AT89S51-HD44780-4BITS by mpeschke

Demonstration of a connection between a HITACHI 44780 LCD Controller module and an Atmel AT89S51 MCU. Code available at https://github.com/mpeschke/hd44780_for_sdcc_51 Although the 8-bit multiplexer and EEPROM chips show on the project's picture, notice that this circuit is using the MCU's internal flash (EA=Vcc).
