Start device object
Note: You cannot use the legacy interface on 64-bit MATLAB®. See Working with the Session-Based Interface to acquire and generate data on a 64-bit MATLAB.
When start is issued for an analog input or analog output object,
The callback function specified for StartFcn is executed.
The Running property is set to On.
The start event is recorded in the EventLog property.
Data existing in the engine is flushed.
Although an analog input or analog output object might be executing, data logging or sending is not necessarily initiated. Data logging or sending requires a trigger event to occur, and depends on the TriggerType property value.
For any device object, you can specify start as the value for a callback property.
ai.StopFcn = @start;
Note You typically execute a digital I/O object to periodically update and display its state. Refer to the diopanel example to see this behavior.
If you want to synchronize the input and output of data, or you require more control over when your hardware starts, you should use the ManualTriggerHwOn property.
