Nova-Matic LED Display

[andykoa]

Hi there,
Iam quite new and I have a problem with a Nova-Matic LED Display.

The LED Matrix has 7x59 LEDs.
What would be the Resolution?

Anyone also knows this Display?

Found out a lot -
but I need to send Hex Code "1B" before the Text and HEX Code "05" after the Text.
Can anyone tell me how?
Please?

Have you got LCD Smartie controlling the display? I don't know about these displays but if they use a serial port then you can probably use the "Test Driver" display plugin in Smartie. Just select Test Driver in the display plugin configuration window. You can try forcing Smartie to send the 0x1B and 0x05 codes with the $Chr(27) and $Chr(5) commands in a screen, for example:

Code: Select all

$Chr(27)Display Test$Chr(5)

Hey, this helps a little ...
I got the Text scrolling, but it seems that the testdriver doesnt know how big the display is ...
I am really a newbie and I had some problems to understand what really should be written in the ini File.

Hey, I found out that if you use more that 10 Characters the Text is cutted - is there a possibilty to insert more by changing something in the ini File?

It sounds like your display is 1 line of 10 characters (7x59 LEDs would give that). You can try setting LCD Smartie to use a display of 1x16 (look on the Screen tab of the display settings) so that Smartie will allow you to send the start char $Chr(27), then the text (make sure it's not more than 10 chars) plus the terminator $Chr(5). The 1x10 display size won't work properly because Smartie treats the start and terminator characters as part of the displayed text so you'd only be allowed 8 useful text characters.

Using 1x16 size means that you probably can't use the clever scrolling etc that Smartie can do to show more text on a small display. It will allow you to write more characters than the display can show - depending on how the display unit works, it might scroll, or simply cut off the end of your text.

Because your display is simple to control, you probbaly don't need anything in the test driver INI file at all. There is no initialisation, no commands to jump to the next line...

If you are into programming (C++/C#/Delphi) you can try writing a simple driver plugin for this display. You should be able to use one of the open-source driver plugins posted on this forum as a starting point. The driver itself inserts the required start and terminator commands, so you can take advantage of Smartie's 1x10 display mode and use its scrolling etc.
