RGB 16x32 Improper display, screen is split in half

Post by chrism257 »

I have followed the tutorial provided by adafruit for wiring the 16x32 display.
Also, I have checked the forums and other websites without finding anyone else with the same issue.

Instead of pin 8, the CLK (top right white wire on the gray connector), has been moved to Pin 11 as stated in the tutorial.
Furthermore, I have used digital pins 24-29 for each set of R, G, and B wires.

Here is an image of the issue I'm dealing with: http://puu.sh/gnzN9/09d4da016a.jpg
The output should span the entire matrix and look something like this: http://prntscr.com/6d1kfx

Here is an image of my wiring.

Does anyone know why this issue might occur?

One of your address lines isn't working. Check them again, maybe try a different set of jumper wires.

I'm going to try that now. I'm also a bit confused as to why my matrix has the additional row address select 'D'.
In the tutorial, the 16x32 they have does not have this select whereas the 32x32 does.
