32x16 and 32x32 RGB LED Matrix, Tri-Color Displays with Arduino UNO

Post by wsg »

Is there a tutorial on chaining and a library code for using these Tri-Color LED Matrix Displays with an Arduino UNO or with the Arduino DUE?

What are the advantages for using a FPGA development board to do this instead of the Arduino UNO?

There is a tutorial using the DE0-Nano FPGA Board with
Adafruit 32x16 RGB LED Matrix Displays but there is not much information on the wiriing or code and there is no chain of multiple displays.

We don't have any Arduino-based examples for chaining these displays, reason being...well, you know the phrase "squeezing blood from a stone"? The limited resources of the Arduino make this difficult and of questionable utility, so we instead decided to focus on a single display with a passable color range and decent refresh rate.

Ray's Logic has been doing some work with chaining these displays using the Propeller platform:

The Arduino Due could very likely handle this, but the necessary code has not yet been written and we have no ETA.
