NOTE: Some LCD drivers implement an internal framebuffer for efficiency reasons but do not export a framebuffer interface. So those LCD cannot be used as framebuffer drivers.

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.

If not, then it will have the following limitations: Reading graphics memory cannot be supported, and All pixel writes must be aligned to byte boundaries. The latter limitation effectively reduces the 128x96 display to 64x96. NOTE: This option should not be used if CONFIG_LCD_FRAMBEBUFFER is enabled. That options provides for a more generalized, external LCD framebuffer. This internal framebuffer support should not be enabled with CONFIG_LCD_FRAMBEBUFFER because this external common framebuffer interface will provide the necessary buffering. endif # LCD_P14201 config LCD_MAX7219 bool "Matrix of 8x8 LEDs controlled by MAX7219" default n ---help--- Matrix of LEDs (8x8) controlled by MAX7219.
