LCD MODULE: To display an interactive messages we are using LCD Module. We examine an intelligent LCD display of two lines, 20 characters per line, that is interfaced to the 8051.The protocol (handshaking) for the display is as shown. Where as D 0 to D 7th bit is the Data lines, RS, RW and EN pins are the control pins and remaining pins are +5V, -5V and GND to provide supply. Where RS is the Register Select, RW is the Read Write and EN is the Enable pin. The display contains two internal byte-wide registers, one for commands (RS=0) and the second for characters to be displayed (RS=1). It also contains a user-programmed RAM area (the character RAM) that can be programmed to generate any desired character that can be formed using a dot matrix. To distinguish between these two data areas, the hex command byte 80 will be used to signify that the display RAM address 00h will be chosen. Port1 is used to furnish the command or data type, and ports 3.2 to3.4 furnish register select and read/write levels.
