(BYTE
b_BoardHandle,
BYTE b_CounterOrTimerSelect,
LONG l_ReloadValue,
BYTE b_ContinuousOrSingleCycleSelect,
BYTE b_HardwareOrSoftwareTriggerSelect,
BYTE b_HardwareOrSoftwareGateSelect,
BYTE b_InterruptHandling)
Parameters:
BYTE b_BoardHandle Handle of the xPCI-1500
BYTE b_CounterOrTimerSelect Selects the mode of the 2
nd
counter/timer
- APCI1500_TIMER :
The 2nd counter/timer is used as a timer
- APCI1500_COUNTER :
The 2nd counter/timer is used as a counter
LONG l_ReloadValue This parameter has two meanings.

Each time the counter value or timer value
is set to "0", l_ReloadValue is loaded.
- APCI1500_SINGLE:
If the counter or timer value is set to
"0", the counter or timer is stopped.
BYTE b_HardwareOrSoftwareTriggerSelect:
- APCI1500_HARDWARE_TRIGGER:
The input 12 is used for the trigger.
If this input channel is on high, the
start value is re-loaded.
- APCI1500_SOFTWARE_TRIGGER:
Input 12 has no influence on the trigger
BYTE b_HardwareOrSoftwareGateSelect :
- APCI1500_HARDWARE_GATE:
The input 13 is used for the gate.
If this input channel is on high, the
counter/timer is started.
If this input channel is on low,
the counter/timer is stopped.
- APCI1500_SOFTWARE_GATE:
