okay, i finaly got it to work!!
i work with an int(16b) to display a 8bit(8 leds) led colom.
i bitshift 8 times to the left and then OR this with another int and itself.
like this:
printset[0][a]=dataset[dispthis][a]<<8;
printset2[0][a]=printset[0][a]|dataset[dispthis2][a];
now i get two characters behind eachother, then scroll them to the left.
When it scrolls 7 times i do the above trick again.
This in a loop will do the thing.
