I was curious if anyone has ran across this LCD and if they have gotten it to work with LCD Smartie? The LCD powers on fine, just have not had much luck in getting a driver to display anything. Any help would be appreciated!!

This forum posting talks about the exact LCD:

Since this module contains an μC for interfacing singals, I can't be sure.
this post contains some info about the pinouts but you have to make test and try to make it work http://www.lcdstudio.com/forum/viewtopi ... 2c30aa3b7a

Good luck

I've just got one of theese displays working. The pinout in the mentioned lcd list is correct. power is 5V. The display is from a NCR pole display from their POS systems. The interface is serial (9600 8N1) speed can be changed. I've got a pdf for the commands from NCR. search their site for" ncr 5972 user's manual" or such. Or let me upload it. Basically you power it up and and send it hex: 1B05 and then it accepcts aschii codes. A character selftest is hex:1B04 which scrolls through the character rom. Line shift, scroll etc. are different from the crystalfonts displays som there has to be made a macro anyone up to that? Or can someone tell me how you make one for smartie lcd?

Cheers

Smartie's "test driver" allows you to interface to practically any LCD that you can send bytes to over a serial port, by defining the commands to send to the display for various things like "clear display" and "go to character position x,y". See http://lcdsmartie.sourceforge.net/testdriver.html There are various posts on this forum about using this test driver.
