Use Events to handle interrupts under Windows
To detect an interrupt signal from the card in Windows, you must
first create an events array, then use the functions provided by the
card to obtain the interrupt status. A sample program is listed
below:
Steps:
1. Define a Global Value to deal with interrupt events. Each
event is linked to an axis
HANDLE hEvent[4];
2. Enable interrupt event service and setup interrupt factors
and enable interrupt channel
_8164_int_enable(0,hEvent);
_8164_set_int_factor(0,0x01); // Normal Stop
interrupt
_8164_int_control(0,1);
3. Start move command
_8164_start_tr_move(0,12000,0,10000,0.1,0.1);
4. Wait for axis 0 interrupt event
STS=WaitForSingleObject(hEvent[0],15000);
ResetEvent(hEvent[0]);
if( STS==WAIT_OBJECT_0 )
{
_8164_get_int_status(0, &error, &event);
if( event == 0x01 ) …… ; // Success
}
else if( STS==WAIT_TIME_OUT)
{
// Time out, fail
}
