this is a guess, but maybe its hd74480 compatible, if so just try wiring it normal way, whats the worst that can happen ^^

Unlikely as it has no LCD controller onboard, so basically useless. Find some cheap one with HD44780 controller, that'll work for sure.

You can only use the 8bit mode! (look at Datasheet "HD44102CH")

Thanks for your reply. I have still some questions to make you, the pins of the lcd the numbers are equivalent where order of the right for the left or the left for the right? how I bind this? to the printer handle? what programs use?

Look at the first Picture, Pin 1 is on the rightside (where the little 1 is).

I don't know to conect to the Lpt, ich dosen't use it with PC.

is impossible to make it work in one PC? i want to display temperatures and info's of my pc... thanks por your reply

It's not impossible. but you can't use the 4Bit-mode, so you need a interface circuit.
The easiest way is to use somethig like LCDprog and an cheap HD74480.

Why is it impossible to use it at 8 bit through the parallel port?
You can connect only one display of those kind but it is possible.
Concerning the HD44780, I'm currently using a 8x2 HD44780 set at 8 bit through the parallel port.
And more...I'm going to use the parallel port to drive 3 LCD HD44780 at 8 bit !

Regards,

Bob

How do you conect 8 Datalines and the 6 controllines to the LPT?
Author:  washburn_it [ Thu Jan 04, 2007 20:29 ]
Post subject: 
The parallel port gives you 12 pins to drive a LCD display: 8 for data lines, 4 for control pins.

DB0-DB7 ---> parallel port data lines (2 to 9 of the parallel port)
CS1,CS2 ---> pin 1,14 of the parallel port
EN ---> pin 16 of the parallel port
R/W ---> to GND (you can only send data but not read from the display)
D/I ---> pin 17 of the parallel port

Reset ---> can be driven individually by a button

Remarks: pin 1,14,17 are active low, pin 16 is active high.

The pin D/I actually I don't know what is its function but if it's a control pin for the display can be driven by the parallel port.

Regards,

Bob
