Can I install a webbrowser on Unipi Neuron Mervis?

I want to connect a touch display to my Unipi Neuron and launch on this display a webbrowser pointing to the local Unipi browseer, in this way I can stear the system via this touchpanel.

Please advice.

I am using Mervis and:
I want to type cast from a real to time (seconds).

Tried to_time, and gor the following message:
Error L513 Ph_Dosering L513//L513//Ph_Dosering 21 2 expression with type 'real' doesn't fit the generic constraint 'ANY_DURATION' for the input parameter 'in1' in a call to the 'to_time'

Any advise?

Thanks.
