//! SSD1675 ePaper Display Driver
//!
//! For a complete example see
//! [the Raspberry Pi Inky pHAT example](https://github.com/wezm/ssd1675/blob/master/examples/raspberry_pi_inky_phat.rs).
//!
//! ### Usage
//!
//! To control a display you will need:
//!
//! * An [Interface] to the controller
//! * A [display configuration][Config]
//! * A [Display]
//!
//! The [Interface] captures the details of the hardware connection to the SSD1675 controller. This
//! includes an SPI device and some GPIO pins. The SSD1675 can control many different displays that
//! vary in dimensions, rotation, and driving characteristics. The [Config] captures these details.
//! To aid in constructing the [Config] there is a [Builder] interface. Finally when you have an
//! interface and a [Config] a [Display] instance can be created.
//!
//! Optionally the [Display] can be promoted to a [GraphicDisplay], which allows it to use the
//! functionality from the [embedded-graphics crate][embedded-graphics]. The plain display only
//! provides the ability to update the display by passing black/white and red buffers.
//!
//! To update the display you will typically follow this flow:
//!
//! 1. [reset](display/struct.Display.html#method.reset)
//! 1. [clear](graphics/struct.GraphicDisplay.html#method.clear)
//! 1. [update](graphics/struct.GraphicDisplay.html#method.update)
//! 1. [sleep](display/struct.Display.html#method.deep_sleep)
//!

//! [Display]: display/struct.Display.html
//! [GraphicDisplay]: display/struct.GraphicDisplay.html
//! [Config]: config/struct.Config.html
