Hello, I have been using (in testing) the sendCommand for the backlight, I am using the ITEADLIB_Arduino_Nextion-master library.
so this was working fine, but jast in last few days its not . ! (love that).
the project is quite complex and running on ESP32, as I said it was testing fine,
all other Nextion / TJC are fine, there are a number pages and lot of info and buttons, the backlight control is simply a sleep mode to set the backlight off / low or 100%,
the code is simply,
sendCommand(“dim = 5”);
or
sendCommand(“dim = 100”);
the library is ITEADLIB_Arduino_Nextion-master, as I said there is a lot of code, and up to now its been fine…
any thoughts?
thanks
