Cascading two (or more) 16x32 RGB Matrices

Post by mattjakob »

Hello,
I just bought two 16x32 RGB matrices and I am trying to figure out how to chain them together.
I made a ribbon cable to connect the output of the first matrix (the one connected to Arduino) to the input of the second matrix and the second matrix shows the same graphics as the first one (kind of 'mirror display mode').
What I would like to do now is display some graphics across the two matrices...

I read that apparently this has been done with an FPGA but I have no experience with those devices - I am using Arduino!

Any advice/input will be greatly appreciated!

Thanks

The matrices are something of a learning experience for us because we don't have any better docuementation for them than you can find posted in the tutorials.

As best we know, you chain the matrices by connecting them in series and sending twice as much data to each row. Post a photo of your setup and we'll see if we can find anything.
