: Buy a 20x2 LCD alphanumeric display with 8 bit controller interface
: and connect it as described below to your LPT1 port.
: LPT pin: LCD pin:
: GND 1 (GND)
: Use external 5V 2 (+5V)
: GND 3 (GND Contrast should be connected to variable resistor, but this works for me!)
: 17 4 Register select
: GND 5 Read/Write
: 1 6 Enable
: 2 7 (D0)
: 3 8 (D1)
: 4 9 (D2)
: 5 10 (D3)
: 6 11 (D4)
: 7 12 (D5)
: 8 13 (D6)
: 9 14 (D7)
: Use external 5V 15 (LED backlight anode +) Don't forget to limit the current
: trough the LED as it might get damaged otherwise.
: (Most backlight LEDs require a 5 Ohm resistor.)
: GND 16 (LED backlight cathode -)
: Have a nice day
