  • Device Interface. NX supports any graphics device either of two device interfaces:
    1. Any device with random accesss video memory using the NuttX framebuffer driver interface (see include/nuttx/video/fb.h).
    2. Any LCD-like device than can accept raster line runs through a parallel or serial interface (see include/nuttx/lcd/lcd.h). By default, NX is configured to use the frame buffer driver unless CONFIG_NX_LCDDRIVER is defined =y in your NuttX configuration file.
