F_CPU is the microcontroller frequency value for the delay.h header file. Default value of F_CPU in delay.h header file is 1000000(1MHz)*/ #include<util/delay.h> /*Includes delay.h header file which defines two functions, _delay_ms (millisecond delay) and _delay_us (microsecond delay)*/ #define LCD_DATA_PORT PORTB /*Defines a macro for the lcd.h header File. LCD_DATA_PORT is the microcontroller PORT Register to which the data pins of the LCD are connected*/ #define LCD_CONT_PORT PORTD /*Defines a macro for the lcd.h header File. LCD_CONT_PORT is the microcontroller PIN Register to which the control pins of the LCD are connected*/ #define LCD_RS PD0 /*Defines a macro for the lcd.h header file. LCD_RS is the microcontroller Port pin to which the RS pin of the LCD is connected*/ #define LCD_RW PD1 /*Defines a macro for the lcd.h header file. LCD_RW is the microcontroller Port pin to which the RW pin of the LCD is connected*/ #define LCD_EN PD2 /*Defines a macro for the lcd.h header file. LCD_EN is the microcontroller Port pin to which the EN pin of the LCD is connected*/ #include<avr/lcd.h> /*Includes lcd.h header file which defines all the functions for all Alphanumeric LCD*/ 4
