3. If the OLED1 module is connected to the SAM4L Xplained Pro, then
support for the OLED display can be enabled by making the following
changes to the configuration:
System Type -> Peripherals:
CONFIG_SAM34_SPI=y : Enable the SAM4L SPI peripheral
Device Drivers -> SPI
CONFIG_SPI=y : Enable SPI support
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
CONFIG_SPI_CMDDATA=y : CMD/DATA support is required
CONFIG_SPI_OWNBUS=y : Smaller code if this is the only SPI device
Device Drivers -> LCDs
CONFIG_LCD=y : Enable LCD support
CONFIG_LCD_MAXCONTRAST=255 : Maximum contrast value
CONFIG_LCD_UG2832HSWEG04=y : Enable support for the OLED
CONFIG_LCD_SSD1306_SPIMODE=0 : SPI Mode 0
CONFIG_LCD_SSD1306_SPIMODE=3500000 : Pick an SPI frequency
Board Selection -> SAM4L Xplained Pro Modules
CONFIG_SAM4L_XPLAINED_OLED1MODULE=y : OLED1 module is connected
CONFIG_SAM4L_XPLAINED_OLED1MODULE_EXT1=y : In EXT1, or EXT2
CONFIG_SAM4L_XPLAINED_OLED1MODULE_EXT2=y
The NX graphics subsystem also needs to be configured:
CONFIG_NX=y : Enable graphics support
CONFIG_NX_LCDDRIVER=y : Using an LCD driver
CONFIG_NX_NPLANES=1 : With a single color plane
CONFIG_NX_WRITEONLY=y : This is a write only LCD
CONFIG_NX_DISABLE_2BPP=y : Disable all resolutions except 1BPP
CONFIG_NX_DISABLE_4BPP=y
CONFIG_NX_DISABLE_8BPP=y
CONFIG_NX_DISABLE_16BPP=y
CONFIG_NX_DISABLE_24BPP=y
CONFIG_NX_DISABLE_32BPP=y
CONFIG_NX_PACKEDMSFIRST=y
CONFIG_NXTK_BORDERWIDTH=2 : Use a small border
CONFIG_NXTK_DEFAULT_BORDERCOLORS=y : Default border colors
CONFIG_NXFONTS_CHARBITS=7 : 7-bit fonts
CONFIG_NXFONT_SANS17X23B=y : Pick a font (any that will fit)
Then, in order to use the OLED, you will need to build some kind of
graphics application or use one of the NuttX graphics examples.
Here, for example, is the setup for the graphic "Hello, World!"
example:
CONFIG_EXAMPLES_NXHELLO=y : Enables the example
CONFIG_EXAMPLES_NXHELLO_DEFAULT_COLORS=y : Use default colors (monochrome)
CONFIG_EXAMPLES_NXHELLO_DEFAULT_FONT=y : Use the default font
CONFIG_EXAMPLES_NXHELLO_BPP=1 : One bit per pixel
CONFIG_EXAMPLES_NXHELLO_EXTERNINIT=y : Special initialization is required.

support for the SLCDt can be enabled by making the following
