Display event information when an event occurs
||An serial port object.
||The event that caused the callback to execute.
displays a message that contains the event type, the time the event occurred, and the name of the serial port object that caused the event to occur.
For error events, the error message is also displayed. For pin status events, the pin that changed value and its value are also displayed.
You should use
instrcallback as a template from which you create callback functions that suit your specific application needs.
The following example creates the serial port objects
s, and configures
s to execute
instrcallback when an output-empty event occurs. The event occurs after the
*IDN? command is written to the instrument.
The resulting display from
instrcallback is shown below.
Read the identification information from the input buffer and end the serial port session.
