Hi Christian,
there are indeed some restrictions to use the parameter system when fields do not allow to enter a text yet.
This is a problem for drivers for Instrument modules that come with a fixed user interface. For drivers for instrument modules with a ‘Parameters’ section like Logger, Switch, Robot or in CustomFunction script, it is possible to define a field to be a string input.
In case of a Selection field (i.e. a drop-down box), there is no good solution yet as changing it into a string input would lead to the loss of the options. A good compromise could be that such a Selection field becomes usable as Combo box, i.e. a drop-down box where the user is still able to select pre-defined options, but can also type in an own value or use the parameter syntax {…}. The driver than would need to check whether the handed over value is reasonable and applicable to the instrument.
It means that we would need to do some modifications to SweepMe! to make this possible.
If you would like to further discuss this new topic, could you please open another topic here in the forum? There you could also highlight, which fields are affected.
Thanks and best
Axel
