  I managed to drive a 32x32 RGB Panel with the tips above. 
  Looking at the vhd files of "logibone_mat.xise" is it possible to drive a 32x64 Panel with minor adjustments?
  Setting   nb_panels : positive := 4  for two  32x64, does not work nor does nb_panels : positive := 2. 

  Any ideas? Also the python script to display full-screen rectangle:

  
  

  map = ()

  g = 0x00F0

  count = 0

  for c in range(1024):

          g = count << 4

  map = map + (g & 0xFF, ((g >> 8) & 0xFF))

  count = count + 1

          if count > 15:

                  count = 0

  logi.logiWrite(MAT_ADDR, map)

  
  

  time.sleep(3)

  
  

  Leaves out a middle column as well as the first and last on a 32x32 Panel. Why is that?

  I wished I could use Glen Akins`s version but loading the bitfile will yield that my Revision (R1.5) of logibone is incompatible.
  How could one account for that in the .xise file?
