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.
