Hi Hans,

According to your info it uses a MAX7219. There is a JAL library for that display made by Rob Hamerling. 

Since there are more displays I think you need to use the library max2719_n where you can define the number of modules with n.

So give it a try 🙂.

Kind regards,

Rob

Hi,

I have used such a module, but only one.

Here, you have 4 modules that are daisy-chained: The DOUT of one is linked to DIN of the next.

As mentioned by Rob, they are based on the MAX7219, and the library works very well for me.

However, I didn't try the MAX7219_n library, but I am confident there should be no (bad) surprises.

Kr,

David
