Dim backlight on ESP32 Terminal

Is it possible to dim the backlight in code on the ESP32 Terminal 3.5?

I too would like to know the answer to this question. Seems reasonably done with PWM, but probably already available via one of the libraries that is in control of the display.

Blindly searching through all the code I found a promising function you may want to check out. I'm in the middle of some deeply involved troubleshooting otherwise I'd explore this. See if the setBrightness function is what you're looking for.

lcd.setBrightness(128);

The range appears to be 0~255.

While development continues at a high pace, the current best way to see what LovyanGFX can do is to look at the example below. It should show you the basics of how to include the library, initialise the display and use the various commands to draw things on the display.
