NexButton not a name
Where is your the Nextion.h file?
Where did you get your Nextion.h file?
ithink the problem is with my arduino ide
Make sure there are not other libraries for Nextion
Once you have downloaded the Iteadlib as a zip
Sketch -> Include Library -> Add .ZIP Library
Select the Iteadlib zip file
You may need to delete folders and redo
Library Manager doesn't do delete libraries
- got to love Arduino
