API Reference LcdDisplay v0.0.4

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.

Defines a behaviour required for an LCD driver.

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

Knows how to commuticate with HD44780 type display via GPIO pins. Currently supports the 4-bit mode only.

Knows how to commuticate with HD44780 type display via I2C.

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