Arduino-LiquidCrystal-I2C-library VS ruduino

For the Libary "LiquidCrystal_I2C.h" i use this one https://github.com/fdebrabander/Arduino-LiquidCrystal-I2C-library

What we are going to do is simply try writing a text message to the LCD Display using Rust. In order to do so, we will have to figure out how to link and use the LiquidCrystal-I2C Arduino library in our rust crate. In other words, we would like to do something like this, but in Rust.

Are you sure you installed the correct one? I believe this is what you need

I've discovered that Ruduino has become quite usable in the meantime, so I was able to remove a lot of low-level port writes and unsafe code in favor of their nicely packaged Ruduino equivalents.

Rust language shares all advantages of efficient C++ code. With the rust community growing year after year, more and more people try using rust to program their Arduino boards. Consequently, the Arduino Rust ecosystem have significantly developed in the last couple of years. The Hardware Abstraction Layer for AVR microcontrollers avr-hal, Rudino library and ravedude CLI utility to make Rust development for AVR microcontrollers easier are just a few examples of the solid foundation developed so far.

It already works on Arduino. You can use https://github.com/avr-rust/avrd for register level access akin to AVR-GCC or https://github.com/avr-rust/ruduino a little bit higher level access. If you want high level "safe" interfaces you can use: https://github.com/Rahix/avr-hal
