Hi guys,
I have just a little problem: today I decided to upload a new template to the nextion, just to try something new and to my surprise I found that the LEDs (which share the same Arduino together with the Nextion display) have stopped working. Thinking it was the new template I decided to reload the old one. Unfortunately, by reloading even the old template, the LEDs still don't work. I checked if my old mapping was still there and in fact it still exists and it is the one currently selected. I don't understand why they stopped working since all I did was open the tft file and load the new template on the nextion. I have neither changed the Arduino code nor changed the com port. has this happened to you already? Did I forgot something? Can you give me some clues?
Thanks.
Solved:
In the end it turned out that it was all due to bad welding of the wires on the arduino. The reason it stopped working is because, rotating the nextion to disconnect the usb cable and then restart it in order to load the new template, some internal wire moved (my bad, first and last time I didn't hot glued them to the housing 😅)
Thank you guys anyway
