// Size of the LCD in pixels
#define R2D_WIDTH 175
#define R2D_HEIGHT 220

// Dithering ON/OFF

#define R2D_DITHERING R2D_OFF

// Kind of display
#define R2D_LCD_DISPLAY R2D_COLOR

// Refresh mode of LCD
#define R2D_REFRESH R2D_HORIZONTAL

// Mirrorred mode
//#define R2D_MIRRORED_X
//#define R2D_MIRRORED_Y

// ln2 of the number of bits to code a pixel value
// (color depth)
//#define R2D_PIXEL_DEPTH 32 // 8 for alpha channel 
#define R2D_PIXEL_DEPTH 16 // No alpha channel

// ln2 of previous value
#define R2D_PIXEL_POS_TO_BIT_POS 4



// ln2 of the number of pixels in one memory word
// (Number of pixels MUST BE A POWER OF TWO 
// for optimization reasons since to compute the address of a pixel
// in memory one would like to avoid division and would prefer
// to use shifts)
// 2^0 = 1 pixel
