see the attached picture. Basically what is happening is the first 16 rows are displaying both the first 16 rows and rows 17-32 on top of each other. Same thing is happening for the bottom half. I tried inputting a different led-panel-type and just was getting errors. Anyone run into this before and know what to try?

I am also using the electro dragon board with a Rpi2.

Yeah, I know exactly what's happening. Your HAT doesn't support 64 height. Depending on when you bought it you can modify it to support that much. Share a picture of your HAT and I'll show you what you need to do.

Appreciate the feedback and help!

Well, I thought I knew but that was when I thought you were using the Adafruit HAT. You'll have to consult the manufacturer of that HAT to find out how to use the E pin for multiplexing.

Documentation for that adapter (or a similar one) is here.

Matrices taller than 32 rows need an extra pin for the E address line.

That was the issue. I connected the E_BUF and P4 pins. Thanks everyone!
