Hi, sorry I missed this post. Are you sure the displays are connected to each other correctly? Data out of one goes into Data in of the other?
Maybe you are missing one of the libraries required in the project? If it is not compiling, you'll get an error message letting you know why.
Hi. Yes, in this case, DIN (Data In) is the same as MOSI (Master out, Slave in). Have you just plugged a matrix into another Arduino to see if it works? Try trouble shooting the parts individually to see if they all actually work. For instance, maybe the matrix display’s you have are different are require a different library, to what I used.
