32x32 RGB Matrix - Made with 2 16x32

Post by joschen »

Hello!

Our team is a little bit short on time, and we are interested in the 32x32 RGB Matrix from Adafruit, communicating with an Arduino.
The link to the one we are looking for is here: http://www.adafruit.com/products/1484

The 32x32 RGB Matrix has been out of stock for a while, so we've been thinking about connecting two 16x32 RGB toguether to simulate a 32x32 matrix.
We have seen the tutorial where they connect up to 18 panels toguether, http://learn.adafruit.com/adafruit-diy-led-video-wall, but we're unsure if this is compatible with the arduino.

Our main question is:
Is it possible to use two 16x32 RGB matrices from adafruit as a 32x32 RGB matrix, and would this matrix be compatible with the arduino?

Thank you!!

It is possible to connect multiple panels.

Compatibility with the Arduino depends on your definition of that term. The Arduino can generate signals the panels will display, but the displays have no built-in memory or PWM control. If you want to mix or fade colors you have to do the PWM in software, refreshing the whole screen each time a value changes.

Not "out of the box," no. The library, as written, is pretty tightly tied to the specific wiring for the 16x32 or 32x32 panels as-is.

That's not to say the code couldn't be adapted, but this is a guru-level modification.
