API Reference LcdDisplay v0.0.9

Modules

LcdDisplay is a simple Elixir library that allows you to control an Liquid-crystal display (LCD) like Hitachi HD44780.

Defines a behaviour required for GPIO abstraction.

Defines a behaviour required for I²C abstraction.

Wraps a given display driver and controls the display using that driver.

Defines a behaviour required for an LCD driver.

Supervises display controller processes.

Lets you control GPIOs. A thin wrapper of elixir-circuits/circuits_gpio.

Knows how to commuticate with HD44780 type display via GPIO pins. Supports the 4-bit mode only. You can turn on/off only one backlight LED.

Knows how to commuticate with HD44780 type display via I2C. You can turn on/off only one backlight LED.

Lets you communicate with hardware devices using the I2C protocol. A thin wrapper of elixir-circuits/circuits_i2c.
