Nextion+Arduino Tutorial #5 Troubleshooting

I go through the most common problems when trying to use the nextion display with arduino, and the solutions.

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.

Thank you for your very good tutorial. I manage to get a program initially made for uno on my mega arduino board ! Keep on the good work.

감사합니다. 동작이 안되었는데 이영상덕분에 정상적으로 동작하게되었습니다. 많은 도움이되었어요 ^^😄😃😃

Do you have any information on using the popup keyboard and keypad on the edior. i cant find much about using them online. thanks

[ericksonengineering]

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.

Thank you sir for this tutorial ❤ . its very helpful to configure the error in the serial communication between nextion and arduino. God bless 😇.

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?

[plageran]

Thank you so much dude! I've been struggling to get a reading on a NE555 chip via arduino. I will get your code and disect the bits i need. I guess using 1 of the pins as a input won't work, will try the RX pin

[hanifahyulihandinipurbon]

i have problem, when i running in simulation nextion editor program work well, but when i nextion button doesn't change and rx tx in arduino doesn't blingking

[mbsingh]

hello, I bought 2 display 7" enhanced. One is working and on 2nd display, our firmware is visible and touchscreen works but our amplifier does not rx any commands from it nor Display rx any from the amplifier so RX/TX data lines not working. What could be the reason and how to deal with it? Please suggest. Thank you.

Hi, i have a question, why cant i use my nextion display in arduino NANO but i can use it with the same code on the arduino UNO

[mbuntugnugnu]

Hello! Why using the debug window on the nextion software everything works correctly, while between the arduino uno and my nextion display does not work?



Thanks for the great job you did.

Hi, i've a little probleme with an arduino mega, i can't get it work with your #2 example on the serial 1/2/3, only on serial(0). Have you got an idea ?

When Verifying the sketch, it's giving me this error in the console. 'NexButton' does not name a type; did you mean 'Nextion'?

It has an issue with every single one of my buttons, I've followed your tutorial, and I didn't do anything wrong. Is this code still working after updates to the Nextion library?

NexButton w3 = NexButton(0, 4, "w3");

EDIT: My Nextion Library folder isn't NEARLY as full as yours, could you provide the library you're using so I can download it? My folder has 7 files total, Nextion.h is a notable one.

EDIT 2: Found it, that was harder than it should have been. I hope this is my solution. I got my nextion library from the official Arduino add library list.

For Arduino Uno Postinitialize Event did the trick or if I use 9600baud in Arduino sketch

Hey, I was uploading in my nextion display and suddnly an error of "Timeout" appeared and the upload stopped at 41% After that I tired again and now it doesn´t reconginze the nextion anymore. Do you know what it could be? Thanks

[jansmith]

Thanks for the video! Probably a stupid question but when I look at my serial monitor there are three reversed question marks on the place where "0xff" should be. How do I fix this? because the serial communication between my arduino and nextion still don't work.
