Detailed Description

+

Basic routines for interfacing a HD44780U-based character LCD display.

+
#include <lcd.h>
+

LCD character displays can be found in many devices, like espresso machines, laser printers. The Hitachi HD44780 controller and its compatible controllers like Samsung KS0066U have become an industry standard for these types of displays.

+

This library allows easy interfacing with a HD44780 compatible display and can be operated in memory mapped mode (LCD_IO_MODE defined as 0 in the include file lcd.h.) or in 4-bit IO port mode (LCD_IO_MODE defined as 1). 8-bit IO port mode is not supported.

+

Memory mapped mode is compatible with old Kanda STK200 starter kit, but also supports generation of R/W signal through A8 address line.

+

+Definition for LCD controller type

Use 0 for HD44780 controller, change to 1 for displays with KS0073 controller.

+
#define LCD_CONTROLLER_KS0073   0
 
+ + + + + + + + + + + + + + + + + + +

+Definitions for Display Size

Change these definitions to adapt setting to your display

+

These definitions can be defined in a separate include file lcd_definitions.h instead modifying this file by adding -D_LCD_DEFINITIONS_FILE to the CDEFS section in the Makefile. All definitions added to the file lcd_definitions.h will override the default definitions from lcd.h

+
#define LCD_LINES   2
 
#define LCD_DISP_LENGTH   16
 
#define LCD_LINE_LENGTH   0x40
 
#define LCD_START_LINE1   0x00
 
#define LCD_START_LINE2   0x40
 
#define LCD_START_LINE3   0x14
 
#define LCD_START_LINE4   0x54
 
#define LCD_WRAP_LINES   0
 
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+Definitions for 4-bit IO mode

The four LCD data lines and the three control lines RS, RW, E can be on the same port or on different ports. Change LCD_RS_PORT, LCD_RW_PORT, LCD_E_PORT if you want the control lines on different ports.

+

Normally the four data lines should be mapped to bit 0..3 on one port, but it is possible to connect these data lines in different order or even on different ports by adapting the LCD_DATAx_PORT and LCD_DATAx_PIN definitions.

+

Adjust these definitions to your target.
+ These definitions can be defined in a separate include file lcd_definitions.h instead modifying this file by adding -D_LCD_DEFINITIONS_FILE to the CDEFS section in the Makefile. All definitions added to the file lcd_definitions.h will override the default definitions from lcd.h

+
#define LCD_IO_MODE   1
 
#define LCD_PORT   PORTA
 
#define LCD_DATA0_PORT   LCD_PORT
 
#define LCD_DATA1_PORT   LCD_PORT
 
#define LCD_DATA2_PORT   LCD_PORT
 
#define LCD_DATA3_PORT   LCD_PORT
 
#define LCD_DATA0_PIN   0
 
#define LCD_DATA1_PIN   1

+Definitions of delays

Used to calculate delay timers. Adapt the F_CPU define in the Makefile to the clock frequency in Hz of your target

+

These delay times can be adjusted, if some displays require different delays.
+ These definitions can be defined in a separate include file lcd_definitions.h instead modifying this file by adding -D_LCD_DEFINITIONS_FILE to the CDEFS section in the Makefile. All definitions added to the file lcd_definitions.h will override the default definitions from lcd.h
