Public Member Functions
	UIDisplayDevice (size_t width, size_t height, FramebufferFormat format=FramebufferFormat::MONO_VLSB, StructFramebufferText txt_cnf={.font=font_8x8})
	Construct a new UIDisplayDevice object.

virtual	~UIDisplayDevice ()
	Destroy the UIDisplayDevice object.

virtual void	show ()=0
	This is an pure virtual member function that all final derived class must implement. It transfers the framebuffer buffer to the entire display screen buffer.

virtual void	show (Framebuffer *frame, uint8_t anchor_x, uint8_t anchor_y)=0
	This is an pure virtual member function that all final derived class must implement. It transfers the framebuffer buffer to the a part of display screen buffer starting at the (anchor_x, anchor_y) coordinates of the screen , expressed in pixel.

Detailed Description

This is the abstract class to handle all generic behavior of physical display devices (e.g. OLED screen SSD1306). It derived from Framebuffer. This allows to draw text and graphics directly into the display framebuffer thanks to Framebuffet class text and graphic primitives.

Constructor & Destructor Documentation

◆ UIDisplayDevice()

UIDisplayDevice::UIDisplayDevice	(	size_t	width,
		size_t	height,
