Implemented in daisy::OledColorDisplay< DisplayDriver >.

◆ GetBounds()

Rectangle daisy::ColorGraphicsDisplay::GetBounds ( ) const

inline

◆ Height()

virtual uint16_t daisy::ColorGraphicsDisplay::Height ( ) const

pure virtual

Implemented in daisy::OledColorDisplay< DisplayDriver >.

Implemented in daisy::OledColorDisplay< DisplayDriver >.

◆ SetCursor()

void daisy::ColorGraphicsDisplay::SetCursor	(	uint16_t	x,
		uint16_t	y
	)

inline

Moves the 'Cursor' position used for WriteChar, and WriteStr to the specified coordinate.

Parameters

x	x pos
y	y pos

◆ Update()

virtual void daisy::ColorGraphicsDisplay::Update ( )

pure virtual

Writes the current display buffer to the OLED device using SPI or I2C depending on how the object was initialized.

Implemented in daisy::OledColorDisplay< DisplayDriver >.

◆ Width()

virtual uint16_t daisy::ColorGraphicsDisplay::Width ( ) const

pure virtual

Implemented in daisy::OledColorDisplay< DisplayDriver >.

◆ WriteChar()

virtual char daisy::ColorGraphicsDisplay::WriteChar	(	char	ch,
		FontDef	font,
		bool	on
	)

pure virtual

Writes the character with the specific FontDef to the display buffer at the current Cursor position.

Parameters

ch	character to be written
font	font to be written in
on	on or off

Returns: &

Implemented in daisy::ColorGraphicsDisplayImpl< ChildType >, and daisy::ColorGraphicsDisplayImpl< OledColorDisplay< DisplayDriver > >.

◆ WriteString()

virtual char daisy::ColorGraphicsDisplay::WriteString	(	const char *	str,
		FontDef	font,
		bool	on
	)

pure virtual

Similar to WriteChar, except it will handle an entire String. Wrapping does not happen automatically, so the width of the string must be kept within the dimensions of the screen.

Parameters

str	string to be written
font	font to use
on	on or off

Returns: &

Implemented in daisy::ColorGraphicsDisplayImpl< ChildType >, and daisy::ColorGraphicsDisplayImpl< OledColorDisplay< DisplayDriver > >.

	)

pure virtual

Similar to WriteString but justified within a bounding box.

Parameters

str	string to be written
font	font to use
boundingBox	the bounding box to draw the text in
alignment	the alignment to use
on	on or off

Returns: The rectangle that was drawn to

Implemented in daisy::ColorGraphicsDisplayImpl< ChildType >, and daisy::ColorGraphicsDisplayImpl< OledColorDisplay< DisplayDriver > >.
