APLIKASI ATMEGA16 UNTUK LCD

Berikut adalah cara membuat sample rangkaian dan program untuk LCD 16×2 menggunakan IC ATMega16.

Program yang digunakan:
1. Proteus ISIS 7
2. MikroC for AVR

Komponen yang digunakan dalam rangakaian:
1. IC ATMega16
2. Potensiometer
3. LCD 16×2
4. Crystal

Rangkaian seperti gambar diatas, sedangkan programnya ada di bawah ini:

sbit LCD_RS at PORTB.B2;
sbit LCD_EN at PORTB.B3;
sbit LCD_D4 at PORTB.B4;
sbit LCD_D5 at PORTB.B5;
sbit LCD_D6 at PORTB.B6;
sbit LCD_D7 at PORTB.B7;

sbit LCD_RS_Direction at DDRB.B2;
sbit LCD_EN_Direction at DDRB.B3;
sbit LCD_D4_Direction at DDRB.B4;
sbit LCD_D5_Direction at DDRB.B5;
sbit LCD_D6_Direction at DDRB.B6;
sbit LCD_D7_Direction at DDRB.B7;

Move_Delay();
}

for(i=0; i<7; i++) {
Lcd_Cmd(LCD_SHIFT_RIGHT);
