Hi Vic


Yesss does it work

but my tx = screen must be connected to mega tx2

= rx screen is mega rx2

weird

I do not know why I have to try to understand the rest and my heating and humidity control project going to start

I think I made the right choice for a touch screen that I see

thank you very much appreciate your help

Graag gedaan

you're welcome


greeting Vic.
