Keyboard library for Arduino for all languages and keys mapping

This library allows an Arduino board with USB functions to act as a keyboard. The following languages are integrated: English, German, Russian, French, Greek, Hebrew, Italian, Georgian

This library library works like this: you connect a language file and from the moment you can send texts in this language to the computer via HID keyboard emulation. The language file contains all utf-8 characters of the respective language. The position of the characters corresponds to the HID scancode of the keys. Your text is decomposed into individual characters and for each character the scan code is found in the language file, after which the scan code is sent to the computer. The language file can be generated automatically. So almost every language can be recorded.

Restriction in use

The principle of the library does not allow printing of characters that are generated by successive pressing of two keys.
