I tried to Display two char Arrays filled up with serial input :
Code: Select all
dmd.drawString( 2, 1, stringa , 5, WHITE,BLACK ); dmd.drawString( 2, 9, stringb , 5, WHITE,BLACK );
The DMD Show me my Array as it should, but if the next Array is shorter than that befor the old letters on that Position will be displayed to.
I don't know how to explain it better
1.)Array: asdf -> DMD: asdf
2.)Array: axdf -> DMD: axdf
3.)Array: ac -> DMD: acdf
So the only possible solution i found is to clear the complete Display but this produce a flicker.
Another possible solution is to fill up the arry with blank so it would Display the blank but this isn't a nice solution i think.
Are there any other possible solutions i can try?
