Nextion. What library to use?

Hi!

I’m new to Nextion. As I’ve understood, there is quite a few libraries, but I can’t figure all out.

I’ve set up a simple layout with mostly dual state buttons. They will control relays.

At one point I actually got to change the output for one pin, but could not change it back.

Have tried different libraries and their examples, with obscure results. I need to start from scratch with some helpful hints from you.

I’m using a Arduino Mega, and 3.2" enhanced Nextion.

So where to start? With what library? Simple code example?

Did you tried Nextion original library ? Library

YouTube. There are LOTS of examples for how to get Arduinos and Nextion displays to talk.

Yes, I’ve tried three different including the original. Each with their own separate flaws and different ways of approach.

I was hoping some experienced user would have some directions or point me in the correct way to figure out my mentioned problem.

I don’t use Arduino AVR MCU. I wrote my own lib for the Microchip PIC MCUs. but its not stand alone yet.

What is the problem ? may be some video lessons of usage available on the Internet ?

I just searching Google 1-st link is : https://randomnerdtutorials.com/nextion-display-with-arduino-getting-started/

Have you looked at the examples on the Nextion web site? Watched any YouTube videos? There are many out there and you should be able to figure it out pretty easily.
