Project - AV2040 Library (HD44780 compatible LCD display)

AV2040 Library (HD44780 compatible LCD display)

Small library that is heavily based on GHI’s HD44780 module code. The AV2040 module code is tested to work with a Avision AV 2040 (4*20 ) LCD display and supports displaying / hiding different cursor types. The GHI electronic driver does not support displaying the cursor and setting the cursor position works not correctly for the 3rd and 4th line.

I have added a small example program, that demonstrate the usage for a AV2040 that is hooked up to a gadgeteer connector.

Physically the LCD display is soldered to GHI electronics’ HD44780 module (Part No. HD447-GM-358) as shown in the attached pictures.
