Libraries and sample program/utilities to send text to HD44780 LCD displays, written in a variety of languages: C, CPP, GO, RUST, Python and Bash.

I wrote this software avoiding useless dependencies: you need only the compiler in most cases. Only Mash requires i2c tools.

It's tested using this/these distributions of Linux:

• Ubuntu 18.04.1 LTS
• RaspberryOs (Debian GNU/Linux 11 (bullseye) ARM)

using, as compiler, one in this list:

• clang version 6.0.0-1ubuntu2 aarch64-unknown-linux-gnu
• g++ (Debian 10.2.1-6) 10.2.1 20210110
• go1.10.4 linux/arm64
• rustc 1.39.0

and with :

• Python 3.6.9
• Python 3.9.2
• Bash 4.4.20(1)-release (aarch64-unknown-linux-gnu)

I tested this software on:

• NVidia Jetson Nano, using a 4 lines LCD display. Is required a board with GPIO/I2C.
• Raspberry Pi 400 Rev 1.1 I have other hardware to test: I'll add information here asap.

C/CPP version are the classic autotool setting, in Rust and Go a simple Makefile is available, with the classic directives (all, install , etc)

All compiled version have an installable man page. All the tools have a -h flag showing command line options.

• print the string 'Ip: 192.168.0.1' on row 1 (C version):
  simple_lcd -r1 -t 'Ip: 192.168.0.1'

• Same example, using Rust version:
  simple_lcd_r -r1 -t'ethernet:'
