Definition at line 5 of file DisplayInterface.cpp.

clear()

virtual void clear ( )

pure virtual

Clear the frame buffer or clear the display.

Implemented in SSD1306_DisplayInterface.

drawBackground()

virtual void drawBackground ( )

inlinevirtual

Draw a custom background.

Reimplemented in SSD1306_DisplayInterface.

Definition at line 29 of file DisplayInterface.hpp.

display()

drawPixel()

virtual void drawPixel ( int16_t x, int16_t y, uint16_t color )

pure virtual

Paint a single pixel with the given color.

Implemented in SSD1306_DisplayInterface.

setTextColor()

virtual void setTextColor ( uint16_t color )

pure virtual

Set the text color.

Implemented in SSD1306_DisplayInterface.

setTextSize()

virtual void setTextSize ( uint8_t size )

pure virtual

Set the text size.

Implemented in SSD1306_DisplayInterface.

setCursor()

virtual void setCursor ( int16_t x, int16_t y )

pure virtual

Set the cursor position.

Implemented in SSD1306_DisplayInterface.

write()

size_t write ( uint8_t c )

overridepure virtual

Write a character to the display.
