You can get the basic LCDInfo driver for this display from here:
Parallel mode: http://www.skippari.net/lcd/alpha/plugi ... driver.dll
Serial mode: http://www.skippari.net/lcd/alpha/plugi ... driver.dll

Here's some information you can use to make the connections:

It's not very extensively tested but it might work

The driver has been developed with the CU20045SCPB-T23A display but it might work with other SCPB-T series displays. If you test it with some other display please report your results here.

Well it sure works
Check out my leet ghetto display stand

is there a spectrum?

I have the driver and the plugin for winamp. When I run LCDinfo all I get is the artist name over and over. Do I need to do something special to get this to work?



Thanks

I assume you know how LCDinfo 0.6 works. I think you should make some screens. If you have an output, it means the display is ok, just edit the screens accordingly.

Okay, maybe I'm just a bit slow.... But how do I install the driver?

I tried last night, by copying the DLL into the LCDInfo directory.... But it didn't seem to have any real effect. What should happen here? I get a new device in the radio-group?

Are you using the 0.6 version of LCDInfo ? Radio group somehow sounds like 0.3 series LCDInfo. In 0.6 the driver should show up in the list of drivers when the dll file is put in the LCDInfo root directory.

Oh, yes, right you are.... I guess I should pay attention when downloading software....

Thank you!

This driver works with my T20A

The only problem I have is that the cursor is not disabled... so I see it all the time moving around the display updating stuff.

According to my info, the T23A and T20A have the same "cursor off" command (16Hex).

Of note is that I found this same problem using LCDHype. But that made the display flicker horribly, lcdinfo is much better in that regard

I wish I could tell you what was causing this, but I don't know. I've wired the module to the serial port, and manually sent the 16Hex command to the module. That worked. It's only with these parallel drivers that it doesn't seem to work.

Let's see, I'm not sure if the driver even sends the command to disable the cursor. Maybe it is disabled by default in the T23A. I need to check this from the driver sources.

Any updates on this? I've read in other forums that the cursor can also be controlled, e.g. special fonts, spectrum etc.

Has anybody gotten characters and not rubbish when using serial input?

Here's an updated version of the T23A driver that has the cursor off command added to the initialization.
http://www.skippari.net/lcd/alpha/plugi ... driver.dll

I have not yet tested it myself so please let us know what happens with it.

Just tried the dll file, no luck getting rid of the curson on the t20a.

Not sure which cursor that is enabled on this VFD,

Underline Cursor On 14H
5x7 Block Cursor On 15H
Cursor Off 16H

...but the d0-d7 instruction 16H should turn of any cursor.

Yes it was the 0x16 command that I added. But I noticed that I forgot to add any delay after the software reset command so I have now put a 100ms delay there. Might help or not but anyway the file is updated.
