hi Hari!

ive replicate your led matrix using your codes and only 74HC595 on both sides

but for some reason the output i got inverted and not like yours?

is there any reason for that?

hey,
maybe i can help ;)

  if (isOn)
   bitmap[row][zone] =  bitmap[row][zone] | colBit;
 else
   bitmap[row][zone] =  bitmap[row][zone] & (~colBit);

change the | colBit; with the & (~colBit); in the code and try again?
