# Initialize the lcd screen.
# Note: A DAC or a PWM backlight controller can be used to control the
# backlight intensity if supported:
#  lcd = display.SPIDisplay(backlight=display.DACBacklight(channel=2))
#  lcd.backlight(25) # 25% intensity
# Otherwise the default GPIO (on/off) controller is used.
#  OpenMV Cam M4/M7/H7/H7 Plus -> DAC and GPIO Support
