Constructor & Destructor Documentation

AdafruitTFTDriver()

AdafruitTFTDriver::AdafruitTFTDriver	(	int	csPin,
		int	dcPin )

Instantiate the Adafruit driver using hardware SPI.

Parameters

csPin	The SPI chip select pin
dcPin	The SPI data/command pin

Member Function Documentation

clearScreen()

void AdafruitTFTDriver::clearScreen ( TFTColor color )

overridevirtual

Assigns one color to all pixels on the screen, clearing any previously drawn text.

Parameters

color

The color to assign.

Implements TFTDriver.

drawText()

void AdafruitTFTDriver::drawText ( TFTPoint topLeft, TFTColor textColor, TFTColor bgColor, const char * string )

overridevirtual

Draws monospace text.

If the text goes off the right edge of the screen, it is wrapped to the next line.

Parameters

topLeft	The top-left position of the first character.
textColor	The text color.
bgColor	The background color.
string	The NUL-terminated ASCII string to draw.

Implements TFTDriver.

encodeColor()

AdafruitTFTDriver::Color565 AdafruitTFTDriver::encodeColor ( TFTColor color )

staticprivate

Converts an abstract color to the representation used by the Adafruit ST7735 library.

getScreenHeight()

unsigned AdafruitTFTDriver::getScreenHeight ( ) const

nodiscardoverridevirtual

Returns the height, in pixels, of the screen.

Implements TFTDriver.

getScreenWidth()

unsigned AdafruitTFTDriver::getScreenWidth ( ) const

nodiscardoverridevirtual

Returns the width, in pixels, of the screen.

Implements TFTDriver.

getTextHeight()

unsigned AdafruitTFTDriver::getTextHeight ( ) const

nodiscardoverridevirtual

Returns the height, in pixels, of one character.

Implements TFTDriver.

getTextWidth()

unsigned AdafruitTFTDriver::getTextWidth ( ) const

nodiscardoverridevirtual

Returns the width, in pixels, of one character.

Implements TFTDriver.

initialize()

void AdafruitTFTDriver::initialize ( )

overridevirtual

Initializes the display.

The display must be initialized before any other functions are called.

Implements TFTDriver.
