupt
state in bit format.
Z The value of each bit means: 0: not triggered, 1: be trig-
gered
Return Values:
ERR_NoError
ERR_ParametersInvalid
ERR_DeviceNotInitial
ERR_InsufficientMemory
ERR_InterruptNotEnable
ERR_Win32Error
Example:
I32 GpioIntFactorInBits = 0x101; //Wait DI Ch0
falling edge and rising edge
ret = _8144_set_gpio_interrupt_factor( CardId,
GpioIntFactorInBits);
// wait multiple GPIO interrupts…
I32 TimeOutMs = 10000; //10 sec timeout
I16 WaitOption = 1; //wait all interrupts occured
I32 GpioIntTriggeredInBits;
ret = _8144_wait_multiple_gpio_interrupt(
gCardId, GpioIntFactorInBits, WaitOption,
TimeOutMs, &GpioIntTriggeredInBits );
if( ret == ERR_NoError ){
// Interrupt be triggered
}else{
//Timeout or wait failed
}
_8144_set_gpio_interrupt_factor( gCardId, 0 ); //
Disable GPIO interrupt
