-config LCD_NOGETRUN
- bool "Write-only LCD"
- default n
- ---help---
- Many LCD hardware interfaces provide only minimal graphics capability. In
- particulary, many simple LCD interfaces are write only. That is we, can
- write graphics data to the LCD device memory, but we cannot read it back.
- If the LCD hardware does not support reading the graphics memory, then
- this option should be defined so that the NX layer can taking alternative
- measures when the LCD is not readable. For example, if the LCD is not
- readable, then NX will not attempt to support transparency.
-
- See also NX_WRITEONLY in the graphics support menu.

- The brighter the screen, the hight the power usage.
-
- On LCDs that have a backlight, this value corresponds directly to that
- backlight setting. Board-specific logic may place restrictions on this
- value.
