I have an ESP32-S2 connected to a st7789v display, where there is no backlight control on the display…
I wonder, if I could use different colors (intensity) to “dim” the display during evening hours ?
Currently the display have a 10 second refresh, and I wonder if I could use a boolean helper/sensor to check whether the display should stay “blank” on a refresh, or the code to update the content should allow the display to be updated…
Any ideas ?
