Is there a way to set the brightness of the LCD?
I didn't see any code in the three examples to do this, and I tried to use the documentation provided for the LovyanGFX library, but the brightness didn't change even when setting it to 0. (The sleep function appeared to work, and the screen blanked, but even then the backlight appeared to be on at the same brightness as before.)
I'm looking for ways to increase battery life while the display remains on, and adjustable brightness would be helpful. Currently, with wifi and the screen active I can get about 1.75 to 2 hours out of a fully charged battery. I'm considering using BLE instead of wifi for data transmission to save a little power, but a dimmer display is probably the easiest way to increase battery life.
Thank you!
