This is an implementation of a hardware driver for a HD44780 type LCD controller write in Rust which uses the linux-embedded-hal library. It exposes a simple trait-based API for the command set which minimizes the coupling between the hardware driver (GPIO, I2C, etc) and the code that passes commands and data to the display.
You will need to have a recent version of Rust installed. Any version of Rust that supports version 0.2 of the Linux embedded hal should work but versions from 1.39 to 1.45 of Rust have been used during initial development on both the nightly and release channels. Earlier versions might work as well but have not been tested.
Development can be done on an OS (GPIO, I2C, etc) that Rust supports but the expected target would typically be something like a Raspberry Pi, STM32, or another embeddable system which can run Linux. All initial development has been done with a combination of a laptop running Windows 10 and a 4GB Raspberry Pi 4 running the Raspberry Pi OS (Raspbian).
To use the crate in your own project all you need to do is include it in
[dependencies] of you project's Cargo.toml file like you would any other
crate.
