Monochrome graphical display system

See Quick Start Guide for the mono graphics service.

This library provides an interface to drawing graphics on monochrome graphical displays

The graphics drivers consists of the following:

The generic drawing primitives is a library of functions for drawing graphics primitives such as lines, rectangles and circles. It uses other functions implemented by the display driver for drawing the primitives. The implementation of these functions can optionally be used by a display driver, but if the hardware of the display allows faster handling of any of the primitives, the display driver can implement it directly.

The display specific drivers provides an interface to the graphical display. It implements the low level communication with the display hardware, putting pixels on the display and drawing primitives such as lines, circles and rectangles. Depending on the display driver implementation, drawing the graphics primitives might be handled by the generic graphics drawing primitives rather than the display driver itself.

Examples

The following examples are available for the driver:

The functions in the library are not interrupt safe.

Modules

 Quick Start Guide(s)
 In this section you can find a list of all Quick Start guides related to the Monochrome graphical display system.
 
 Spinner widget for monochrome graphical displays
 This module provides a spinner widget system for monochrome graphical displays.
 
 GFX Mono Font Library
 This modules provides functionality for outputting a monochrome font to a display.
 
 Generic monochrome graphic primitives
 This is a service providing generic implementations of graphic primitives.
 
 2832HSWEG04 graphic library abstraction
 This module is an abstraction layer between the graphic library and the 2832HSWEG04 monochrome LCD display connected to a SSD1306 LCD controller.
 
 Framebuffer
 This module provides read/write from and to a framebuffer in RAM.
 
 NULL display device
 This module provides empty read/write functions to a null device (framebuffer in RAM), removing the need for an actual display or controller during testing, and enabling the use of most XMEGA boards.
 
 Menu system for monochrome graphical displays
 This module provides a simple menu system for monochrome graphical displays.
