You tried then all?
If 8x8 does not work,
Then try 16x8 or 8x16 instead.
Even though you have 8x8.

Ok on 8x16 it work,can see full scroling text on matrix,but on hardware text is raised upper by one position the top row is visible below.
when I select row 0 and column 0 LED, a second LED from the first column lights up.
how can the text be cut down one row below?
On simulation work ok.
