GPIO Interrupt Source Bit Settings (1=Enable,0=Disable)
The steps for using interrupts:
1. Use _8102_int_control(CARD_ID, Enable=1/Disable=0);
2. Set interrupt sources for Event or GPIO interrupts.
3. _8102_set_motion_int_facor(AXIS0, 0x01); // Axis0 nor-
mally stop
4. _8102_set_gpio_int_factor(CARD0, 0x01); // DI0 falling
edge
5. _8102_wait_motion_interrupt(AXIS0, 0x01, 1000) // Wait
1000ms for normally stop interrupt
6. _8102_wait_gpio_interrupt(CARD0, 0x01, 1000) // Wait
1000ms for DI0 falling edge interrupt
7. I16 ErrNo=_8102_wait_error_interrupt(AXIS0, 2000); //
Wait 2000ms for error interrupts
