David,
     Sure. Here is the cmd and the data routines:
                             extern void LCD_Send_cmd(unsigned char value)
                                 {
                                         LCD_data =3D value;
                                         LCD_rs =3D 0;
                                         LCD_rw =3D 0;
                                         LCD_e =3D 1;
                                         wait_ms(30);
                                         LCD_e =3D 0;
                                 }

                            extern void LCD_Send_data(unsigned char value)
                                 {
                                         LCD_data =3D value;
                                         LCD_rs =3D 1;
                                         LCD_rw =3D 0;
                                         LCD_e =3D 1;
                                         wait_ms(30);
                                         LCD_e =3D 0;
                                 }
     You call them for sending either cmds or data to the LCD. The=20
initialize routine uses the cmd routine. Feel free to ask whatever=20
questions you think are necessary. I appreciate the help!
Thanks,
rich!
