Crate clerk

Clerk

Clerk is a generic and hardware agnostic libary to controll HD44780 compliant LCD displays. Its main goal is to provide all features defined in the HD44780 spec.

Structs

• DataPins4Lines
  Four data lines pin wiring setup.
• DataPins8Lines
  Eight data lines pin wiring setup.
• Display
  A HD44780 compliant display.
• DisplayControlBuilder
  A struct for creating display control settings.
• EntryModeBuilder
  A struct for creating display entry mode settings.
• FunctionSetBuilder
  A struct for creating display function settings.
• ParallelConnection
  The parallel connection mode is the most common wiring mode for HD44780 compliant displays. It can be used with either four (DataPins4Lines) or eight (DataPins8Lines) data lines.
• Pins
  This struct is used for easily setting up ParallelConnections.

Enums

• CursorBlinking
  Sets cursor blinking.
• CursorState
  State of a cursor.
• DefaultLines
  Enumeration of default lines.
• Direction
  Enumeration of possible data directions of a pin.
• DisplayState
  State of a display.
• Level
  Enumeration of possible levels of a pin.
• LineNumber
  Enumeration to set display line number.
• ReadMode
  Enumeration possible read operations.
• SeekFrom
  Enumeration of possible methods to seek within a Display object.
• ShiftTo
  Enumeration of possible methods to shift a cursor or display.
• WriteMode
  Enumeration possible write operations.

Traits

• Delay
  The Delay trait is used to adapt the timing to the specific hardware and must be implemented by the libary user.
• DisplayHardwareLayer
  The DisplayHardwareLayer trait is intended to be implemented by the library user as a thin wrapper around the hardware specific system calls.
• Home
  This trait is used to specify the start address of the display data RAM.
• Init
  This trait is used to provide an initialization implementation for a [Display] connection. [Display]: struct.Display.html
• Receive
  This trait is used to provide an implementation for receiving data via a [Display] connection. [Display]: struct.Display.html
• Send
  This trait is used to provide an implementation for sending data via a [Display] connection. [Display]: struct.Display.html
