This is an example how to interface to the standard Hitachi-44780 LCD using an 8051 microcontroller and SDCC as C Compiler. I use a standard 16-character by 2-line LCD module, see schematic below. Here, I use 4-bit interfacing.
Schematic: 4-bit interfacing 16x2 LCD
Source Code (For SDCC)
- lcd.h
- test_lcd.c
