Apologies for the stupid questions, and if this has been covered before.
I recently bought one of these displays to use with a NodeMCU development board. The screen works fine, and I have eventually worked out how to create and load pages to the screen in spite of the poor Nextion documentation.
My problem is that I have no idea how to load information to the screen using the Arduino code. The Nextion libraries just produce reams of errors if I try to use them, and all the other examples I have found seem to focus on reading touch input from the screen rather than pushing status or text updates to it.
Can anyone point me in the direction of some basic stuff that I can use to get me started? It may be so obvious that I can’t see it, but I’m struggling
