Hello! I am communicating with hardware via GPIB. I am trying to reconstruct software to control the device. Unfortunately, the GPIB bus becomes "clogged" with many nearly synchronous calls to the GPIB. In order to resolve this, I would like to only query the GPIB if a control on the front panel has been changed by the user. For instance, to change a time constant, the user alters the value within the time constant front panel control. A moment later, a query is sent to display what the device has the time constant set as. I would like this query to the device to only be sent if the user has actually changed the time constant control value. All of the calls are looped in a while loop. Is there a simple, light-weight way of checking if a control value has been changed? Thanks in advance for any help!
