Hi there,

I want to send data to this LED board: http://www.conrad.de/ce/de/product/590998/LED-LAUFSCHRIFT-ROT
The data sheet is available here: http://www.produktinfo.conrad.com/datenblaetter/575000-599999/590998-da-01-en-LED_LAUFSCHRIFT_ROT.pdf

To get started I had a look at the forums and found this topic: http://forum.processing.org/topic/processing-brg-led-display-signs where zach.gage posted some code, how he managed to talk to a LED sign by a different manufacturer.

The problem is that he connected the sign via parallel port, but I got a USB connection. So I am trying to figure out how I can send data to the device via USB.

Any ideas on how I can get started?

After quite a few more hours of research and testing it turns out that the Serial class is very well able to work with USB connections.
Copy code
  1. import processing.serial.*;
  2. Serial myPort;
  3. myPort = new Serial(this, Serial.list()[0], 9600);
  4. String myCommand = "command goes here";
  5. myPort.write(myCommand);
Thanks!
