Mikroelektronika MIKROE-350 Fiche De Données

The mikroBasic PRO for AVR provides a library for communication with Lcds (with
HD44780 compliant controllers) through the 4-bit interface. An example of Lcd con-
nections is given on the schematic at the bottom of this page.

For creating a set of custom Lcd characters use Lcd Custom Character Tool.
