Opel TID Display

Thanks for the OpelTID library
Unfortunately I’ve tried to use it, but it's not working.

I'm using the following code, and the only thing I see is sometimes a CD symbol : #include <TID.h>TID mydisplay(3,4,5);void setup(){}void loop() - Pastebin.com
I can change the symbol by changing the the value of i
But I'm not seeing any text.

I'm using a UNO R3 and i've tried 2 TID.
What I’m doing wrong ?
