DigiPi ILI9486 Display - too bright/washed out white bkgd

[Frank Cupp]

The menu item screen shows proper however the physical  ILI9486 display 
appears to use very light colors.  Is there a way to make it 'dark' mode or at least look like the menu screen option?

Hi Frank, some of the ili9486 displays have inverted colors, but fear not, there's a
tweak you can make to DigiPi to get the black background,


Click Shell
Password:  raspberry

sudo remount
sudo nano direwatch.py
sudo nano digibanner.py


and put a pound/hash (#) sign in front of the "disp.invert()" like below,


elif displaytype == 'ili9486':
   ## Largest ili9486 display, no buttons
   from spidev import SpiDev
   spi = SpiDev(0,0)
   spi.mode = 0b10  
   spi.max_speed_hz = 48000000
   disp = ili9486.ILI9486(
       spi=spi,
       rst=25,
       dc=24,
       origin=ili9486.Origin.LOWER_RIGHT
   ).begin()
#   disp.invert()


best,

That works.
