There is some kind of a summary halfway this topic. I agree, it deserves a proper one, but I simply have no time.waspie wrote: ↑21 May 2018, 01:26I just got my first nextion and i'm already making some progress. I have to say, it's a bit confusing... someone should make a nice noob summary at some point (pointing at me too, don't worry )
This will be great with openhab / mqtt. I don't plan to use a slider yet, but i may at least test so I can help answer arnold's question.
I think I know the answer to this already but I'll ask anyway.
Is there any way to remotely update the Nextion? I'd love to get this pinned to a wall and halfway usable but i also need a way to update it. I know i'll be tinkering with the interface until i get it just right.
I didn't see much in the way of updating it remotely. I hate the thought of actually having to finalize some sort of design before getting it on the wall. that could take months :O
also, all the spec sheets i've looked at from the current ones show +3.3v max on the serial line. maybe older ones used 5v?
Remote update would be awsome, but I honestly have no clue how to do it.
I have my displays direcly connected to WeMos boards without any problem. If you interprete the description of the interface, you see it gives an output of max 3.2 volts, but accepts between 3.3 and 5 volt as a logic high at its input.
