Thanks, I did try google (however with refrence to SCDQ5581 or dot matrix displays). Problem is, they all using own libraries for different displays (in this case the display have 5x7 characters and totaly different pins than the SCDQ5581). Thats confusing for me, because I really dont understand much the datasheets and I realy dont know how to make my own library or whole own code.... For now I can just use existing codes and change them a little bit, but not rewrite them completly for different electronics. But thanks anyway, I will try to do smth with this, so far no luck....
