Is the default demo that comes on the unit available for download in .hmi format so we can play with the demo and figure out how it works?
Just now started playing around with mine and otherwise next step is to play with the arduino files. I do not have an Aduino to play with nor have time to learn about them at the current time.
you can download the demo example HMI files here:
And "Annoucement" has posted the quick start for beginers.
Open the demo hmi file by Nextion editor,after you make changes to it,save and compile,then you can click the menu "file"→“Build Folder” to find the tft file.
I don't konw very if 32G SD card is OK,but the format should be FAT32,you can try it.

Have a good time!
