@zander I bought two genuine Nextion HMI's on Amazon. The first one I bought was a 3.2" for $40, which I used to do most of the development work. ...

@zander based on advise by another user to make the ESP32 port2 work on the Nextion. It works fine. I did not try it without modifying the librar...

I'm going to create a new topic titled "ESP32 to Nextion Lessons Learned.

Bill, I recently watched your video on multimeters and found it very interesting. I'm a retired GE Field Engineer and had many trips dragging a Tektr...

@huckohio @zander Mike, thanks for all your help, I was able to get the ESP32 and Nextion display to communicate. I ended up using the EasyNextionL...

@huckohio Got it, thanks. I thought those were connectors. Makes sense now that I know they are logic level converters. What device did you use for...

Mike, thanks for the quick reply. You did a nice job of documenting the project, something I always try to do also. It makes trouble shooting in the...

Thanks, I've decided to use a standalone 12v to 5v DC to DC converter with built in surge and noise suppression. I'll be using a TVS on the 12v supply...
