Hello I run the measure project in the folder C:\Keil\ARM\RV30\Examples\Measure and I found that if the target is simulation, a tool box containing "Update windows", "My status Info", "Analog0 0..3V","Stop Analog0" items appears. I tried to find what defines the itmes in the tool box and I found that they are defined in the Measure.Opt as OPTBT 0,(My Status Info)(MyStatus()) OPTBT 1,(Analog0 0..3V)(Analog0(3.0)) OPTBT 2,(Stop Analog0)(signal kill analog0). But I don't know how to set the items in the tool box by GUI of Keil IDE. Will someone tell me how to do? Thanks.
