Please I need help. I'm building this wireless handheld http://www.trainelectronics.com/DCC_Arduino/Nextion_LCD/index.htm Something is wrong with the Nextion 3.2 basic display NX4024T032 3.2 or with the display programming, various keys when I touched do not change their color or show that they have been switched, only 3 keys change color and status. I uploaded a video on YouTube demonstrating the problem the link is below. Could you help me to solve this problem? thank you Hamilton
I've been using Nextion displays since late 2016, and back then the libraries for Arduino was full of bugs and hardly worked at all. This could be the case for you. Maybe there are some now that works, I don't know. Anyway, I don't use any Nextion library, instead I just send and receive serial commands/strings. Of course this means you have to do some programming and it is maybe not for absolute beginners.
