GIE_GetTriggerDebounce
Acquires Trigger debounce time for filtering the external trig-
ger.
Syntax
C/C++
short GIE_GetTriggerDebounce (U16 wCardNumber,
U32 * Debounce);;
Parameter(s)
wCardNumber:
Retrieved from the return value of
SmartPoE_Register_Card.
Debounce:
1µs to 200000µs
Return Code
No error occurs if return value >= 0, and if negative value, as
follows
-2
An invalid wCardNumber parameter,
wCardNumber is less than 32
-5
The function is not supported by this card.
GIE_SetTriggerDebounce
Sets trigger denounce time for filtering the external trigger.
Syntax
C/C++
NOTE:
NOTE:
When the board connects with different trigger source types
(voltage and frequency), photocouplers onboard experience
slightly different rising and falling times, and, thus, the trigger
debounce time is 25 to 35 ns longer than the time period (recip-
rocal of frequency) of the trigger source.
