Classes
class	Adafruit_SPITFT
	Adafruit_SPITFT is an intermediary class between Adafruit_GFX and various hardware-specific subclasses for different displays. It handles certain operations that are common to a range of displays (address window, area fills, etc.). Originally these were all color TFT displays interfaced via SPI, but it's since expanded to include color OLEDs and parallel-interfaced TFTs. THE NAME HAS BEEN KEPT TO AVOID BREAKING A LOT OF SUBCLASSES AND EXAMPLE CODE. Many of the class member functions similarly live on with names that don't necessarily accurately describe what they're doing, again to avoid breaking a lot of other code. If in doubt, read the comments. More...

Macros
#define	DEFAULT_SPI_FREQ   16000000L

Typedefs
typedef uint32_t	ADAGFX_PORT_t
	PORT values are 32-bit.
typedef volatile ADAGFX_PORT_t *	PORTreg_t
	PORT register type.

Enumerations
enum	tftBusWidth { tft8bitbus, tft16bitbus }

Detailed Description

Part of Adafruit's GFX graphics library. Originally this class was written to handle a range of color TFT displays connected via SPI, but over time this library and some display-specific subclasses have mutated to include some color OLEDs as well as parallel-interfaced displays. The name's been kept for the sake of older code.
