_8136_S_Get_Int_Status(Cardno, AxisNo, Status)
Use Thread to deal with Interrupt under Windows NT/95
In order to detect the interrupt signal from PCI-8136 under Win-
dows NT/95, users must create a thread routine first. Then use
APIs provided by PCI-8136 to get the interrupt signal. Each card
has 7 events for these interrupts. Event 0 ~ 5 stands for channel
0~5 and event 6 stands for timer interrupt and alarm interrupt. The
sample program is as follows:
Situation : Assume that we have one card and want to receive
Timer interrupt.
Steps :
1. Define a Global Value to deal with interrupt event
HANDLE hEvent[7];
volatile bool ThreadOn;
2. In Initializing Section (you must Initialize PCI-8136 prop-
erly first), set interrupt types and enable an event for
each axis.
_8136_S_Set_Int_Factor(0,0, 0x40);
_8136_S_INT_Control(0,1);
_8136_INT_Enable(0,&hEvent[0]);
Note: For each card, you must assign a 7-events-array in
_8136_INT_Enable
function.
