I think you just saved my life: at 1:09 you changed the NexConfig.h file to force the Nextion display/touch panel to communicate with Serial2. This works on ESP32! Then you don't have to disconnect the Nextion wires every time you reprogram the ESP32. Thanks for the video!

Thanks! watching your tutorial #6 video helped get my project done. I was so frustrated until I saw you had a config file mod. Wish I had seen this video before that.
Thanks much, your videos are a great help. I am using a low-cost USB logic analyzer to monitor the serial communications and debug my Nextion code. The Kingst LA1010 for $80 works swell. I tried using a Rigol scope to analyze the serial data, but the dedicated logic analyzer works better.
Thank you for this tutorial!!! I would not have succeeded without your help. I am sending and receiving data on a Teensy 3.2. The only part that does not work is de j0 Progress bar as a button press. The compiler gives an error. But I don't need that part, so I leave it.Thanks again!!!
thanks for the video! I think most of us wish that you make a realtime video where you make a project of nextion and arduino where you step by step without jumping over any steps, what to do.
Really? Do you think that would be interesting and useful? I mean, what else can I really show that I didn't already showed? I try not to be too boring. I use my examples as templates for my new projects. Nothing new or special about creating a new project. Do you have troubles creating your projects?
But what are the things that you guys want to see? I mean, about what would be the project? What parts are you guys having trouble understanding how to do?
Its the Step by Step, to follow easily. You are such a smart guy, that it looks everything is no problem for you, but most of us, would love to have a step buy step guide. From start to finish a small project. Really like read and write data. Make a multi part series out of it. It would be awesome!!! Make it as easy as possible, and be sure you will can make a lot of money with it if you use a adlinks, because coding is not everyones love - and technic and coding is often ?² :-) And the solution is always a good teacher. Because nothing is hard to learn if you have a good teacher! You could be this one!

Hello I use Nextion with ESP32 and i changed config.h and upload.h files , commented debug and use serial2 and use 250000 as baudrate , but touch of display sometimes doesn't work correctly and after 4 or 3 times struggle with it , its work, Do you have any solution?
I don't know. Your setup is so different than mine. I suggest trying exactly my same setup and exact code first. If that works without problems, then change one thing at the time. Maybe first change the module from arduino nano to ESP32. Making sure that works, then change another thing like maybe the baud rate. Etc. One variable at the time.

So you can send data to the nextion display fine? The problem is with a button in the display to send data to Arduino? With such little information about the problem, I can't do much

I don't know what you mean
Hello, i have an good message and an bad message: The good one: I have finished turbine.^^ The bad one it will never run again. SOMEONE (my friend) thought its an good idea to start the engine by hand... He had an firetorch. but he was clever enough to start the turbine from the front. then he judt walked by the back and was lets say he was an middle steake and now lays in the intensive station in an Hospital. oh and as i wanted to help him i have destroyed the turbine by killing it with an fire thing ( you know the thing which is big and red and used to put fire out. have forgot the name) The metal cooled down and the turbine was just crap from there on. But thats the Update for my turbine ^^
Are you kidding? If what you say is true, then your friend is very stupid. How old is he? The name of the metal red thing is called extinguisher.
InterlinkKnight oh thanks for thr name. Yeah he isnt the cleverest one. His belly is burned thats why he is in the intensive station
😂😅
