Delay
Delayed sampling is performed after the sampling stop condition is satisfied.
When a sampling stop condition other than the software abort command is satisfied, the PC card
performs sampling for the specified number of times of delayed sampling to store input data to memory.
If you set the number of times of delayed sampling to 0, the PC card stops sampling the moment the
sampling stop condition is satisfied.
Event
”Event” works as a function for reporting the occurrence of a certain PC card state to the application.
The following events can be used in combination depending on the specifications and purpose of the
application.
-
”AD conversion start condition satisfied” event
This event occurs when the AD conversion start condition is satisfied. The event is nullified when
the conversion start condition is “software”.
-
”Repeat end” event
This even occurs whenever a repetition is completed.
-
”End of device operation” event
This event occurs when the entire operation including repetitions is completed.
-
”Stored specified sampling times” event
This event occurs when sampling has been performed for the number of times set by software.
This event can only be used in device buffer mode.
-
"Specified number of transfers" event
This event occurs each time a specified number of samples (set by software) has been completed.
This event can only be used in user buffer mode.
- Overflow
event
This event occurs at an attempt to store input data with the memory full.
-
Sampling clock error event
This event occurs when conversion stops as an error occurs due to a sampling clock period that is
too short.
-
AD conversion error event
This event occurs when conversion stops due to an AD conversion error.
2. Starting/Stopping Operation
Sampling is started by the software command.
Once started, sampling can be stopped by the software command at any timing.
