Berikut ini adalah contoh program untuk melakukan proses init menggunakan C:
#define LCD_data P2
#define LCD_D7
P2_7
#define LCD_rs
P1_0
#define LCD_rw
P1_1
#define LCD_en
P1_2
void LCD_init()
{
LCD_data = 0x38;
//Function set: 2 line, 8-bit,
5x7 dots
LCD_rs
= 0;
//Selected command register
LCD_rw
= 0;
//We are writing in data
