During the audio streaming, I want to send a small data, cmd ... to control the on/off of LEDs.
I would like to ask about the method or any sample to send data/command during the audio streaming task.

'ILI9488' is a LCD controller, not an entire LCD assembly. What board specifically are you using? Most have a BL_EN pin or similar that you can wire to a GPIO to control the backlight.


I am using ILI9486 LCD.
I also can't find any pin name of BL_EN. I already ask the manufacturing company ...

Hi all,
I would like to ask if any one success to turn off the backlight.
I am stucking on this case. (My LCD is ILI9486)

I am using the ILI9486 LCD on my ESP32 project.
However, I am having problem to turn off the backlight of LCD using backlight register.
It seems not work even for dimming the backlight.
I heard that we can use GPIO to turn off the backlight.
I would like to ask if everyone have the pinout or anyway ...
