Đây là đoạn code lấy mã chữ và dịch Ram:

void copy_2_ram2(int8 index_char) {

int8 i,j;

for (j=0;j<=5;j++)
{
 for (i=90;i>0;i--)                       // Dich RAM
  buff_disp[i]= buff_disp[i-1];           //Dich RAM sang trai
  buff_disp[0]=font2[index_char].b[j];    //Luu ma ascii vao RAM
  display();                              // Goi hien thi
}
  buff_disp[0]=0xff; // Them mot khoang trang giua hai ky tu
}

void copy_2_ram1(int8 index_char) {
int8 i,j;

for (j=0;j<=5;j++)
{                                      // Dich RAM
