not sure it is a hd44780 controlled lcd

hey,
I bought an lcd but I can't find the exact datasheet.
It is a PC-2002D7-2.

Also it is delivered with an lcd message controller, this is an RS232 to lcd display module. Is this necessary to install, because I've seen the lcd is generally conected to the parallel port.

Do you have any pinout ids or something?

Can you provide more info about the manufacturer?

If it has a serial port interface then it shouldn't matter what the controller chip is.

Sounds like my recent post about the GameOptics display i bought. I was able to work out the commands that were being sent to it and drive it with the test driver.

Did it come with any data on the command set for the display? Is there software with it?

If there is software it should be possible to examine whats happening on the com port

hy, sorry I couldn't reply earlier.
I was able to find the datasheet on internet.
It can be downloaded here:
http://uk.farnell.com/jsp/endecaSearch/ ... search&y=0

The way I see it only 3 pins of the serial port interface are used (ground, power feed, and 1 for data).

I hope this can be linkt with my pc.

well according to that data, assuming ive interpreted the control codes correctly, you should open the config.ini in notepad and add this:

Code: Select all

[Test Driver]
Init=1
Fini=1
GotoLine1=3,0,0
GotoLine2=4,0,0

and you also need to set the line

Code: Select all

LCDType=5

in the [General Settings] section of the ini file

sorry, the only file I found was config.cfg.
Or is this this file?

If I open this file I see all the configurations made in smartie.

I also found the manufacturer of the lcd: " all shore ".
This is the datasheet of the lcd :

Wouldn't it be easier to just connect the lcd with the parallel port of my pc?

For sure you can connect your LCD to parallel port !
circuits can be found here
http://lcdsmartie.sourceforge.net/circuits.htm

But you have a serial interface in your hands! (

)
and its worth to try to make it work with serial port!

The controller you have is a serial to parallel interface that is not officially supported by LCD smartie. However you can ask some documentation by BLUEBIRD ELECTRONICS about interfacing with it

Another try is to play with the Test driver using the the serial interface!

DON"T GIVE UP

The config.ini is located on LCD Smartie folder!

ok, found it.
I was working with an older version of smartie.

Thank you for the help, it is most usefull!
I'll try working with the test driver first.

hey,
I just received an email of elgar electronics:

The Controller takes standard RS232 at the baud rate selected. Ensure you have handshaking off on toyr host system. Other than that you can just send ascii characters after powering up.
