4. Application Development
(3) The measuring is begun after clicked the button of [Start], the conversion's information is displayed.
The sampling number within FIFO :
That is the conversion data is stored at memory, That is more visual displayed in [Memory
Image].
The sampling number when event :
The event is occurred when the input sampling number within FIFO reach this number.
Total Input Sampling Number :
The total sampling number is stored at memory for this application.
The Measuring will stop when this error as follows.
Sampling clock error :
When the application is measuring with internal clock, sampling clock is too fast to process.
When the application is measuring with External clock, clock cycle is too fast. Moreover, noise
is be considered.
Buffer overflow :
The memory has overflowed because the conversion speed is too fast compared with the speed
at which data is taken.
(4) The measuring is stopping after clicked the button of [Stop].
Measuring Analog Output tool
This is an analog output and measurement utility able to sample indefinitely using the FIFO memory.
An event is triggered when the remaining conversion data in memory reaches a specified level and this
causes the new output data to be loaded. The utility also shows a visual representation of the data in the
FIFO memory.
The number of channels, whether to use an internal or external clock, conversion speed, number of times
to sample before generating an event, and number of samples to load at each event can be specified. As
an event is also generated if a sampling clock error occurs, you can use the utility to test the conversion
operation under a range of different conditions.
